NSAS’s April Field Trip to Mount Diablo’s Mitchell Canyon, Thursday, April 23rd at 8:00 a.m. – with Bruce Thomsen & Mark Stephenson

This is the perfect time of year to view Mt. Diablo’s Migrants and Resident Birds. Deer Flat Creek is flowing from Spring showers and the canyon is resounding with bird song. Resident Anna’s and migrating Calliope Hummingbirds are feeding on spring flowers and males can be heard zipping down from hundreds of feet up in their display flights hoping to impress a mate. Acorn, Nuttall’s & Downy Woodpeckers are actively chiseling out nests. Olive-sided, Western and Ash-throated Flycatchers are setting up territories and Hammond’s are passing though on their way to the Sierras. Hutton’s and Warbling Vireos will be actively starting nest building. Warblers including our resident Orange-crowned and Wilson’s will be singing along riparian corridors and Yellow-rumped, Nashville, Black-throated Gray along with an occasional Hermit will be feeding in the trees tops. In the higher chaparral we expect to find CA Thrashers, Rufous-crowned and Bell’s Sparrows. There is a $6.00 Parking Fee that requires cash or check.

Detailed Information and Registration sign-ups will be sent out about a month before the trip.
