Today, August 21 2013, during a morning visit to the Eirol landfill near Aveiro, Portugal, 36 gull-rings were read. The number of gulls was still relatively low, I suspect about 6500, including about 6100 Lesser Black-backed Gulls, 400 Yellow-legged Gulls and only a few Black-headed Gulls. The number of white storks was impressive: well over 1000 took off and left the site around noon.
The only colour-ringed Yellow-legged Gull observed today.
Probably the first recorded Audouin's Gull Ichthyaetus audouinii in Eirol
In between foraging trips, the birds sleep, take a bath, preen their feathers or read a magazine
Dirty, but readable ring. One of many from Paul Veron (Guernsey)
These are not gulls, but White Storks
Around noon it became too hot for me and the gulls. Only a few hundred were still present when I left the site.
