Chough - 2002 preliminary results of ringing

This article attempts to summarise some of the findings emerging from a Pembrokeshire Ornithological Research Committee (PORC) Chough Study Group project, to examine post-fledging dispersal, survivorship and recruitment of choughs to the local breeding population.
