White-fronted Geese at the New Grounds, 1946-47 to 1963-64

Abstract

The White-fronted Geese, Anser a. albifrons, wintering at the New Grounds, Slimbridge, Gloucestershire, have probably been counted more regularly and for a longer period of years than any other comparable flock of geese in Britain. Counts at frequent, often daily, intervals have been made for the past eighteen years. These figures are examined below for changes or trends in the numbers and seasonal behaviour of the birds.
