I managed to quite easily pick out the Caspian Gull in flight which raises the possibility of IDing one on a seawatch in the future.
Moving back into Oslo I failed to find any interesting gulls which I had hoped the recent storm “Nina” may have pushed up into the inner Oslofjord. Water had been pushed in though and the sea was a good 2 metres higher than normal. The Botanical Gardens were also devoid of interest with a single Hawfinch and a singing Goldfinch the highlights (the fact it was singing rather than the species).
First a video of the Caspian Gull where it calls a couple of times. Some say they can pick out this species just on call. I lack the experience to do that. Here it is giving a short call rather than the “long call” when they throw there head back but I definitely wouldn’t be able to pick one out just on this call.
