WHEATEAR

Conservation listings

Europe: no SPEC category, secure
UK: Green

Long-term trend
UK: possible decline
Status summary
Although common in many upland areas, the Wheatear was not monitored until the inception of the BBS in 1994. Gibbons et al. (1993) had by then identified range contractions from lowland Britain, perhaps due to losses of grassland and declines in rabbit abundance. The BBS shows wide fluctuations but no clear trend in abundance since 1994 in either England, Scotland or Wales. Failure rates at the egg stage (18 days, comprising 14 days incubation and 4 days laying) have fallen, but so has brood size.
