Birds of Conservation Concern 4: the Red List of Birds
winter bird surveys
Bird ringing is an essential element to the understanding of birds because the number of birds ringed generates information on the survival, productivity and movements of birds, helping us to understand why populations are changing.
Although, we have been bird surveying and ringing in Britain and Ireland for over 100 years, we are still discovering new facts about migration routes, breeding and wintering areas.
The Breeding Bird Survey is a nationwide survey supported by the British Trust for Ornithology (BTO), Joint Nature Conservation Committee (JNCC) and the Royal Society for the Protection of Birds (RSPB). As well as monitoring the population of birds, this survey also serves as a way of assessing the overall health of the countryside in general.
Direct from Scandinavia, the walled City of York welcomes flocks of Waxwings (Bombycilla garrulous). Up to several thousand Waxwings have arrived this autumn and can be clearly identified by the bright red tips on their plumage, square-ended yellow tail feathers and a black band running across their eyes.
