Wildlife to see in September 2015

The seasonal colours should make attractive photographs and there is an abundance of possible subjects, says Chris Chappell.

Autumn colours are already starting to show in the trees and shrubs, encouraged by the somewhat unseasonal weather in August. There are generous crops of berries in the hedgerows. Elder, rowan, guelder rose, spindle and hawthorn all adding colour while providing ready food for birds. Blackberries also hang heavy on the brambles, a popular snack for field and dormice, as well as birds.

And as summer draws to an end, September sees most of our summer migrant birds head south, and the start of the inward migration of our winter visitors. Bird migration is an immensely complex subject, driven by the need for food, breeding grounds and suitable climate for survival. Primarily birds are heading south to avoid the cold winter. Ospreys stop off for a week or two, as they travel from the north down to the West African coast. Ducks and waders are arriving from their breeding grounds in the north. The whistling of wigeon, and the cry of the teal are a characteristic background soundtrack to a visit to the flooded levels. In addition to the arrival of birds seen only during the winter, our native populations of many resident birds are swollen by overseas visitors of many species, from be it goldcrests, starlings or short-eared-owls. Blackbirds and robins travel from Northern Europe to take advantage of our milder climate.


Late butterflies and dragonflies

Plenty of butterflies and dragonflies are still on the wing in September. Look for common darters, an abundant small dragonfly, the male is bright red and the female olive green. Many of the damselfly species are on the wing now, as well as the various large hawkers, Southern, migrant, brown and common. These are spectacular brightly coloured creatures, and can be quite obliging, landing nearby, or even on your clothing.

The pretty clouded yellow butterfly has again made the long migration from Africa, and can be seen mixed with the common white butterflies, flitting across a meadow on sunny days. Brimstone, comma, common blue, red admiral and small copper butterflies may still be seen on warm September days. The extraordinary hummingbird hawk moth has made a good showing this year, and may stay on the wing right through to November. Looking and sounding like a hummingbird, the body vertical during feeding on the wing, its long proboscis probing flowers, buddleia a big favourite, as with many insects.

Birds Flocking

As the breeding season ends, many small birds will gather in large flocks. Greenfinches, goldfinches and chaffinches will chatter noisily in the tops of trees, relying on safety in numbers and many keen eyes to spot an approaching predator.

Starlings begin to assemble in the towns and villages each evening, then set off to roost en masse, performing their spectacular patterns in the sky, now known as murmurations. Strictly speaking the murmur is of course the sound, as thousands of birds wings whir across the landscape. If you are out on the levels when a flock passes overhead, you will hear something quite unique, a great whisper across the land. As the birds approach their roost, they will swirl and gyrate in amazing patterns, settling, rising again, and moving across the reedbeds like running water. Their movement in the air is often driven by the appearance of a sparrowhawk or other raptor, hoping to pick off an easy meal. Once settled they start to chatter, rising into a crescendo of calls that may last some long time. While this phenomenon has been filmed and recorded, this cannot convey the full sense of awe that this spectacle inspires if you are actually there.

Corvids also now flock and feed together, and a freshly turned field may attract a mixture of carrion crows, rooks, jackdaws and the occasional raven. They work their way across the fields, picking up worms and beetles as they go.

Shoreline Waders

The Severn Estuary and the Bristol Channel, fed by the River Parrett estuary and the Huntspill Sluice, provide the perfect environment for many wading and dabbling birds. In addition to the reserve at Steart Point, there is now the new Steart Marshes project. This will be a key area in the Southwest for waders, something we are very lucky to have in the county. Huge flocks of small waders, can be seen on the extensive mudflats: oystercatcher, dunlin, ringed plover grey plover, turnstone, sanderling, along with larger birds, such as curlew and black tailed godwits. They make an impressive sight when they take flight, changing colour as they turn in the sun. Large numbers of shelduck can be seen on the shores and sandbanks, a bulky, distinctive duck in white with green neck and chestnut front, and a bright red bill. They probe the mud for small crustaceans, snails and invertebrates. Many rarer waders complete the mix, such as ruff, or little ringed plover, but you do require some good optics to see them. In addition, birds such as whinchat and wheatear may be found on the tide-line, feeding up on flies before they cross the Channel heading south. The best time to arrive is just after high tide, as the birds will fly in as the mudflats are exposed by the receding water.

SWT Catcott

Catcott reserve is relatively quiet during the summer, as the main attraction has always revolved around the wintering ducks and waders that arrive when the Lows are flooded. However, the newly restored area (The Fen) just to the south, now has reed beds which have attracted summer visitors reed and sedge warblers this summer, and our resident Cetti's warbler and reed bunting.. And slightly delayed, there is now an impressive new tower hide. From here you can see marsh harriers hunting. These are rare and spectacular birds and a delight to watch as they turn and weave, looking for prey. Peregrine, kestrel and buzzard are also regular visitors. The hobby, a small raptor with the same moustache-like facial patterning as a peregrine, will soon leave for Africa. Once a rare sight, this summer breeding falcon now breeds across England and Wales. In flight it looks quite like a large swift, with curved wings and darting flight. Roe deer regularly browse on the fringes of the reserve, happy to feed in sight, but always at a good distance from the nearest human.

Photography

This is a good time to get out with your camera, as the trees start to change colour, and misty mornings and the low morning and evening sun add to the atmosphere. Dew covered cobwebs stretched between plants make great close-ups. Horse chestnut trees are already turning rusty yellow, to be followed by ash, beech and sweet chestnut. Ivy is one of the last plants to flower and the black berries are an important source of nectar for wasps and bees, whose populations swell as autumn progresses. The wild clematis flowers are turning from shiny green curls to the woolly 'Old man's Beard', running along the hedgerows. Another great subject for close-up photos.
