Last weekend myself and three others from Norfolk joined Paul Roper and the North Thames Gull Group for a day out cannon netting gulls on a rubbish tip, nice!
With a cold morning the birds were clearly hungry so soon after the net was set and a recent delivery of household waste in place we took a catch of mainly Black-headed Gulls which did include a Polish ringed Med Gull.
This bird was already ringed, bearing a Polish metal ring and a red colour ring. This is only the 24th Polish Mediterranean Gull found in the UK and only the second in Essex (the first was seen at Southend in 2006).
After extractions a small team reset the net and took another catch of 179 composed mainly of Herring Gull. A total catch of 587 was good experience in catching gulls in this situation and training ringers to age larger gulls.
