Wild about...Butterflies and other insects 2012

Wild about...butterflies and other insects 2012

  The sanctuary and surrounding landscape journeys through a calender of changeable faces. Some appear dramatic, inspiring mood and thought, but it never seems so beautiful as when the sun breathes warmth and light into burgeoning plants, and the wildflowers begin to bloom. It is at such times that the insects gather to  feed on the leaves, petals and stems, and drink on the sweet, clear nectar. The sanctuary homes an unimaginable variety of insect species, but none are quite as enchanting or uplifting as the butterflies.

Comma butterfly (Polygonia c-album)


  Compared to other butterflies, the comma can look dishevelled and frayed, as if cut from a careless template by a jagged edge scissors. Despite being distinctively orange, it can easily disappear into its woodland surroundings simply by closing its wings. It gets its name from the small white mark on the underside of its wings, resembling a comma. It has been photographed here on a bramble, an important food source for this and many butterflies.

Peacock butterfly (Inachis io)

  The peacock butterfly is instantly recognisable by the distinctive eye spots on the tips of each of its four wings. Appearing as the eyes of a much larger animal, it can help the butterfly ward off predators. This bright red / orange butterfly also has a darker underside to help camouflage them into the wooded background. The one photographed on the bluebell, a natural food source for the peacock butterfly, is faded, possibly after hibernation.

Small copper (Lycaena phlaeas)

  Adult small copper butterflies will feed on buttercups, dandelions, ragwort, red clover, and yarrow, all of which can be found in and around the sanctuary. This particular butterfly proved quite difficult to photograph, being nimble in flight and never settling for long.

Common blue (polyommatus icarus)

  A beautiful butterfly that looks impressive against its natural green environment. At the sanctuary, it was found away from woodland, near tall grasses and thistles.

Small tortoiseshell (Aglais urticae)

  The small tortoiseshell is another of the orange butterflies. Patterned in black and pale yellow, with an irregular blue fringe, there were many sightings through 2012, particularly outside the wood. This probably reflects the abundance of local plantlife it uses for food.


Green-veined white (Pieris napi)

  The green-veined white is easily mistaken for other pale coloured species, of which there are many fluttering around the local woodland. It can be particularly difficult to identify in flight, however, here it can be seen feeding on the many available food sources.
 

Orange tip butterfly (Anthocharis cardamines)

  Its name comes from the distinctive orange wing-tips of the male, which are absent from the female. This makes it difficult to distinguish the female from other pale coloured butterflies, particularly in flight.

Large white (Pieris brassicae)

    Another pale coloured butterfly that can be difficult to distinguish from other similar looking species. The above is female, identified by the two black upper-side spots that are absent on the male. The large white was prevalent in the woods where many of its food providing wild flowers grow.

Speckled wood (Pararge aegeria)

  Abundant woodland butterfly that feeds on many of the available plants, including: bramble, ragwort and cuckoo flower.

Ringlet (Aphantopus hyperantus)

  When settled on a plant, as is this one, the ringlet is quite easy to identify, with its white-centred black spots, ringed in gold. The brown wings are fringed with white. Another bramble feeder, it will also gather nectar from the local ragwort and thistles.

Gatekeeper (Pyronia tithonus)

                 

  The gatekeeper is a mix of orange and brown. The male (above) can be distinguished by the dark markings on its forewings. It can be mistaken for the meadow brown, particularly in flight. Another butterfly to utilise bramble.

Meadow brown (Maniola jurtina)


  As its name suggest, the meadow brown was primarily found in open, natural grasslands, where their food plants were allowed to grow untouched. Was not seen at all in the wooded areas around the sanctuary.

Red admiral larvae (Vanessa atalanta)

  Seeing these caterpillars was a bit of a surprise given that I can't recall seeing (or at least accurately identifying) a red admiral butterfly around the sanctuary in 2012. The presence of these five caterpillars on the woodland edges at least confirms they were present, although the quantity is unknown.

Cinnabar moth caterpillar (Tyria jacobaeae)


  These yellow and black cinnabar moth caterpillars were destined to re-emerge as bright red and black moths. The female lays eggs on the ragwort, on which the caterpillars then feed.

Other insects

Yellow shell moth (Camptogramma bilineata)

  Upon my approach, this yellow shell moth flew from the path to the undergrowth, where it hid at the base of tall grass. It had the most amazing pale green eyes.

Large yellow underwing (Noctua pronuba)


  Unusually about in daylight, this large yellow underwing was walking amongst the grass on the woodland floor.

Vine weevil (Otiorhynchus sulcatus)

  Put vine weevil into an internet search engine and you will find any number of ways to destroy them. Seen as the destructor of garden plants, it is a flightless beetle with a narrow head. This one was photographed in the local woodland, where it can enjoy the variety of plants without the threat of poisons.

Green tiger beetle (Cicindela campestris)

  As the name suggests, this tiger beetle is green with pale spots. As this picture shows, this beetle prefers ground unhampered with too much vegetation.

Noon fly (Mesembrina meridiana)

  A fantastic looking fly with a shiny black body adorned with metallic gold trimmings. Seen here basking in the open sunshine.

Stilt bug (Metatropis rufescens)

  Orange / brown coloured bug with long spindly legs, photographed here on the plants of open grassland.

Scorpion fly (Panorpa sp.)


  The photograph doesn't do justice to the oddity that is the scorpion fly. It has a scorpion like tail that curls up at the back but lacks the potency of its namesake. It also has a long projection from its face, through which it feeds on insects.

Wild about...birds 2012 

  If "exotic" is the euphemism given to animals who, for one reason or another, find themselves far from their natural environment, then there are many exotic animals who have found a necessary home at Wales Ape and Monkey Sanctuary. But there are also many species of animal and plant that are there as nature intended. As the gateway to the Brecon Beacons, the Sanctuary is surrounded by rolling hills, clustered woodlands, and winding rivers and streams, all of which provide the ideal environment for a variety of birds. Listed here are some of those identified during 2012. It is strictly an amateur's guide, so feel free to question, correct or comment.

Mallard (Anas platyrhynchos)


Arriving with their typical splash and crash

  The transition from Cefn-yr-Erw hill farm to Wales Ape and Monkey Sanctuary has, over time, necessitated alterations to the landscape, but many of the local birds have adapted and even benefited from some of those changes. A clay-based field, susceptible to water-logging, has been crafted into an island for baboons. Mallard ducks have now made a home on the surrounding water, as well as a lone moorhen. In previous years, it has even homed Canada geese.

...while the female shows the ducklings the rest of the Sanctuary.

   The mallards can be seen taking strolls around the sanctuary's grounds, often with their young in tow come spring and summer. As well as sharing the water surrounding Baboon Island, the mallards can be seen on the local River Tawe and Nant Llech. In July, a female mallard could be seen on one of the local natural ponds, keeping her five or six ducklings close by. One was riding on her back. Upon sight of me, she headed into the longer grasses, ensuring the safety of her family.

Despite my distance, the female mallard leads her ducklings deeper into the rushes.

Moorhen (Gallinula chloropus)

  When the resident baboons disappear indoors, the moorhen will also explore the island.  As well as water plants and seeds, it will feed on insects, snails, and worms, so there is ample food to be had here. But it might well be the regular morsels of fruit discarded by the baboons that make this such an attractive place to live. When the baboons return, the moorhen can be seen scuttling for the water. Being a black-bodied bird with a distinctive red and yellow bill, it is highly visible on the island. Moorhens can also be seen along the River Tawe, as well as the canals of nearby towns.
  Chaffinches and house sparrows have also adapted to changes at the sanctuary, and are often found in the enclosures, feeding on morsels of dropped food. Meals at the sanctuary are regular, which naturally makes the residents less concerned about food than they otherwise would be in the wild. The wood chipping base that covers many of the enclosures create a welcoming environment for spiders, beetles and insects. While the primates are fond of such a snack, they are also a staple for many UK birds.

Chaffinch (Fringilla coelebs)

Male chaffinch

  There is a healthy year-round population of chaffinches at the sanctuary.The males are more colourful, with a distinctive red belly, face and breast, and a distinguished grey crown. The female's are lighter but with similar markings on the wing. Both have short stout bills that they use to eat insects and seeds.

House sparrow (Passer domesticus)

  In the last thirty years, the UK population of house sparrows has declined significantly, dropping by up to 70% (rspb.co.uk). It is difficult to know the trend of the sanctuary population during this time, but there presently appears to be healthy numbers of house sparrows in relation to other species of birds. It is possible that the out buildings and roof spaces, as well as the prevalence of food,  has helped preserve a positive population of sparrows.

  Sparrows congregate in groups, and are rarely seen in isolation. The male's brown back is streaked with black, while the front and crown are grey. The female is much lighter with a stripe across the eye. 

Swallows (Hirundo rustica)

  The summer months saw the return of the swallows, filling the sanctuary's skies with a frenzy of arrows. Their flight is quite a spectacle, as they swoop and soar with a carefree grace before closely turning into sharp, frenetic angles. Their agility in flight is greatly assisted by those long tail feathers. The speed and purpose with which they enter and leave the barn, where they assume nesting privileges, is reminiscent of Bond flying his Acrostar mini-jet through the hanger in Octopussy. 

                                             
  It is only when they stop to survey their surroundings on the overhead cables that you see how distinctive they are, with their strongly forked tail, slick lines and ruddy faces. They have usually flown by the time the autumn leaves have fallen, and return again with the approaching summer. It will be interesting to see how the changing climate, and increasing rain, effects the behaviour of the annually returning swallow population.

Pied wagtail (Motacilla alba)

  A species more frequently observed in the surrounding fields, this particular pied wagtail perched itself on the main barn for a closer look at sanctuary life. It has a long tail which frantically wags (hence the name) while standing, as if overcome with nervous energy. It is another keen insect eater. It has a curious undulating flight pattern which makes it look like it will fall from the sky after every stroke.

Starling (Sturnus vulgaris)

  Recent years have seen an alarming decline in the number of UK starlings. While remaining a relatively common bird, the RSPB's 2012 "Garden Birdwatch" (rspb.org.uk) recorded a ten year fall of approximately one third. It will be interesting to see whether that trend is followed by the sanctuary's starlings, and what the long term future is for this traditionally familiar sight. Often taken for granted, it is only up close that this bird can be truly appreciated, with its oil-slick feathers glistening blue, purple and green in the sunlight.

  Roosting starlings remain one of nature's most entrancing sights. Drifting shapes swoop and weave across the sky as thousands of starlings converge into one enigmatic display.

Blackbird (Turdus merula)

  One of the most familiar and easily identifiable birds is the male blackbird, with its black feathered body and bright orange bill. It also has a distinctive eye-ring. Seen in gardens and parks across the UK, they can be quite tolerant of humans in close proximity, particularly when used to garden behaviour.

Male blackbird (above). Below with female.

  The female blackbird is not so easy to identify, given that she is brown and can closely resemble a thrush. 

Song thrush (Turdus philomelus)

  The population of UK song thrushes is in serious decline (rspb.org.uk), but they can be seen in the  sanctuary's surrounding woodland, usually between the branches of bushes and proximate trees. Similar to the mistle thrush, it is known for its sweet melodious song. Given its prominent decline, the progress of the local population will be a matter of interest and concern.


Goldfinch (Carduelis carduelis)

Goldfinch hiding its distinctive red face behind a branch.

  In contrast to the abundant chaffinches, both the goldfinch and the bullfinch are less obvious species at the sanctuary. Although present, I noted just a few sightings of goldfinches 2012. The goldfinch has a distinctive red face.

Bullfinch (Pyrrhula pyrrhula)

Although this bullfinch is turned away from the camera,  you can just see it has something that resembles one of the tree buds in its mouth.

  During 2012, I noticed only one bullfinch at the sanctuary. Despite the males significant red colouration, these shy birds can be difficult to spot.

Robin (Erithacus rubecula)

  Synonymous with winter, and Christmas in particular, the robin is a regular sight at the sanctuary all year round. Perhaps the easiest of all UK birds to identify, with its plump body and bright orange-red face and breast. A juvenile can be more difficult to identify, without the trademark colouring.
  I have noticed that woodland robins, not so familiar with human activity, are a lot more skittish than those that make use of gardens and quickly become accustomed to human routine. It is likely that the people the garden robins encounter are those who fill feeders and are generally welcoming, and so have mainly positive associations. 
 Garden robins can get territorial, and have been known to display inter-species aggression. Yet during the RSPB's 2012 garden birdwatch, I counted 5 adults who did not appear to have any problem sharing the garden space. This might have something to do with the amount of food available, and thus the perceived threat of competition.

Blue tit (Cyanistes caeruleus)

  The blue tit is one of the smaller birds. With its distinctive yellow belly and breast, and bright blue crown, there is little chance of mistaking it for any other bird. Highly visible amongst the sanctuary's trees and hedgerows, it is a frequent visitor to the surrounding gardens' feeders. During 2012 they would often be found in the company of other tits, sparrows and finches, collectively making a warning sound whenever any perceived danger drew near. These calls could be heard reverberating ahead of me through the woodland, in anticipation of my every step.




Coal tit (Periparus ater)

  The coal tit is slightly smaller than the blue tit (yet surprisingly feisty for its size), and distinguished from the similar marsh and willow tits by the white patch at the back of its black cap. With a buff coloured front, it is not as colourful as the other tits, but is another familiar bird at the sanctuary, its food supply also being supplemented by surrounding garden feeders.


Great tit (Parus major)

  The great tit is the largest of the UK tits. It shares the blue tit's bright yellow belly and breast, but its black crown meets at the throat and descends its front in a vertical stripe. The cheeks are white. It was often seen in the company of other tits and small birds at the sanctuary.

Long-tailed tit (Aegithalus caudatus)


  The long tailed tit is a familiar sight in the sanctuary's woodland. As the name suggests, it has an elongated tail that looks too long for such a small bird; a bird that can match any of the small and cuddly mammals on the cute scale. The long-tailed tit makes an incredible nest from natural materials such as: lichen, moss, and spider's webs. Having come across one that was old and discarded, it feels like an elasticised ball, which they usually furnish with feathers. In the front is a small hole through which they come and go when feeding their young.

Dunnock (Prunella modularis)

  Another small bird is the dunnock. Often seen on the ground near hedges, it feeds on insects and seeds. It is distinguishable from other small brown birds by its grey head and chest, which seems to emphasise a brown patch around the eye.


Goldcrest (Regulus regulus)

  The goldcrest is one of the UK's smallest birds, and one of the most distinctive when close enough to see its bright gold cap. This is the only one I have seen in and around the sanctuary, it can be mistaken for the very similar firecrest. Its brightly coloured crown is surprisingly difficult to make out at distance. They usually feed on spiders and insects.

Treecreeper (Certhia familaris)

  Finding a treecreeper can be tricky...until it moves. I have often found myself staring at the bark of a tree, certain that some movement has drawn my attention there. The treecreepers' mottled brown back blends perfectly against the tree, camouflaging it against unwanted interest. When it does move, you can usually catch sight of its lighter coloured breast and belly as it scuttles around the tree in an upward spiral, pulling out
insects and spiders from the bark with its ideally curved bill.

Nuthatch (Sitta europaea)

  Unlike the upwardly mobile treecreeper, the nuthatch will work the tree in any direction. A fantastic looking bird, with a bluish grey back, an orangey buff front, white throat, and a black superhero mask over the eyes. It has a strong bill which it uses to extract insects from the bark, and its occasional tapping can often draw you to the bird's presence before it has been seen.



  They also feed on nuts and seed, particularly sunflower seeds, which will attract them to garden feeders. Their powerful bills mean they are likely to dominate the feeders from other small birds.


Great spotted woodpecker (Dendrocopos major)

  Louder, constant drilling means there are woodpeckers present in the wood. There have been sightings of the green woodpecker at the sanctuary, but I am yet to see one. The great spotted woodpecker is resident, though, and is usually heard before being seen. It is quite a sight when they finally come into view: their distinctive black and white feathers being brightened by a brilliant flash of red. The bills are incredibly strong, and the motion as they hit the wood is something of a blur. 


  The strength of its bill means that the great spotted woodpecker dominates the local garden feeders. When in attendance, small birds must feed quickly or face the potentially fatal consequences of its swiftly stabbing bill.

Spotted flycatcher (Muscicapa striata)

  Through the summer, I saw numerous spotted flycatchers hanging-out near the river. Visitors during the traditionally warmer, lighter months, this particular bird was perched on a riverside branch, biding its time before leaping for unsuspecting insects. It did not seem too bothered by my presence.

  That March provided some of the nicest weather of the year, says a lot about 2012. It rained. And then it rained some more. Save for a week or so in July, and occasional August hours, the rain continued throughout the ironic summer. When it didn't fall, it threatened, covering the sky with an oppressive grey. Storms in May and June caused significant flooding and damage to the surrounding area. Trees came down, while the riverbanks crumbled and washed away under the pressure of unrelenting water; all at a time when the wildlife was preparing for a new generation. Yet the drama of the devastation was nothing compared to the spectacular sight of revival, as the following calm was met with a flurry of activity. I was completely anonymous, utterly inconsequential, as the birds set about rebuilding their nests and lives. It was something to see.

Wren (Troglodytes troglodytes)

  With insects being abundant along the rivers, the wren can usually be seen feasting nearby. One of the smallest birds - just a little larger than the goldcrest - its white stripe above the eye, and wing line that resembles a pleated skirt, make it unmistakable. However, from a distance it can resemble many other small brown birds. 



Grey wagtail (Motacilla cinerea)




  It is somewhat ironic that the most prominent and memorable colour of the grey wagtail is yellow (the yellow wagtail is even more yellow and is not usually seen as far west as the sanctuary). There are several pairs of grey wagtails living along the local rivers. When standing, they share the seemingly nervous tail-wagging characteristic of all wagtails, but they are far from nervous around water, where they spend most of their lives, nesting in banks and feeding off the ample supply of insects.

White-throated dipper (Cinclus cinclus)

    The white-throated dipper is another frequent sight along the rivers, and can even be seen submerged beneath the water surface in search of freshwater shrimp. It gets its name from the way it repeatedly squats
while standing. It has an amazing capacity to navigate through the tight twists and turns of narrow rivers and streams, and avoid unforeseen obstacles at speed. While travelling along the river, it seemingly skims along the surface.

Grey heron (Ardea cinerea)

  The grey heron is perhaps the best indicator that the local rivers hold healthy stocks of fish, which they eat  in abundance. They will also feed on small birds and mammals, as well as amphibians, of which there is also plenty. An imposing sight, the adult grey heron can stand over three feet tall, with long legs and neck, and an orangey dagger-like bill. Its eyes are yellow. This remarkable bird looks even more impressive flying through the narrow channels of the Nant Llech river.

Cormorant (Phalacrocorax carbo)


  The cormorant is another large bird that utilises the local resources. Generally dark with a lighter coloured chest, it has a hook on the end of a long bill. A great underwater swimmer, it is the pest of fishermen everywhere, who simply cannot compete with its natural ability to catch fish.

Goosander (Mergus merganser)

  While the mallard is a permanent presence at the Sanctuary, the goosander duck is an occasional visitor to the surrounding rivers. They dive for fish, slicing through their prey with their razor bills.

Black headed gull (Chroicocephalus ridibundus)

  There are a few gulls that hang around the Sanctuary, the most obvious being the black headed gull. In the summer its head is dark, and actually more brown than black. It can be seen here in its winter look. Another  opportunist eater that thrives wherever morsels of food are left behind.

Magpie (Pica pica)

  Magpies are a familiar sight just about anywhere in the UK, and the sanctuary is no different. Belonging to the corvid family, they are distinctively black and white, with a subtle greenish-blue sheen. Their size is extended considerably by the length of the tail. The magpie is omnivorous and appears content to turn most organic matter into a meal, which is probably a reason why it is such a successful species.

Jay (Garrulus glandius)

Jay peering from behind a branch

  In contrast, the jay seems a much shier corvid, whose appearances at the sanctuary have been largely restricted to the surrounding woodland verges, from which it will fly soon after being spotted. Much more colourful than the other corvids, it has a brown back and a striking flash of blue on its wing. Just about in shot here is its impressive black moustache. Jays share the corvid appetite for eggs, small birds and small mammals, but much of their diet consists of fruit, seeds, nuts and insects, with a particular fondness for acorns.

Jackdaw (Corvus monedula)


  Flocks of jackdaws are a daily sight at the sanctuary, congregating in trees and foraging the open fields for insects and worms. Like other corvids, their adaptable eating habits are part of their success. They are an impressive sight when roosting, as hundreds take to the evening air, casting vast swirling shapes against the darkening sky. From a distance, they can be difficult to distinguish from other corvids, whose territories they often share, but they are smaller than the carrion crow, with pale eyes, and a silvery sheen to their crown.

Carrion crow (Corvus corone)

  Unlike the jackdaw, the carrion crow is much more solitary, and rarely seen in anything more than a pair. The below crow was half of one such couple, but was in no mood to share its food. Only when it had finished did it allow its partner to come near.

   

  The carrion crows are strong birds and can be quite fearless in the face of larger birds. During the summer, in the sanctuary's sky, one such crow - perhaps with nearby young - insistently saw off the attention and intention of a persistent red kite.

Red kite (Milvus milvus)

  The red kite is one of the UK's great conservation success stories, having recovered from only a few birds to an estimated 1,000 breeding pairs in Wales alone (rspb.org.uk). Its forked tail makes it unmistakable in flight, as it soars across the sky with minimal movement to its wings. They will eat small birds and mammals, as well as eggs, but much of their food is carrion. They will also eat worms.

Sparrowhawk (Accipiter nisus)

  Given the prevalence of small birds, it is not surprising to find a presence of sparrowhawks in and around the sanctuary. Seeing them is another matter however, as much of their time is spent in the surrounding woodland.

Common buzzard (Buteo buteo)

  The common buzzard is another familiar sight in the skies above the Sanctuary, and occasionally as a flock, circling the air.



  Photographed below is a particularly white common buzzard, which initially made it more difficult to identify. It was taken a little further down the River Tawe, hovering high in the air, before suddenly narrowing its body and dropping from the sky like a bullet.


  There are doubtless numerous birds at the sanctuary that I have not recognised or been able to identify. Warblers are a notable absence, being a member of those small brown birds that can be difficult to tell apart. I will take a closer look at all the sanctuary's birds through 2013, and attempt to photograph the fascinating and beautiful kingfisher, that flies up and down the Tawe's verges.
