I started at the Modoc Preserve and nearby spots. Best birds were a female Bullock's Oriole at Modoc Rd/Las Palmas, and a female-type Summer Tanager along Cieneguitas Creek near Modoc Rd.
The Page Youth Center was a bust. The tipu trees that were good for warblers have been removed. I couldn't find any sparrow flocks there nor at the nearby cemetery.
I went through all the tipus in the car park of the Goleta Valley Medical Building where I saw 2 Lucy's Warblers on Monday. I didn't see them, nor did I see anything else interesting.
Presumably the same Yellow Warbler has returned for another winter in the willows at the eastern corner of the Bird Refuge.
