Tues 24 April 2012 – PNW Migration Update

Locally, it appears migration continues apace.  We had a moderate amount of birds in the air last night with a pulse or two of heavy movement.  Cloud build up over the Cascades and some thunderstorms on the east side kept migration mainly up the I5 corridor.

In the field: reports continue to trickle in — Western Kingbirds, Warbling Vireos, first Lazuli Bunting and more of the already reported warblers and flycatchers.  Some of the peeps are being seen in choice spots as well.

Regionally things were just like here.  A slight lessening of the intensity but steady moderate flights with a few pulses of heavy migration.

Nationally the strong north winds and weather associated with the low pressure system hanging out back east kept the Atlantic and Mississippi flyways under lock-down.  A small high pressure ridge stuck it’s nose into the western gulf and provided some southerly flows and really put the southern half of the Central Flyway into high gear.  Some cross winds had to be contended with north of Texas but seemed to be navigated quite well.  The Southwest is enjoying migration pulses as well — it’s about as good as it gets down there right now.
