Abstract
A slow but steady increase in Sparrowhawk numbers has brought the species to a level where CBC monitoring has become practical; but numbers are still rather low, so that values for annual changes have wide confidence limits. 1962-1974 data are too few for index calculations, but an indication of the overall trend can be obtained from the annual proportion of CBC plots recording Sparrowhawks.This publication has 3 references indexed in Scilit:
