Three of us went out to the Hunting Hollow entrance area at Coe SP to do a survey for the California Breeding Bird Atlas project. There was modest breeding activity detected and we got a few expected confirmations.
Of extreme interest was a pair of Pileated Woodpeckers well seen at the parking lot at around 6:30AM. They were clearly and closely interacting. It would be great to confirm this species breeding in the Diablo Range as this would indicate a significant range expansion.
Also of interest was a pair of Lawrence’s Goldfinches engaged in courtship behavior. Many singing Song Sparrows were along Coyote Creek; when we first started visiting this area many years ago this species was completely absent. Also, several Black-throated Grey Warblers were observed singing in the area.
