This morning’s focus will be “birding by ear” – finding and identifying birds based on their vocalizations. This is a great time to focus on the voices of our year-round residents before most of our migratory breeding birds return and fill the forests with an exuberant chorus of song. There are just a handful of these common birds which overwinter and breed here, but many of these species have a wide range of vocalizations so becoming familiar with these now can make the later spring choir easier to unravel. With luck we may get a head start on some early returning migrants as well, such as orange-crowned warblers, pacific slope flycatchers and warbling vireos. This walk is for adults. We request that no animals (except service animals) attend. Heavy rain may cancel. If questionable weather, call (415) 893-9527 on the morning of the walk for a recorded message to see if the walk is cancelled. Shannon Burke will lead. Questions: Contact Shannon Burke at (415) 893-9520 or SBurke@marincounty.org. Meet at the gate at the end of Cascade Dr. DIRECTIONS: From Hwy 101 in Larkspur, take the Sir Francis Drake Blvd exit west to Fairfax. In downtown Fairfax, drive about 0.4 mile west on Bolinas Rd and make a soft right at Cascade Dr (at the stop sign). Continue about 1.5 miles to the gate (dead end). Parking is limited.
