I'm blogging this as I've never seen the likes before and confirms how clever/clued up the adults birds are here. Today I had't to venture over the water and had thoughts of dropping into the fish quay for a while this afternoon. At first this Juv. Glaucous gull sat rested on one of the shed roofs here, before eventually dropping down to join the feeding frenzy of mainly immature Herring and Great-black backed gulls in the gut.
This bird bossed its way to the front of the by-catch throw out-as expected
Did a few nice fly-byes in the gut
Followed the bird onto the river side of the quay- wasn't long before 'wiser' eyes made this birds efforts in vain.
