Dettagli dell'osservazione
Very surprised to see these were Greater Scaup; massive raft; best estimate by block count x100; examination of photos show all birds in images have rounded head (no indication of rear peak of Lesser Scaup) and in flight, white in upper wings extends from secondaries across primaries; poor record photos show these features. May have been some other species mixed in but everything we looked at and in photos were Greater Scaup.
