2000 National Census of Pink-footed Geese and Icelandic Greylag Geese in Britain & Ireland
(2000)
A Report to JNCC
The 41st consecutive census of Pink-footed Geese and Icelandic Greylag Geese took place in Britain and Ireland during autumn and early winter 2000. Two discrete counts were undertaken and coverage of sites was good. Both counts were carried out under favourable weather conditions. Maxima of 242,419 Pink-footed Geese and 81,097 Greylag Geese were recorded in October and November, respectively. When adjusted to account for major sites that were not counted and numbers of UK Greylag Geese, population estimates of 245,349 Pink-Footed Geese and 80,324 Greylag Geese were derived. Both population estimates are greater than those calculated in 1999, although not directly comparable because the methods used to derive the adjusted population estimates are new. The Pink-footed Goose estimate represents an increase of 15.5% over the 1999 peak count and the Greylag Goose estimate an increase of 5.8%. Both species had a more successful breeding season than average: Pink-footed Goose flocks contained 18.7% young and mean brood size was 2.15 goslings per successful pair and Greylag Goose flocks contained 20.9% young and mean brood size was 2.48 goslings per successful pair. The average proportion of young between 1990-99 was 17.6% in Pink-footed Geese flocks and 16.7% in Icelandic Greylag Geese.
