WHEATEAR Oenanthe oenanthe
 
Conservation Listings Long term trend

Unlisted/Green
Biodiversity Steering Group Conservation Concern List

UK: Uncertain, possible decline
 
Status Summary
Although common, the Wheatear was not monitored adequately until the inception of the BBS because of its habitat preferences. Gibbons et al. (1993) identified range contractions from lowland Britain, perhaps due to losses of grassland and declines in rabbit abundance. Breeding performance tends to have increased over time (failure rates at the chick stage (18 days, comprising 14 days incubation + 4 days laying) have fallen from 27% in 1975 to 13% in 1998). The BBS shows no clear trend in abundance since 1994.
