Gull Update

David,

Thank you for reporting your sightings of colour ringed Gulls.

They are birds which were colour-ringed ringed at Harewood Whin landfill site, to the west of York, (53.960 -1.177). The birds were caught using a Cannon Net and are some of around 1750 Gulls which have been caught and colour ringed to date.

Harewood Whin is one of the decreasing number of Landfill sites in the UK where it is possible to operate for the catching and ringing of gulls. Whilst with us the gulls feed on the Landfill site during the day and roost on the floods in Lower Derwent Valley National Nature Reserve or on the Humber Estuary.

Individual details of the birds are given below.

I hope you find this of interest and many thanks for taking the time to report your sightings.

Best Regards

Mike Jackson
