12 September 2016 – PNW Migration Update

Migrants are feeling the call south.  With winds out of the east, probably from temperature differentials, the cross winds did not slow the birds down last night.  The upper left hand corner was jammed with southbound sojourners.

The first Cackling Geese are being seen, wintering pink-footed gulls are pushing into the valley and more early Golden-crowned Sparrows are popping up here and there.

While there was light movement last night most of it was obscured by clouds.  So we’ll take a look at the Hydrometeor Classification Loop so we can pick out the biological returns. (brick reddish signal)

On the ground; reports for Fox, Golden-crowned and Lincoln Sparrows, Hermit and Varied Thrushes, and the continued passage of shorebirds.  So far it’s been an unusual season — lots of birds moving through but at a low, but consistent pace.
