Led by Denise Wight. This abbreviated version of a Contra Costa County Big Day is a great way to discover the habitats and birds this East Bay county has to offer. Denise, a Contra Costa County native who has been teaching and leading birding classes since 1993, is the perfect guide! The trip will begin in Tilden Park, move to the Albany and Richmond shoreline, then, head east to check out Martinez and Mitchell Canyon on the north side of Mount Diablo. The day will finish in East Contra Costa, where we will have a chance to see some Central Valley birds. This will be a day of great diversity in one of the most exciting counties to bird in our region. Visit Denise’s website at www.blkittiwake.com.
