Species Not included -
Carrion Crow, Magpie, Jay, Grey Squirrel, "Domestic" Cat, Mink, Heron, Buzzard, Red Kite, Sparrow Hawk, Cormorant, Greater Spotted Woodpecker, Hobby, Peregrine Falcon, Goshawk.
It has been mooted that many of the declining species are a) Insectivorous, b) ground nesters
It should also be noted that some of the others are c) migratory or d) reliant on holes in trees for nest sites.
The depletion in insect life is very valid IMHO - this has (or should have been linked ) to the flailing of hedgerows and the "Neatness fetish" which destroys nettles and long grass in verges - precisely at the time when some species (Grey Partidge for instance) need to be nesting in that environmet. [Grey partridge chicks are also insectivorous in their early lives ! ]
However - Some noticeable omissions - Cuckoos for instance are less easy to explain - except for the lack of their (insectivorous) hosts ! |
