Two new ponds close to the observatory buildings.

Observations: Gyrfalcon: A 2cy took a Herring Gull in the fields west of the station in the morning, then sat on the prey through the whole day. Lots of Black-headed Gulls feeding in the surf at Reve kai in the afternoon. We were able to read 10 colourringed birds among then, including JN92 that was ringed as a chick in Risavika a little further north in June 2014.

JN92, first adult plumage. 

Most Black-headed Gulls from the Stavanger-area spend the winter in the UK, most in Scotland. If anyone has sightet Black-headed Gulls with green or whote colour-rings with a code starting with the letter "J", then they are of Norwegian origin and please report them here: http://www.ringmerking.no/cr/
