The Blackpoll Warbler was still at Zzyzx on Weds, the 27th.
On Thursday, there were 5 Red-naped Sapsuckers (RNSA) at Crystal
Spring, including 4 in one small tree. One of the sapsuckers had an
all-white throat, but in all other respects resembled a female RNSA.
Horse Thief Springs had an Ovenbird, American Redstart, and my first
junco of the year, a Pink-sided. There was also a Blackpoll Warbler
in Shoshone. On Friday, a Northern Waterthrush was at Furnace Creek
in Death Valley, and an American Redstart was at Scotty's Castle.
There were also 8 RNSA at Scotty's, including one that at first
glance appeared to be a Yellow-bellied Sapsucker (YBSA) in an
unusually advanced stage of molt. The barring on the back was well-
spread, and had the characteristic dingy brownish yellow color of
YBSA. The nape appeared to lack any red, but at 40X in the scope, I
could see a slight hint of red at the periphery of the nape.
Combined with the fact that the broad border to the throat was
infiltrated with red, I'd say the bird was a YBSA x RNSA hybrid. On
Sat, the 30th, there were 3 Bobolinks at Furnace Creek. Today, the
Wood Thrush was still at Crystal Spring. A Western Scrub-Jay
(Woodhouse) was at Beck Spring. An Indigo Bunting and 16 Greater
White-fronted Geese were at the Baker ponds. Lastly, a Tennessee
Warbler was in the last large tamarisk tree before the trail to the
springs at Zzyzx.
