Crow Question

stevensi

I was in England at the weekend and noticed they have a lot of carrion crows and it got me wondering why they are fairly rare over here. I know we get a lot of hooded crows in Ireland which are rare in England. Is there some reason for the difference in the species between the two countries?

Cheers

The Hooded Crow is the same species as the Carrion Crow but is a different race, and is mostly found in Ireland, Scotland and the Isle of Man. It's just a matter of distribution as happens with many Species and Sub-species of birds and animals.

Ireland also has very -comparatively- poor biodiversity.

I thought Corvus corone and Corvus cornix were discovered seperate species at the moment...

You are right to an extent. Their subspecies status was indicated by Corvus [corone] cornix.
On 17th September 2002, the British Ornithologists' Union decided that Hooded Crow was a species in its own right. Generally it has long been regarded as a sub-species of the Carrion Crow Corvus corone largely because there is a wide range of intergradation between the Hooded and Carrion Crows where they meet which is in Scotland roughly in line with the Great Glen, and in western Europe from Denmark south to northern Italy.
Bottom line I suppose for the OP is that each fills the same niche in their respecteive zones.

Care to elaborate?
