You can add one more name to the list of locations that is mind-blowingly crawling with migrants right now: the west basin of Kumeyaay Lake in Mission Trails Regional Park.
I hiked around the west basin on the circuit trail that goes around it, and in 50 minutes (7:50 - 8:40 a.m. Sat. morning) came up with the following:
8 species of warblers:
Black-thr. Gray (5-6)
Wilson’s (at least 12-15)
Nashville (1) (I didn’t get a great view, but it definitely had an eye-ring, white on the belly, and a yellow throat.)
Yellow (1 male seen, 2 heard)
C. Yellowthroat (several heard in the reeds)
3, maybe 4, species of Vireos:
Bell’s (at least 2 heard calling)
Hutton’s (1 that was bug-snarfing right in front of me at eye level. Also possibly a 2nd one calling.)
Maybe a Plumbeous, but not positive. It had a big eye-ring and wing-bars, but wouldn’t cooperate.
Also along the circuit trail:
Western Wood-pewee (very close and cooperative)
As well as all the usual suspects.
Plus, the cherry on the sundae as I was leaving the lake area: a Least Bittern flew across the pond.
No orioles or Swainson’s Thrushes.
And, now for the mystery bird of the day: High in a tree, so I only got an underside view, a thrush size and shape bird, including thrush-type bill, with a white breast with heavy dark vertical streaking, white belly. Yeah, I know, you’re saying “hermit”. So was I except for one thing: it had very distinct white (maybe better termed very light gray) outer tail feathers, as seen from below. (Other tail feathers were grayish-brown underneath.) Could a HETH ever show this kind of tail feather plumage? And if not, other suggestions? The bird was definitely larger that a sparrow, with perhaps a somewhat longer tail. Thanks for any ideas.
