UK: Uncertain, possible decline
 
Status Summary
The Whinchat's preferred habitats were not covered well by BTO surveys before the advent of the BBS, which shows no clear temporal trend since 1994. There has also been no clear trend in breeding performance except for an increase in average clutch size. However, Gibbons et al. (1993) identified a range contraction from lowland England that was probably due to the loss of marginal farmland habitats.
