There is no respite for the fish in our local loch. Once lockdown was announced they were at least offered some relief from the human anglers pursuing them with all manner of artificial flies. Now that the lockdown has been eased, the fisher folk are back wielding their rods with even greater enthusiasm and tempting them with an even bigger range of flies.

There is no rest for the wicked or for the scaly occupants of these waters! Not that the tweed-clad anglers are the only threat the fish face. Out there are any number of fishers, some of them clad in feathers and some in fur. And it matters not how big or small those fish are, there is always something after them!

The grebes and goosanders that populate the loch. specialize in small fry, their submariner tactics enabling them to operate blithely underwater. I once had the pleasure of watching a great crested grebe from a cliff top high above the waters of a beautiful wee lochan. Those waters were crystal clear and so I was able to watch every nuance of the bird’s technique as it hunted for small fry in those pristine waters. It was an education to see how deftly it manoeuvered and how quick it was in running down those small fish.

After rather bigger prey, herons lurk around the edge of the loch at times statuesque as they exhibit such infinite patience waiting for fish of varying sizes to come within reach of that long, dagger like beak. Then in a flash they are pinioned and slide down that long neck. You can see as the caught fish slithers down towards the bird’s stomach. Then, a swirl in the water tells of the hunting otter in pursuit of larger prey. As nocturnal hunters they are seldom seen but, nevertheless, they also take their share.

But there are bigger fish and much larger hunters. Perhaps the most spectacular are the ospreys, now well established around these waters and taking their share of the trout so eagerly sought by the angling folk. Ospreys are, of course, mighty hunters. First, they scour the waters of the loch from on high for fish before setting their sights on a likely target, probably a fish innocently languishing close to the surface completely unaware of the danger that comes from above. The bird pauses, goes into a short hover, then begins its dramatic descent, a shallow dive. Gathering speed, it homes in on its target and hits the water feet first with a mighty splash. Then it grapples with its slippery prey before its mighty wings thrash, as slowly it lifts itself clear of the water, clutching its victim, often with one lethally taloned foot. As it rises clear of the water it adjusts its grip, securing the fish with both feet, shakes itself free of surplus water and makes a beeline for its eyrie where its mate and a bevy of youngsters await.

The ospreys may be lethal and sizeable hunters but now on the horizon is another even mightier hunter, a sea eagle. Here we are looking at a bird with an enormous eight-foot wingspan, colloquially known as a ‘flying barn door’. The presence of a sea eagle over the loch and possibly two of them, came to light when the wildlife photographer Gordon Buchanan was filming a pair of ospreys on their eyrie for the “Springwatch” television programme. Since then, there have been several sightings although as yet I have still to see them.

Sea eagles don’t so much take the plunge in their quest for fish, as take them from the surface or near it. They are perhaps fish snatchers but are equally adept at taking large trout which, as the loch is stocked for commercial fishing, provides really good feeding for both ospreys and sea eagles.  However, it remains to be seen if the sea eagles settle here as I suspect these are likely to be young birds exploring the area for a suitable territory. Their choice, should they stay, is sure to be beneficial to them although I’m not sure how the presence of these mighty fishers will go down with the anglers.

The sea eagle was once commonplace throughout Britain but during the killing years of the early twentieth century, they were perceived as a threat to anglers and as a result were so severely persecuted that they became extinct as British breeding birds. The last ones were exterminated in about 1916 at around the same time as the last pair of breeding ospreys were similarly eliminated. During the past few years, sea eagles have been restored to parts of Scotland and more recently to the Isle of Wight off England’s southern coast. One of the more recent releases of birds brought in from Scandinavia was in Fife and this pair may well have travelled from there as they prospect for territory.

How the ospreys might react to sea eagles is hard to predict but there are plenty of fish to go around as the loch is well stocked. The real difference between the ospreys and the sea eagles is that the ospreys are migratory birds of course, so once they have departed by September, the sea eagles would have the loch to themselves. Meanwhile the ospreys’ fishing also has a sense of urgency, for at present they are nurturing two chicks but by the end of August the adult birds will instinctively turn their heads southwards and leave for the winter.

The young ospreys have just about reached the stage when they are beginning to station themselves on the edge of the eyrie and exercise their wings. Eventually, and by the time August is on the calendar, they will finally take to the wing. However, time is short as the parents will then have to teach their two youngsters to emulate them and pluck fish from the waters of the loch. As said, time is of the essence for come the end of August the parent birds, having lavished so much tender loving care on their brace of young, will abruptly leave, setting out on their several thousand-mile journey to West Africa. The youngsters will suddenly find themselves very much on their own. No more nurturing, no more training, but ahead of them that enormous journey across continents and oceans to reach the same destination as their parents.

Thus, there is a lot of learning to do before the end of August. However, for the time being they can at least rely on the guidance and efforts of their parents. The learning curve is certainly steep so this is probably the most important period of their lives and one that is utterly vital to their survival. Their first efforts to catch fish are likely to end in disaster but they will have no more than a month in which to sharpen that skill sufficiently to enable them to maintain themselves and sustain that flight of thousands of miles.

Significantly, when Spring arrives, these youngsters will not return to Scotland. Indeed, it may well be three years before they undertake that journey. In the meantime, they will stay in West Africa, properly honing their fishing skills in the fish-rich waters there. How hard it is to survive is emphasized by the fact that even experienced adult birds do not succeed every time they dive for fish. Indeed, when conditions are hostile and visibility hampered by rough water, they make take several sorties before they meet with success,

So, now we enter the last vital chapter in the story of this year’s young ospreys. They must learn and learn fast to be self-sufficient. This is ‘gone fishing’ with a real purpose. Otherwise they will pay the ultimate price.

Those of us who have spent a lifetime or the best part of a lifetime playing sport or being involved in sporting activity, have indulged ourselves for a variety of reasons. Some are imbued with that competitive edge, others seem to lack that stimulus.

Those of us with that competitive instinct find It drives us to be involved and of course, to compete whether it be as part of a team or as individuals. Each to his or her own. Some are happier as individuals whereas others fit seamlessly into the team ethos. Yet even as part of a team, individual competitiveness is a driving force. Being involved in sporting activity is part of life’s training. It requires a certain degree of physical fitness. It needs self-discipline and it helps develop social skills, all of which translate to important characteristics in later life.

In essence, animals and even birds are no different. For some of them the competitiveness that will drive them to face all sorts of challenges just to stay alive is learned at an early stage of their lives. For example, anyone who has done any meaningful badger watching will be aware of the importance of play to badger cubs. Down the years, I have avidly watched badgers and have therefore seen the cubs romp and play- fight for hours on end. I was so enthusiastic about my local badgers that I watched them incessantly and was thus able to follow their lives and learn just how the cubs grew up.

Their play-fighting established a pecking order that would be with them for the entirety of their lives. There are winners and losers and these ranks are recognised early in their lives through that play as a result of which, high or low and presumably, future status within the group is established. For example, I remember watching a family of three cubs on the May evening when they first emerged from the darkness of the parental sett. On that occasion there was no playing, just a tenseness caused by the totally new experience of seeing and being in the wider world for the very first time.

Within days, however, they were playing with gay abandon and much noise, chasing round after each other and challenging each other in a crazy game of king of the castle. Soon, it became clear that one of them was very competitive and constantly the winner in this contest. He – I think it was a young boar – was the permanent king of that particular castle and even in those very young days, he was learning his place in the world, especially in relationship to his siblings. Incidentally, the sett was located in a strip of woodland behind a popular guest house and as days shortened and autumn replaced summer, it was lit up by the approaching headlights of visiting cars. Thus, even as summer had passed and autumn’s darkness descended, I was able to watch those same badgers by torchlight because they had got used to operating in the glow of headlights.

I have also watched fox cubs similarly indulge in play-fighting and even on one occasion watched badger cubs and fox cubs romp together where a pair of foxes had taken over an outlying section of a badger sett. This play is just as important to fox cubs as it is to badger cubs and they too eventually form a pecking order among the siblings, the status then established presumably carried on into adulthood. All the time they are playing, they are developing the skills that will see them through their entire lives.

Perhaps it comes as no surprise that such ‘advanced’ animals also play. Those who have the company of dogs or cats, will, I’m sure, be familiar with the way puppies and kittens play, either with each other given the chance or with us. Play is very much a part of their upbringing just as it is for fox and badger cubs. It prepares them for the rigours of the life they must lead and sets them up for the future. This kind of play is a learning process and as much a part of the growing period in people as it is with animals.

However, we don’t associate play in the same way with birds. Yet every autumn and winter I see plenty of evidence of play in birds when autumnal and winter winds blow. It is then that hordes of rooks and jackdaws indulge in games of aerial tag and much more. We may view with a certain amount of disdain, members of the crow clan but believe me these are birds of high intelligence and indeed that high IQ may well be exhibited in their wild play on such occasions. Sometimes they chase each other and at times, appear to compete with one another to perform the most outlandish examples of spectacular aerial antics, diving, soaring – all at breakneck speed.  Rooks and jackdaws are clearly very skilled flyers.

All this is also part of play and is probably a constant rehearsal of acrobatic flying that on occasions may get the birds out of trouble with predators. Yet I cannot help but think these antics provide an atmosphere of sheer pleasure too. Perhaps they do it because they enjoy it and indeed it must be an enjoyable experience to challenge the elements with such verve, skill and speed.

Avian play may not seem to be likely yet other incidents have served to provide further food for thought. As I recently reported, a pair of magpies have this summer produced a brood of four youngsters in a neighbour’s garden which we are seeing quite a lot of in the vicinity of our bird-table. I have also reported on the regular presence of a cock pheasant with a distinct limp which we have named ‘Hopalong’. Hopalong has recently lost his tail feathers but whether or not he is therefore slow to get into the air because of his gammy leg, I do not know but he has perhaps been grabbed by a dog or even a fox and lost his tail.

Now he has been joined by an attractive hen pheasant, which is also coming regularly to feed on the   fragments of food from below our bird-table and she is complete in that she has a tail!  Indeed, it is her tail that has been a focus for attention. As she potters around, one of the magpies is repeatedly following her.  It is the pheasant’s tail that seems to be the attraction. The magpie stalks behind the pheasant and from time to time tweaks her tail before hastily retreating, not just once but repeatedly. Is this a sign of sheer mischievousness on the part of the magpie? Is it just playing?

The only comparison I can strike comes from one of the many books written during the last century by Frances Pitt, a naturalist of great experience. In one of her many books she recounts the story of her two captive ravens which apparently wandered freely around her garden. The ravens had a game which they repeatedly played on one of Miss Pitt’s cats. The first raven would face the cat and taunt it whilst the other would sidle behind the cat and tweak its tail. Immediately, the cat would wheel around to face its tormentor at which point the first raven would then tweak the cat’s tail. This mischief was repeated until the poor cat eventually sloped off in disgust and much affronted after it had ended up virtually going round and round in circles!

So, it seems, birds too can play. At least that seems to be the case as far as the crow clan are concerned. All the research tells us that crows are well ahead of the game when it comes to intelligence - far ahead of other avian species. However just a few years ago, I once witnessed a buzzard flying above a seashore, repeatedly dropping a stone and diving to catch it time and time again. It must have been playing! There’s no other explanation. Perhaps whilst they are playing, they are experiencing their own capabilities?

A pall of silence has descended upon the landscape as the avian breeding season largely comes to its close. Birds are taking a well-earned rest after the rigours of a frantically busy summer producing and rearing the next generation or in some cases, generations.

 

Now they must begin to prepare themselves for the winter that lies ahead. During these next few weeks, the theme is one of renewal as most of them enter their one main moult of the year.

However, some still have work to do and the local ospreys must continue to nurture their two chicks. For them there is a sense of urgency because in a few weeks’ time and by the end of August, they will depart for Africa to be followed shortly and independently by their youngsters who, of course, have yet to take to the wing. The swallows and house martins also still have work to do. Martins almost always produce three broods of youngsters during their sojourn here so they literally do have another generation to nurture before they migrate. Swallows also sometimes produce three broods although right now they have to complete their rearing of brood number two. It does seem to have been a particularly productive year for the avian community.

And, the woodpeckers are still busy feeding their broods of redcaps, albeit that some of the these are already quite self-sufficient and feeding for themselves. However, they are still eager to take advantage of their parent’s generosity. There is still one here which flies in to the bird-table and clings like a limpet to the supporting post waiting for one of its parents to peck vigorously away at the fat balls and come spiraling down to feed it.  Young sparrows continue to be fed by their parents, although the parent sparrows are also moulting, and young magpies are also still looking for food mithering a parent bird unmercifully until it rams it down their throats.

There are young bluetits and great tits beginning to be self-sufficient although the parent birds are certainly looking tatty as they begin to lose more and more feathers. The warblers too are looking pretty ragged and are clearly going into the moult as well, although the willow warbler that has occupied my garden this summer has certainly stopped singing and is undergoing one of its two moults, the second occurring on their wintering ground in Africa during our winter. Willow warblers are unique in going through this process twice every year although this is hardly surprising considering their lifestyle which has them constantly to-ing and fro-ing through thick vegetation to reach their well-hidden nests in order to feed their young. Swallows and martins similarly wait until they have returned to their African wintering grounds before they go through the replacement of their plumage, which means they must tackle their migratory journey with old feathers rather than new.

The replacement of feathers is a constant process. As feathers become worn, they are replaced with new ones growing in the same follicles and slowly replacing old ones that are cast. Birds, not because they are fashion conscious but because their plumage takes a bit of a bashing throughout their lives need that constant process of renewal to stay in top condition. But all birds, barring the willow warblers, go through one main moult every year of their lives, a major overhaul of their plumage. When this occurs, birds are to some degree quite badly debilitated and indeed some waterfowl, because they tend to shed all their wing feathers at once, become totally flightless at this time resorting to skulking about in the likes of reed beds to stay safe during this period.

Feathers are, however, replaced in a uniform way and more or less in pairs with feathers from either side of the body being cast and replaced. The first to be lost are generally the wing and tail feathers which are each replaced in turn. As may be imagined, the most discomfort occurs when the wing feathers are lost and that is why most birds cease to give voice once the moult begins, although this week I did hear a solitary blackbird that was still full of song. Perhaps this one has delayed its moult because it is still rearing a second or even a third brood of youngsters. Also contradicting the general rule, a garden warbler and a wren are clearly still in the mood for singing. Generally however, that pall of silence is what we notice in July and August, especially after a summer which has seemed so full of rich bird-song.

Other species also migrate to moult, for example, Canada geese, which of course are not native to these shores but introduced from America several hundred years ago.  These, which were brought in to decorate the ornamental ponds and lakes devised by landscape architects such as Capability Brown, now indulge in a migratory flight from England, where there are now substantial populations of them, to the Beauly Firth in the north of Scotland. Indeed, the reason why here in Scotland we now also have a burgeoning population of Canada geese is undoubtedly connected to this migration. Doubtless some of these geese saw opportunity during their returning flights to select and settle in places where the environment was suitable and where there was evidently little or no competition from other breeds of geese which of course are largely absent from these shores during the summer months.  One of the other birds that migrate to the north for the purpose of moulting are eider ducks. Up to four thousand eiders are to be seen off the Aberdeenshire coast during July.

Most birds avoid moulting during the breeding season but there are exceptions to this rule as female sparrowhawks and peregrine falcons do so, perhaps buoyed by the fact that most of the hunting and therefore the supply of food for their young is carried out by the males.  The timing of the main moult appears to happen when food is still plentiful. Thus, although debilitated by the loss of plumage, birds are still able to find sufficient food to sustain them. That it occurs largely after the breeding season and at a time when almost imperceptibly daylight hours are beginning to wane, is also a factor. But by July, the main job of rearing families is for most birds complete. Obviously, the ospreys take their time to complete the rearing and training of their young and swallows and martins, indulging in multi broods, do not fit this profile.

So, it is the sound of silence that now descends. As explained, whilst they are in the moult, birds are more vulnerable with their flight in some cases impaired, in others absent. Therefore, they really do not want to advertise their presence as they are more vulnerable to predators. Consequently, they look particularly tatty and that was certainly the case when I visited a friend who has a multitude of birds in her garden, bluetits, great tits and coal tits to name but a few. They all looked as if they needed a good wash and brush up!

While the nation was in lockdown because of Covid-19, there were those taking advantage of the situation by perpetrating wildlife crime. The authorities were and still are pre-occupied trying to control a public so long constrained by lockdown that now people are taking liberties and at the same time putting themselves and others at risk. And of course, there has been a lack of volunteers who would normally be available to help guard vulnerable nesting sites. Hence, the wildlife criminals – I do not mince my words – have once again seized the opportunity to pursue their nefarious ways.

 

For example, there has been an increase in the illegal killing of raptors throughout the UK. It has to be said that most of these crimes occur in areas where shooting is popular – either an unhappy coincidence or a pointer to the root cause of such activity. And now I read that in Derbyshire’s Peak District, where Britain’s first National Park was established, peregrine falcons have been targeted and their eggs and chicks taken to be reared and later sold for vast sums of money.

Peregrines have had a chequered history down the years. When it was a royal sport, falcons were in great demand and of course not protected by the law, so that young falcons were regularly taken by enthusiasts for the sport. Of course, these days such activities are strictly illegal with most falconer’s birds supposed to be captive bred. But now some with eyes firmly riveted on their wallets, are returning to the bad old ways and taking young falcons from the wild or their eggs which of course go into incubators to produce youngsters.

Peregrines were very much under pressure during the war years, especially on England’s south coast, because of their predation upon carrier pigeons bringing messages from the front or indeed from aircraft that had been shot down. However, once hostilities ceased, peregrines were once again protected only to suffer from the use of new pesticides - most notably DDT - in the immediate post war years. Treated seed ingested by the pigeons that were their main prey, carried on down through the food chain and peregrines and other birds of prey first started to become infertile and then die. Hence, such noxious chemicals were controlled, and in some cases banned.

Now peregrines are under threat again, so valued by those who follow the sport of falconry that they are prepared to pay big money for young falcons – up to £8,000 a bird. Among the most enthusiastic followers of the sport are Middle Eastern in origin. Those, who have got rich on the world’s dependency on oil, have the resources to pay that kind of money for what is generally regarded as the king of all falconry birds.

I must confess that seeing such a bird in action is indeed a thrilling sight as you might expect of a bird that is capable of exceeding 200 miles per hour in the stoop. I have watched peregrines on many occasions yet one memory from a glen where I once spent a good deal of my time, sticks in my mind. I had been scaling the side of the glen when a peregrine took off from a rocky ledge above me and drifted down the glen below me. Suddenly I was aware of a little posse of pigeons a long way down and clearly the peregrine had noticed the same group and now began to home in on them. I’m sure my jaw dropped when I saw the falcon accelerate as it made a bee-line for the pigeons.  With the peregrine now travelling at considerable speed, it rapidly overhauled them and finally hit one of them a mighty blow sufficient to decapitate and kill the victim instantly. It then followed the tumbling body down into the glen - lunch had been served!

The report I recently read suggested that three of the estimated 40 peregrine nests in that part of the Peak District National Park had been robbed of either their eggs or young chicks resulting in a serious depletion of the Park’s peregrine population which, if repeated in other parts of the country, would result in a significant reduction in peregrine populations.

Add to that the killing of raptors such as hen harriers, which has been occurring on or near grouse moors, not to mention golden eagles and of course peregrine falcons and buzzards and we are beginning to slide down a very slippery slope which begs the question, are we returning to the bad old days when all raptors and indeed all carnivores, plus hedgehogs were unmercifully and universally slaughtered with impunity? All as a measure designed to protect game.

These days, there is much more awareness of the precious wildlife resource we have in these islands, much more desire to protect that resource and laws that give it vital protection. No such laws existed when open war against such creatures was pursued towards the end of the nineteenth century and during the early years of the twentieth century. Even such birds as ospreys were killed willy-nilly and by 1916, had been driven to extinction as breeding birds in Britain. Miraculously, during the 1950s ospreys returned to Scotland of their own volition and with considerable help from many volunteers as well as professional organisations, re-established themselves.

Sea Eagles were similarly eliminated and red kites too, save for a rump of them that hung on in central Wales. Were they eliminated by those who follow the sport of shooting - who knows? Both these birds have been successfully re-introduced in recent years and are now prospering again. But clearly there are those who have only their interest in shooting birds such as red grouse at heart and care not a fig for the likes of harriers, kites, buzzards, peregrines and eagles. And those currently in possession of peregrine chicks taken from the wild either as eggs or chicks, have no interest in the survival of these magnificent raptors in our countryside.

Shooting brings substantial income for some landowners and some suggest that  is probably the root cause of the killing of birds of prey, whether or not the perpetrators of these crimes are directly or indirectly connected with them or those who shoot. Now the theft and selling of peregrine falcons by people who clearly know their birds of prey and where they are to be found, is a growing problem. These people have only the profit motive in their minds when they steal eggs or chicks which, as previously said, they can sell for vast sums of money on the international market.

We need to take wildlife crimes such as these very seriously and all of us should always remain vigilant especially if we are aware of the presence of these birds in our own area. These are as much crimes as common theft or burglary - crimes which most of us universally condemn. They should not be tolerated by anyone and the full force of the law should be brought to bear on the offenders.

There is a gradual lulling of the sounds of summer as birds now find it not quite so important to declare their territorial boundaries.  Most disputes over territory were settled some time ago although in many cases, cock blackbirds and thrushes have resumed song whilst their mates start all over again incubating their next clutches.

Other birds are kept busy feeding their fast growing broods.  For example, it has been recorded that in a single day a pair of great tits brought their brood no fewer than 900 meals ….. one every daylight minute.

The fact is that tits notoriously go in for large families – sometimes into double figures – and further, that tits are very rapid developers requiring a mere fortnight to be on the wing  Thus, their growth rate and their requirement for food is astonishing.  Many of the smaller birds follow this pattern – large and a rapid turnover of clutches and a consequential need for the youngsters to become self-sufficient in as short a space of time as possible.

The contrast between this pattern and that followed by birds of prey is considerable.  One clutch is quite enough for our predatory birds and in general their clutches are relatively small.  The incubation period also differs – a mere fortnight for many small birds whilst a month or longer is the norm for most predators. Even then, there is frequently a long feeding period required before the offspring are capable of going it alone.

Therefore, it did not surprise me to find myself gazing skyward at the weekend to admire a pair of circling buzzards.  I watched them come off the cliff face, where they nest, and soar into a brilliant blue sky flecked with massive pillars of frothy white clouds.  As they drifted across the blazing sun their plumage seemed to be fired with light.  I don’t think that they were going anywhere in particular, nor do I think they were eager to hunt but I am quite sure they will have a healthy brood of two, perhaps three youngsters, probably a week or two old.  With a healthy and numerous population of rabbits pockmarking the fields below their eyrie, there will be no shortage of food.  Their chicks, much less than expecting a feed every few minutes, will, especially at this stage, will only require food three or four times a day.

Thus, relieved of the need to sit tight on her eggs, the hen was simply joining her mate in some pleasant aerial exercise.  And, whilst the survival technique of great tits and many other small birds is to produce offspring like peas in a pod, rows and rows of them, clutch after clutch, most large birds of prey produce relatively small single clutches of two or three.

But all birds of prey have devised a particular recipe for survival which sees a vast difference in size between the oldest and the youngest in a clutch.  This ‘staggering’ of their young is, first of all, a result of a delay in the laying of their eggs.  Secondly, it ensures that, except in the most adverse circumstances, at least the largest of the clutch will survive.  In years of the shortage of natural food, the youngest – the smallest – will fail and often provide its fellow nestlings with a somewhat grisly means of survival!  So nature plays the percentage game – a game which, whatever the formula, is an almost certain guarantee of survival at least for the fittest and strongest.

In most cases, come the end of the summer the youngsters will have to find their own way in the world. The parents that nurtured them so carefully throughout the summer will expel them, sometimes most forcibly, from their territory as the leaves begin to turn.

The nurturing is a long process in birds such as eagles.  Their young, and often only one clutch of two will survive, do not fly until they are about three months old.  Buzzards cut that time to about seven weeks.

That hen buzzard would also be free to leave her youngsters for a while because this particular eyrie is south facing and, on the day of my excursion, warmed by the heat of the June sun and protected by the cliff from the chilly northerly wind.

Mind you, with the youngsters only recently hatched, the demand for food, though constant, will be satisfied by a couple of plump young rabbits, at least for a while. However, as their young grow, those two buzzards will have to work progressively harder.

The same pattern is repeated ospreys.  One good fish will keep the newly hatched youngsters going for quite a while, even though the male bird, who does most of the food fetching initially, will always take his fill of each catch before presenting it for the female to feed, first her young and then herself.  However, as the summer progresses, a greater sense of urgency will build as the female will have to contribute to fetching the food. The urgency is accentuated by the knowledge that the young ospreys will have to be fit to undertake a journey to Africa in September.  In a bad fishing season, some simply don’t make it.

So whilst the smaller birds busy themselves rolling clutch after clutch off the production line, birds of prey taken their time, concentrating on their one family of the year and I suspect that there will be less time available for those buzzard parents I watched, to cavort about the sky.  There is a job to be done.

 

Any natural place contains an infinite reservoir of information, and therefore the potential for inexhaustible new discoveries.
