[EBB Sightings] Cassin's, Costa's, and MacGillivray's

Birders,

A pair of CASSIN'S KINGBIRDS continue at their nest in the power tower 
nearest the Alameda/San Joaquin county line along Tesla/Corral Hollow 
Road. When one kingbird dropped a bit of nesting material the other 
caught it in mid-air and took it to the nest. A LARK SPARROW flew 
across the road nearby.

A COSTA'S HUMMINGBIRD was perched atop a tree at the entrance to Kiln 
Canyon at Carnegie State Vehicular Recreation Area (CSVRA). In the 
canyon we had RUFOUS-CROWNED SPARROW (including one juvenile), 
MACGILLIVRAY'S WARBLER, WILSON'S WARBLER, ORANGE-CROWNED WARBLER, 
HERMIT WARBLER, NASHVILLE WARBLER, RUFOUS HUMMINGBIRD, ANNA'S 
HUMMINGBIRD (no Calliope or Allen's), CANYON WREN, BLACK-HEADED 
GROSBEAK, and ASH-THROATED FLYCATCHER. We spent the better part of an 
hour getting decent views of the MacGillivray's Warbler (maybe 2) that 
sang from dense cover. On exiting the canyon we saw our first of 
several WESTERN KINGBIRDS. Pairs of BULLOCK'S ORIOLES and WARBLING 
VIREOS were at the east end of the park where we also saw another 
Costa's Hummingbird and a Wilson's Warbler.

A ROCK WREN sang from a hillside fence on the opposite side of Corral 
Hollow Rd from the large rock outcropping a couple of miles east of 
CSVRA.
