Just a quick update - I dashed that out quickly...

Correction...the only clear non-Surf Scoter was a White Winged Scoter on wing...

Pretty amazing...the whole ~350 bird raft would dive together...the birds at the front leading edge would dive, slowly followed by others...it took ~30 seconds for the rest of the raft to dive. Hard to imagine there was that much prey below...but there you have it.

A real highlight catching this group!
