Oslo islands

With just 2 DAYS TO GO UNTIL VÆRØY 2017 begins I thought I would get some practice for island birding in today with a trip to Oslo’s own rarity (un)filled islands. I took the public boat and had an hour each on Gressholmen, Lindøya and Nakholmen.

Passerine wise I guess I have vague hopes of one finding something along the lines of a Yellow-browed Warbler, Richard’s Pipit or Little Bunting out here one autumn but more realistically I can hope to see some waders. My Oslo list still lacks the likes of Little Stint, Curlew Sandpiper, Turnstone and Grey Plover and it these islands that offer the best chance of encountering these species (which are far less than annual).

Today’s trip did not deliver any of the sought after rare passerines but a Wheatear and a few Chiffchaffs and Blackcaps were enough to keep me looking for more. Waders were not exactly numerous either but a juvenile Knot showed well (it was only last year I added this species to my Oslo list) and three flyover Ruff were only my fourth Oslo record. But surprisingly there were no other waders what so ever.

A couple of seals were hauled up and one showed well. These were Common/Harbour Seals and both this species and Grey Seal seems to be becoming far commoner in the Oslo Fjord.

Knot (polarsnipe) a rare species in Oslo 

overflying Ruff (brushane)
a resting Seal (steinkobbe)

and another Seal. This one looks to be a young animal
over 130 Cormorants (storskarv) were resting on Galteskjær but I didnæt have a shag today - not so far anyway...;-)

my first auk of any kind in Oslo this year - a Guillemot (lomvi)
