London's wildlife: More than pigeons

No bird is more talked about in London than ring-necked parakeet

Beneath a backdrop of rollercoasters, a handful of ducks dive for fish in an ice-free wedge of the gravel pit. The location – Thorpe Park – may be incongruous, but these wildfowl are worth it. They are smew, a stylish "sawbill", and south-west London forms the heart of their British wintering grounds. What finer Christmas present for a capital weekend of urban wildlife?

Fewer than 200 smew typically winter in Britain. The drake is a "designer duck", with a minimalist colour scheme of black eye-mask and slashes on a snow-white background, topped off with a punky crest.

Then sally east to Staines reservoirs, walking the causeway bissecting two concrete basins. Using a telescope, scan the apparently deserted waterscapes to reveal a profusion of waterfowl. Pochard and tufted duck may secrete in their midst goldeneye or even scaup. Great crested grebe is plentiful, but Staines is also a prime winter site for the dinky black-necked grebe.

End the day at nearby Staines Moor. Search for water pipit and little egret alongside pools and the River Colne (plus goosander on the latter). Look for a sentinel stonechat, a red fox stalking, a common buzzard soaring or a red kite gliding.

Start day two with the capital's most statuesque mammals. Take advantage of the late dawn to arrive at Richmond Park for first light. The mist shrouds herds of red and fallow deer. Then venture towards central London. In Barnes, WWT London Wetland Centre has hosted a remarkable habitat transformation, whereby four defunct reservoirs were replaced with a complex of reed beds, marshy grassland, open water and carr. Numerous ducks – notably gadwall, wigeon and shoveler – graze the marshes, and a jack snipe may bob like a clockwork toy beside the plentiful common snipe. Peregrines often streak overhead and a drowsy water vole may emerge.

There's a final urban treat in store. No bird is more talked about in London than ring-necked parakeet. These avian aliens have definitively landed, with 30,000 now domiciled in South-east England. So spend dusk watching the central copse at Wormwood Scrubs local nature reserve. Up to 5,000 birds sleep here, making the trees look like they have a fresh set of leaves.
