Status Summary
Although the breeding population is not monitored annually by the BTO, its distribution has spread inland, especially in England, probably associated with the increase in number of gravel pits and reservoirs (Gibbons et al. 1993). The recent marked trend towards increasing nest failures at the egg stage is potentially worrying and warrants further investigation. The failure rate for the 27-day egg stage (24 days for incubation + 3 days for laying) has increased from 55% to 71%.
