Chestnut-collared, Tropical, Lucy's, Yellow-headeds
Various CBC compilers have or will post results from the local CBCs as to what was seen and approximately where. Here's some additional info on a few of the "better" birds I've seen the past several days:
Chestnut-collared Longspur [not on a CBC]: One of the two birds seen by Gary Nunn at Fiesta Island on 7 Dec was a full adult male in winter plumage--complete with much blackish to the underparts, a buffy tinge to the face, and a mostly chestnut collar. It was seen again both yesterday (Turley) and today (Lehman), 27th and 28th, in the northern section of the dog run. Either with Horned Larks or at least loosely associated with some larks. And the McCown's Longspur continued somewhere in the dog run yesterday as well.
Lucy's Warbler: continuing bird at upper San Dieguito Park in Rancho Santa Fe continues as of yesterday. See my post on 22 Dec, discovery day, for further info. Almost all sightings of the bird have been between 8:30-9:30 AM along the east (sunny) edge (main parking lot edge) of the large tipu tree patch. One problem finding the bird is that it is often fairly sneaky, no doubt the result of it being harassed by Yellow-rumpeds. There is also a Black-thr. Gray Warbler there.
Tropical Kingbird: the bird found by Tito Gonzalez in s. Carlsbad on 23 Dec was still present on 27 Dec for the Oceanside CBC. It frequents along Seascape Drive near and at the corner with Camino de las Ondas, often frequenting the sweet gum, or sycamore, trees along the road--with 7:00-8:30AM being the preferred time. Present off and on. Also two imm. male Bullock's Orioles here.
Yellow-headed Blackbird: I had 2 birds, an obvious adult male and a non-descript imm/female, in with a mid-sized flock of Starlings, Red-wingeds, and Cowbirds feeding in the ag fields along Calzada del Bosque in Rancho Santa Fe, the site of the wintering Sandhill Crane way back in 2008-2009. Very rare in winter.
