It is a patterned black and buff colour and blends in well in its only habitat, wet reed beds. It skulks about in the reeds, catching fish with a stabbing motion.
Bitterns grow to between 69 cm and 81 cm in length, have a 100 cm to 130 cm wingspan and weigh up to 1.94 kg.
The male is black with a yellow ring around the eyes and a yellow beak, the female is brown, which makes it very easy for a change to tell them apart.
The Common Blackbird is omnivorous, so eats a wide range of insects, earthworms, seeds and berries.
Species: T. merula
The Blackcap, Sylvia atricapilla, is a common and widespread sylviid warbler and breeds throughout temperate Europe, western Asia and northern Africa. Blackcaps in northern Europe tend to migrate to southern Europe or North Africa for the winter, those in southern Europe tend to stay put.
The Blackcap has a greyish body and, as the name suggests, a distinctive black cap. Having said that, the female has a brown cap, making the male and female easily distinguishable. Its closest living relative is the Garden Warbler.
Insects are its main diet although it will eat berries if there are not enough bugs around which makes it quite a hardy bird.
Species: S. atricapilla
The adult male is basically dark grey to black on the upper parts with a black breast and an orange-red lower rump and tail with the two central tail feathers dark red-brown. The belly and undertail are a blackish-grey.
The female is grey overall except for the orange-red lower rump and tail.
Species: P. ochruros
In summer they have a bright orangey chest, belly, neck and head, in winter they’re more greyish-brown. Female black-tailed godwits are bigger and heavier than the males and have a longer beak.
They measures around 42 centimetres from bill to tail with a wingspan of 70–82 centimetres. Males weigh around 280 grams and females around 340 grams.
Godwits dine mainly on invertebrates and the odd aquatic plant, although in the breeding season their diet may also include beetles, flies, grasshoppers, dragonflies, mayflies, caterpillars and molluscs with the occasional meal of fish eggs, frogspawn and tadpoles.
Species: L. limosa
The Blue Tit prefers insects, caterpillars and spiders for their diet, although outside the breeding season they also eat seeds and other vegetable-based foods.
The Blue Tit is usually about 12 centimetres in length, has a wingspan of around 18 centimetres and weighs in at about 11 grams.
The common Blue Tit has an azure blue crown with a dark blue line passing through the eye, encircling the white cheeks to the chin. The forehead and a bar on the wing are white. The nape, wings and tail are blue, the back is yellowish green and the under parts are mostly yellowy with a dark line down the abdomen. The bill is black and the legs bluish grey. Both sexes are pretty similar and juveniles are noticeably more yellow.
The yellowness of the belly is apparently indicative of the number of yellowy-green caterpillars eaten (due to high levels of carotene pigments).
Species: C. caeruleus
The adult has a plain greyish-green back, greenish rump and wings and whitish underparts. The bill is small and pointed and the legs are brown. As with most warblers, the sexes are identical.
It eats insects.
Species: P. bonelli
It has a black head and neck and grey-brown back, and either a pale or dark belly depending on the race. Adults have a small white neck patch. The rump is and the tail is black and very short.
Brent Geese eat vegetation, particularly grasses.
Species: B. bernicla
The male Bullfinch has a bright pinkish-red breast and cheeks, grey back, black cap and tail, and bright white rump. The female has a greyish chest.
Woodlands and hedgerows are a good place to find Bullfinches. They eat buds of fruit trees, seeds and, during the breeding season, insects.
Species: P. pyrrhula
The Buzzard grows to a length of between 40 cm and 58 cm, has a wingspan ranging from 109 cm to 136 cm and can weigh up to around 364 grams.
It has a broad, rounded wings and a short neck and tail. Birds are variable in colour from all dark brown to much paler variations but all have dark wingtips and a finely barred tail.
Species: B. buteo
