Cormorant
These prehistoric-looking fisherman have become an increasingly common sight along inland lakes and waterways in the UK.
It is now widely acknowledged that large numbers of cormorants, naturally coastal-breeding seabirds, are establishing colonies across the Midlands and East Anglia.
This is good news for inland ornithologists, but anglers are concerned that the cormorants' exceptional fishing ability will finish off already depleted fish stocks.
Cormorants are surprisingly large birds. Some say that their long necks and hooked bills give them a primitive, almost reptilian appearance. This is enhanced by the fact that they are commonly seen standing atop rocks, posts or trees with their wings out-stretched to either side. The cormorants' oily plumage is only partially waterproof and after diving for fish, they effectively have to hang their wings out to dry.
The last 30 years have seen a substantial increase in the total number of cormorants found on UK coasts, estuaries, lakes, rivers and gravel pits. They are now frequently seen in central and eastern areas including the Yorkshire coast, Norfolk, Cambridge and Essex.
