Hi all,

Below are the tallies from this morning's run of the Umpqua Breeding
Bird Survey route, which traverses some of the best/most extensive
remaining grassland bird habitat in western Oregon. 

A highlight was finding GRASSHOPPER SPARROWS at 3 locations, with a
total of five singing males. Finding a pair of ASH-THROATED FLYCATCHERS
near a possible nest site was also fun, as were the abundant WESTERN
MEADOWLARKS and WESTERN KINGBIRDS.

A lowlight was finding only two VESPER SPARROWS -- my lowest count in
three years of running this count.

The biggest surprise of the route was, at the very last stop in Driver
Valley, to hear HERMIT THRUSH singing from up a slope in a fairly mature
Douglas-fir plantation. 

This was just a couple of miles from where I heard two of the
Grasshopper Sparrows and one of the Vesper Sparrows. I'm guessing that
not many BBS routes in Oregon have recorded Red-shouldered Hawk, Hermit
Thrush, and Grasshopper Sparrow all on the same five-stop data sheet.

Happy birding,
Joel
