BLACK-HEADED GULL
The largest ever recorded flock of Black-headed Gulls in the
county was a huge 20,000 birds roosting on Audenshaw Reservoirs on the
5th November 1978.
An interesting observation, one of the first ever observed of
this unusual behaviour, was of several birds feeding on elderberries by hovering
and picking them off at Hindley on the 17th October 1976.
Black-headed Gulls can live to a ripe old age and an adult
bird ringed in Hindley on 21st of June 1976 was still alive and well in Griend,
Netherlands on the 30th May 2000, aged 21 years old!
There are many interesting ringing recoveries of this species
in the county, going some way to informing us of just where our winter influxes
