Adult
Brent geese and their chicks. The families are very close and stay together
at least until the following breeding season. Young of the year can be
recognized by the white rims of the feathers on the back. This enables us to
establish the breeding success of the preceding season by counting the
number of adults and young on the wintering grounds. The proportion of first
year birds in the winter of 2005/6 appeared to be about 40%, very high
indeed!

The majority of the Brent geese got an individual ring-combination of two
colours and two characters.
This
one reads as: ‘Green J Blue A’.
