Black and White

Oystercatcher

Cormorant
Two birds that are black and white and are more traditionally thought of as coastal birds.

The Oystercatcher is a bird that is found along our coastline during the winter months, but has started to move inland to breed, where it nests on river banks, the shores of lakes and gravel pits. A bird that does not eat or catch oysters, but instead it feeds on mussels and cockles at the coast and worms inland. The population of this bird has been slowly growing during the last 50 years, although in the 1970`s it was `culled` in South Wales to protect the commercial cockle industry (this has now, thankfully stopped) and has a breeding population of around 30-40,000 pairs.

The Cormorant in the photo above looks to be of the european race sinensis which has started to colonise Eastern Britain due to the white patches on the crown and upper neck. Another bird whose fortunes are linked to commercial fishing interests, with calls being made for the bird to be `culled` due to its liking for eating fish. Whilst Cormorants undoubtedly take fish, long-term damage to commercial fish stocks has not been proven and the bird remains protected, although if fisheries can prove damage is being done they can apply for a license to shoot a limited number of these birds. The population is around 12,000 pairs.

Not everything in nature is black and white.

Cormorant




Digiscoped using Canon Powershot A640 and Kowa TSN-883 x30



There is something primeval about the Cormorant, something Pterodactyl-like.

A large bird, the size of a large goose, it has come into conflict with commercial fishing interests due to its` fondness for eating fish and there have been calls for their numbers to be controlled.

The population in Britain and Ireland is thought to be around 12,000 pairs, with some coastal colonies declining, but inland colonies appear to be increasing. Outside of Britain and Ireland these birds breed across Scandinavia, Europe, Russia, China, India, parts of Africa, New Zealand, Australia, Iceland and a few birds even breed in North America.
