The first few weeks in the life of a Herring Gull
14 December 2010
in the summer of 2010 two Herring gulls built a nest on the roof of our neighbours’ house. We watched in amazement as they hatched their chicks and we watched them grow over the coming weeks until the finally learnt to fly.
Now, in 2015, that gull is still alive, as the Witte Weekblad paper in Leiden city of 26 August reported.
Gull Green F.AMA (called so because of the colour of, and the letters on, her ring) is often at the Leiden market for fish and cheese scraps.
Sometimes, she is in Katwijk as well.
USA: The western gull may seem common, but because these gulls hybridize frequently with glaucous-winged gulls, there are areas of their range where hybrids outnumber the population of pure-blooded birds. At one time the yellow-legged gull was also lumped with the western gull as a single species. Birders who know how to distinguish these gulls, however, will be thrilled to add such a distinctive, elegant bird to their life lists: here.
