TUALATIN RIVER NWR FALL-OUT

April 23, Sunday

Today we had our fourth and final field trip for the McMinnville Parks’ spring birding class.  Our birding karma was at its peak.  Last night brought in a large shipment of migrants, chiefly Vaux’s Swifts and Yellow-rumped Warblers.  The latter were a mix of both myrtle and Audubon’s in their vibrant spring fashions.  In addition we watched  a pair of Spotted Sandpipers go through some courtly courtship ritual right below the visitors center viewing area. The only other shorebirds were a small, dense cluster of nervous Least Sandpipers.  Next we saw a Peregrine harassing a harrier.  The Peregrine in turn attacked by a female Kestrel.  These were all feints, no damage done.  We did not see the BT Gray nor Wilson’s Warbler others reported nor hear either rail species (Va and Sora) but still came away with a fine morning’ s list, a closing salute  from a rattling Kingfisher and got into our cars just as the rain hit.

AS we reached the restoration oak grove on the trail, there were warblers all around and that continued until we reached the dense forest along the river:AUD-WA FLIZAUD-WA1AUD-WA2AUD-WA3AUD-WA4AUD-WA5

Here’s one of the Spotted Sandpipers:S-S1S-S2S-S3
