Birds
Well over 100 bird species can be found within the park during the year, with about 60 of them being UK residents and the rest being seasonal migrants. A list of most of our birds can be found at the end of this page.
Raptors
The two raptors most likely to be seen in the valley are Buzzards and Kestrels, both of which are residents that nest in the valley, along with Sparrowhawks. You may also see migrants, such as Hobbies or the occasional Marsh Harrier.
Buzzard

Often seen wheeling high in the sky, singly or in groups, or perched on a tree or fence post.
Kestrel

Smaller than the buzzard, kestrels can often be seen hovering, almost motionless, as they hunt for mice or voles.
Marsh Harrier

Flood meadows and reedbeds are ideal habitat for this fairly frequent winter visitor.
Water Birds
Some of the water birds are the largest birds in the valley and the easiest to spot. Most of those shown below can be seen in the valley throughout the year. The last three are sea birds that are frequently found on inland waters.
Mute Swan

Lots of swans can be found on the lakes and streams and several pairs raise broods of cygnets.
Greylag Goose

Parties of Greylag Geese fly into the valley for the winter and some stay all year round and breed. Often seen on the flood meadows.
Canada Goose

A few Canada Geese are usually found associating with the Greylag Geese, although lately there have been large flocks.
Grey Heron

Herons can be found in the valley all year and can often be seen patiently fishing at the edge of pools.
Little Egret

Slightly smaller than a heron and with pure white plumage, the Little Egret is now a fairly common sight in the valley.
Mallard

The most familiar of our ducks, the Mallard is to be found throughout the park.
Coot

These are very common on all the lakes in the valley.
Moorhen

Not so numerous as the Coot in the valley, but often seen around the margins of open water.
Tufted Duck

These distinctive little ducks are more frequently seen during the winter months.
Black-headed Gull

Flocks of these are often found on the larger lakes. In winter their heads turn white with just a black spot either side.
Herring Gull

Flocks of Herring Gulls are also a common sight on the lakes throughout the year.
Cormorant

This large seabird can often be seen on the larger lakes in the park. Many Cormorants roost in a tree by the Pebsham lake.
Land Birds
Many of this group of birds are hard to spot, unless you can recognise their call, as they tend to skulk around in trees or undergrowth. A few are shown below.
Blackbird

A familiar garden bird, the Blackbird can be found in woods and hedgerows.
Blue Tit

Another familiar garden bird. The Great Tit is also fairly common.
Carrion Crow

Often seen in the fields or perched on fence posts.
Chaffinch

The Chaffinch is fairly common and the male is brightly coloured.
Goldfinch

Flocks of Goldfinches are seen in the valley and are unmistakable with their red face and yellow wing flashes.
Lapwing

These are mainly winter visitors when more than a hundred can be seen on the flood meadows. Very few stay and attempt to breed.
Long-tailed Tit

A gregarious bird that is usually seen in small flocks.
Magpie

A conspicuous member of the crow family that can be seen all over the valley.
Pheasant

Often heard calling, there are quite a lot of Pheasant resident in the valley.
Reed Bunting

A wetland bird, these are usually found along the rivers or in the reedbeds.
Reed Warbler

Another summer visitor whose insistant warbling can be heard in the reeds.
Robin

Probably our most recognisable bird, the Robin is common throughout the park.
Sedge Warbler

Often heard in the reeds, but less often seen, the Sedge Warbler is a summer visitor.
Stonechat

The male has an orange breast and distinctive black head. Resident but more often seen in the summer.
Swallow

A summer visitor, often seen skimming over the lakes or reeds feeding on insects.
Treecreeper

A woodland bird that can sometimes be seen hunting insects on tree trunks.
Wren

One of our smallest birds, the wren is very shy and flits around in the undergrowth.
Yellowhammer

The male yellowhammer is unmistakable and likes to sing from the top of a bush.
