* In my analysis of ringing recoveries I am greatly indebted to the Ringing and Migration Committee of the British Trust for Ornithology for permission to examine all the recoveries of Hen Harriers ringed in Britain and Ireland, and those ringed abroad and recovered in Britain (none of the latter have been found in Ireland).

† Two chicks, illegally taken from a brood in North Wales, were ringed and ‘hacked back’ in Anglesey, and released on 14 and 19 July 1973. The first was found shot on 29 July near Oswestry, Shropshire (100 km ESE) and the second was ‘shot’ on an unspecified date in August near Basingstoke, Hampshire (290 km ESE).

* Since this was written, R. C. Dickson has seen a ringtail with a white wing-tag at a roost in Galloway on 24 October 1976. Nick Picozzi tells me that this bird must have been tagged as an adult, by him, in Orkney during the summer of 1975.

* Recoveries up to and including August of the year hatched are excluded from the tables as some may have been of birds which never fledged and others are certain to be of birds still dependent on their parents. I have also excluded any in which the circumstances of the recovery made it impossible to judge whether the bird was first year or older. Birds recovered up to August of the year after hatching are counted as first year.
