Rain, heavy at times and easing up through the night. Sigh.
There was a nice south wind, so anxious birds braved the weather and picked their way north. Not in great numbers but fairly widespread as the weather would allow. It’s tough to pick them out between the rain cells so we have the Hydrometeor loop today to aide in finding the birds; a little like finding Waldo.
American White Pelicans have been reported in the region, a few more Western Kingbirds and Osprey as well. Ruby-crowned Kinglets are starting to sing. It’s a wonderful song and we only get a small window in early spring to hear it before they clear the area as they head north to the breeding grounds.
Pacific Slope Flycatcher reported in the Central Valley is a first arrival.
A very rainy weekend — again. It cleared up late Saturday night but too late for any birds of significant numbers to move north.
But, last night was clear and there was an accommodating south wind so the birds were on the move. We’re still at the beginning of the migration so we are not getting “green doughnuts” but we do have some 20+ dBZ returns.
In the Central Valley more Western Kingbirds are being reported as well as Common Yellowthroats. In the Portland area Violet-green Swallows, Rufus Hummingbirds, Osprey and an increasing number of shorebirds. I observed over sixty Greater Yellowlegs, a few L.B. Dowitchers and a large flock of peeps (unidentified) on the wing this weekend.
The Central and Mississippi Flyways were also pretty active last night. National Composite Radar is included thanks to Paul
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.
