Re: Where are the Lake Merritt Scaup?

According to Birds of the World:
Lesser Scaup spring departures can start mid February.
Their migrations are really spread out.
Greater Scaup are usually thought to start moving north in March,
but there's some question about starting to migrate north in mid February.
While day length is a big driver,
maybe there are food quality issues this year????

What a great question, as I have noticed the same. The huge scaup flock was on the lake earlier this winter but seems to have disappeared not long after New Years. Normally you can find decent number of scaups farther into the winter, in fact I distinctly remember seeing some as late as May last year. Weirdly though I also have not seen scaup in large numbers at some of my regular shoreline sites in recent weeks either (Arrowhead Marsh and Middle Harbor). There were hundreds at Arrowhead earlier this winter and no more. Where did they go??
