British Birds: Some Decline While Others Increase….

July 17, 2008

In an earlier posting we noted that one species (Great Tits) of British birds was coping quite well with alleged climate warming. A report today in The Independent (U.K.) shows that, while many British birds are declining in numbers, others are increasing. Causative factors in decline included intensification of agriculture causing loss of farmland birds such as grey partridge and corn bunting; changing woodland management methods, increased deer populations, predation by grey squirrels, and problems on wintering grounds in Africa of migratory species as causes of declines in woodland birds. (willow tit -77%, wood warbler -67% etc).

Changes in vegetative undergrowth caused by deer browsing is listed as the most likely factor in the decline of woodland birds. The nation is seeing a rapid increase in deer population led by the muntjac, an introduced tropical deer.

The good news, however, is reserved for the so called garden variety birds: many are exhibiting substantial increases in numbers probably due to backyard feeding and warmer winters: (oh, oh there’s that climate warming bugaboo again!) great tit +55%, goldfinch +39%.
