"Upper" Santa Ana River-still a few latish migrants (Nov. 1)
- Nothing much of significance, but while birding Saturday (Nov. 1)
from the Santa Ana River biketrail, in the City of Orange
(downstream of the Glassell crossing), noted a few latish migrants.
Just southwest of Glassell there were two Ash-throated Flycatchers,
together (one was at this same spot last week); also here was a lone
Northern Rough-winged Swallow. Further downstream was a Yellow
Warbler and a Western Tanager, which I'm presuming were migrants, as
not typical habitat for wintering inidividuals of these species.
Just downstream of Lincoln (in the River Trail community) were 2
Black-throated Gray Warblers. At the nearby Burris Basin (where very
low water levels are now forming isolated, shallow pools) was an
impressive concentration of "piscivorous" birds catching the trapped
fish. The largest concentration, at the south end of the basin,
contained about 250 "white egrets" (Snowies and Greats), dozens of
Great Blues, upwards of 500 Double-crested Cormorants, 150 American
White Pelicans, and small numbers of grebes, gulls and terns.
Nothing unexpected for the area, however. A single Peregrine Falcon
was perched nearby watching the action.
