A little bit of Maridalen

Back for a few days in Oslo I paid my first trip in a while to Maridalen. The hot weather we have had most of this spring and summer seems to have resulted in a very good breeding season for Swallows (låvesvale) and White Wagtails (linerle) with many youngsters to be seen. A single Common Rosefinch (rosenfink) showed itself and two singing Lesser Redpolls (brunsisik) are an indication of breeding which would be the first time here. I saw a single beaver and more disturbingly a family of mink which showed no fear of me – will it be ever possible to get rid of this disastrous introduced species?

Five adult Black-throated Divers (storlom) together on the lake were probably a group of failed breeders but a Red-throated Diver (smålom) that flew off with a fish is most likely breeding nearby.

Signs of a good breeding season can also be seen in the garden where broods of Greenfinch, Tree Sparrow, House Sparrow, Blue Tit, Great Tit and Fieldfare were being fed by parents today.
