Glad to help: danieledelstein@att.net

Early arrivals in 2019 so far in Marin County (first county north of the Golden Gate Bridge in the SF Bay Area) and where many of my birding tours occur (along with Sonoma Co., a county north of Marin Co.):

- Black-headed Grosbeak (about 2 weeks earlier than most years, if this individual was a true migrant and NOT an over-wintering aberrant)

- Wilson's Warbler (heard in February this year; earlier than some years)

- Grasshopper Sparrow (~3/18 by a Sonoma Co. birder....I noticed my first ones on 3/24 and 3/25/19 at Mt. Burdell in Novato....near where I live.)

Regards, Daniel
