Gull rings at the Eirol landfill, Portugal, September 3 2013


A waste of time at the landfill? Between 7:00 – 11:30 there were about 3250 Lesser Black-backed Gulls that visited the site. I highly suspect that the amount of exposed and delivered garbage has become a limiting factor for gull numbers. Only 23 rings were read this morning, which were applied in Guernsey (13), The Netherlands (3), Great Britain (4; excluding Guernsey), France (1), Norway (1) and Spain (1; Larus audouinii).







Larus audouinii







The only ring I could find among 550+ White Storks (bird in the middle). A dirty metal ring, placed on a tarsus.
