An adult Kumlien’s Gull was in a mixed flock at the rivermouth at 10:30, before flying inland up the river. It wasn’t subsequently relocated, but obviously could still be around.

I returned shortly after and digiscoped what appears to be a Yellow-legged Gull. The mantle appears a little on the dark side, but it otherwise looks good for that species – size, structure, open wing tip pattern, nice chrome-yellow legs etc.
