Daniel,

The cormorants are probably moving to follow the herring spawn that’s occurring in the bay. A group of 11 just flew over corona Hill about 20 minutes ago.

About 10 minutes later had a lifer yard bird, American Goldfinch (actually 2 landed in our bare tree). It was the bold contrasting wing bar pattern that caught my attention and flight calls that confirmed it. Those calls, by the way, came from the 2 birds communicating in unison with other AMGOs also heading SE. There were about 20 Spinus sp. in 2 flocks, maybe all Americans but I would guess others might have interloped.
