Estimates of the British population of Common Kestrel Falco tinnunculus suggest a continuing decline in the past 30 years, from around 100,000 pairs in the early 1970s to little more than a third of that level in the early years of this millennium. This paper summarises recent survey work in several English counties which questions recent estimates of Common Kestrel breeding density. It is suggested that the current British population remains above 50,000 territorial pairs and that, although there has been a steep decline in some parts of its range, the Common Kestrel still breeds at high density (50+ pairs per hectad) in mixed farmland in much of England.
