My new found caution with this species pair left me initially to hum and ha. The buffeting of the breeze (ha, ha), the distance and the brevity of the view didn't help but it had to be an Iceland Gull.
We then contemplated a walk and I went around the back of the car to hold the door whilst Louise got the waterproofs out. Open door, Louise flails as waterproofs get out all on their own and head rapidly in a gangly, airwalk towards the ocean. Subsequent good fielding by Louise recovered two pairs and slightly mad wave dodging on the beach below the cliff captured the last unruly legs.
