Comments:
Tom Wurster and Liga Auzins Wurster. 44 - 67 F, clear, variable cold breeze blowing down canyon 2-10 mph; near calm in wind protected zone immediately below cottonwood grove. By 7:45 wind dropped to 1-2 mph throughout. 20 minutes burst of migrants starting 7:00 AM, otherwise just a trickle of migrants. Cottonwoods & tree of heaven leafed out; air filled with cottonwood "lint". Coverage: spring area, parking area including tree of heaven grove and peach thorn flats; leisurely late morning walk down canyon about 1/2 mile and return. Venus, a very thin crescent in binocs, shined like a beacon at dawn, low in the east.

Olive-sided Flycatcher

This is the earliest spring date listed in ebird for the eastern Kern desert region. Earliest date in Matt Heindel's manuscript is 21 April.Our FOS. Calling "quick 3 beers" and flycatching from tops of trees of heaven. Kingbird size flycatcher, large "triangular" head; dark brown olive above, white thru midline of underparts, sides densely streaked olive; very long wing projection.

Hammond's Flycatcher
3
Gray Flycatcher

2 w/ typically longish billed with dark tip to lower mandible and classic tail drop action; However, the bird photographed gave me fits - the bill doesn't look long enough in photo (but visually appeared longer in other poses), and I can only see a hint of its yellowish base, and bill appears characteristically "thinner/flatter" rather than thicker/rounded as in Dusky). In the end,its repeated downward tail drop action outweighed my doubts.

Repeatedly dropped tail down, then up. Loud whit call note

1
Dusky Flycatcher

Whit call eliminates Hammond's; repeated upward tail flicks eliminate Gray. Body proportions and color very similar to Gray, but colors more clouded (duskier, not cleaner gray); bill shorter (and thicker?) than Gray.
