Well, The birds have been picking their way north for a few weeks now, but because of the nearly constant rain it has been damned hard to pick them out of the radar noise. Even the HC was not reliably designating biological returns.
Last night however, once the rain moved through, we got a decent migration signature. On today’s loop, wait for the rain to pass and you will see the flight — up into the 20 dBZ range.
Tree and Violet-green Swallows as well as Turkey Vultures have made it to the Portland area. Even Barn Swallows are being reported in Clallam County in Washington. Western Kingbirds are in the Central Valley in California as well. Waterfowl numbers are down a bit too.
