Status summary

Collared Dove abundance has increased rapidly since the species first colonised Britain in 1955. From just four birds in 1955, the population was put conservatively at 15,000-25,000 pairs by 1970 (Hudson 1972). The CBC index showed an almost exponential rise as colonisation continued during the early 1970s, but had levelled off by about 1980. BBS shows continuing increases, at least in England. The changes in breeding performance per nesting attempt have been very slight improvements.
