Herring Gull

Through September 2010 I have ringed 172 Herring Gulls. These birds were ringed as bycatch throughout the country, but most in Amsterdam and Groningen. For most of the birds a sample was taken for the avian influenza virus.

In the city of Groningen some Herring Gulls were colour ringed wth a white colour ring around the tibia. This in order to establish the duration of stay in the city. The codes used are: H+, J+ and K+. The administration of these colour rings around the tibia is done by E-mail: . More info see: http://buijsecoconsult.blogspot.com.

For all of the ringed Herring Gulls I have received one remarkable recapture. Arnhem 5460058, ringed on December 17th 20009 as a 4th calender year in Nijmegen and is read on April 4th and 5th by Eddie Fritze at the refuse tip at Riga in Latvia.
