I’m not seeing any neo-tropical migrant news except maybe a Western Kingbird in the Central Valley (CA).
But birds are on the move, not “Green Doughnut” type, but a decent movement up the valley reaching 20 dBZ in patches. Also a pretty steady flow up the I5 corridor in Washington. Probably re-positioning from Ridgefield to Nisqually,
Cliff Swallows have made it to Oregon, but not much else.
A decent movement up the valley was noticeable last night, and that was into the wind. So, the urge is building. Since we’re not getting reports of spring migrants these probably continue to be waterfowl re-positioning and staging for the push north.
I looked at the Seattle radar (ATX) and there wasn’t any noticeable movement.

Update: Cool composite radar from last night! Note the bloom in Southern Georgia (Moody AFB, GA (KVAX)) and how the weather band puts the birds down.
