Today the government reported that in spite of some recent recovery of wild bird populations, their numbers are shockingly dropping off. Seabirds have maintained their populations above the levels measured in the 1970’s. However, farmland birds have failed to keep their populations above what they were in the 1960’s, save for one slight spike in the middle of the 70’s.
Alterations to habitats, which destroyed grounds for feeding and nesting, were the fault for farmland bird population plummets. However, the 40% drop in woodland species is a mystery to the RSPB.
The British Trust for Ornithology consider intense agricultural land usage has targeted the birds who depend on the moorland and wet grasslands. Reduction of vegetative covering, more intense drainage at neighbouring farmlands, overgrazing by deer, and the winter climate alterations are all thought to factor into the gradual disappearance of woodland birds.
While the overall population of woodland birds is plummeting, certain species are on the increase, such as the jackdaw and wood pigeon doubling, as well as the greenfinch and stock dove growing by 50%. Others are being hit hard, such as the willow tit, lesser spotted woodpecker, wood warbler, tawny owl, blackbird, bunnock, and the song thrush.
Wetland and water birds have remained fairly stable since numbers were consistently watched in the 1970’s. Those birds who live in still or slow moving waters have increased their populations by 73%, while those of the wet grasslands have dropped of by 56%. The birds of the faster flowing waters have only seen a 17% reduction in their populations.
