Diablo Foothills Regional Park Trailhead Parking

Pine Canyon

Pine Canyon, which includes the Castle Rock EBRPD recreational area, and the Diablo Foothills Regional Park just beyond, provides rich habitat and resources for spring migrants passing through, as well as for many returning and nesting summer residents.

We should expect to find nesting pairs of Bullock’s Orioles and House Wrens. Warbling Vireos, along with their cousins, the Cassin’s Vireo, nest within the canyon. Rufous-crowned Sparrows are to be found, and if we’re lucky, Lazuli Bunting. We’ll look (and listen) for Black-headed Grosbeaks and Western Tanagers. Western Wood-Pewees and Pacific-slope Flycatchers pass through. We might get lucky with an Olive-sided Flycatcher. And the warblers: breeding plumage Yellow-rumped, Black-throated Gray, Wilson’s, Yellow, Nashville, MacGillivray’s, Hermit, Orange-crowned, and Townsend’s.

Bring water and snacks. This should be a wonderful springtime field trip.
