As a freelance Consulting Biologist (who is also a Certified Wildlife Biologist Asc.) based in Marin County (San Francisco Bay Area), Daniel Edelstein works full-time in the environmental consulting field. Possessing survey permits for rare species — the state and federally endangered Ridgway’s Rail (formerly California Clapper Rail); the state and federally threatened California Tiger Salamander; and the federally threatened California Red-legged Frog, — his role as a full-time staff and freelance Avian Biologist & Wildlife Biologist since 1998 are niches by which he conducts field surveys for common and rare bird, mammal, amphibian, reptile, and plant species — in addition to providing clients regulatory and permitting services relating to local, state, and federal regulatory measures (e.g., to name a few: local heritage tree ordinances that vary by city; procedures required via the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA); and federal laws such as the Migratory Bird Treaty Act (MBTA) that protect nesting bird species, typically from February 1 through August 31, annually)

He also specializes in songbird and raptor nest search and monitoring surveys, including recent and current bird survey and bird monitoring projects in 1) Brentwood, CA (SF Bay Area) where an active heron rookery requires him to conduct surveys and management solutions to ensure compliance with California Department of Fish & Wildlife (CDFW) codes and the federal Migratory Bird Protection Act (MBTA) — both of which protect nesting birds; 2) Lake County (CA) along Walker Ridge Road where a proposed wind turbine array required two years of bird surveys (including autumn migratory raptor surveys) along a 10-mile route; 3) Mendocino County (CA), where Daniel performed bird nest searching surveys at a Caltrans project: “The Willits Bypass Project”; 4) several locations where Daniel coordinates Moffitt’s Canada Goose management planning, nest finding, and egg addling (see below); and 5) Pre-construction bird surveys and follow-up compliance reports to ensure clients are able to obtain permits as they comply with CDFW codes and the MBTA that both protect nesting bird species.

Follow-up compliance reports and wildlife/plant management plans are submitted to public agencies, planning departments, consulting firms, and landowners/stakeholders. His wildlife survey background features bird point counts, nest searching, and nest monitoring (especially at proposed wind power sites and other energy pipeline routes), in addition to mammal trapping, tracking, tape playback (owl species such as Northern Spotted Owl), pit-fall/drift fence surveys (California Tiger Salamander), and dip-netting/seining (fairy shrimp surveys).

1200px-Kanadagans_Branta_canadensisAddressing Moffitt’s Canada Goose overpopulation problems for agencies (often sanitary districts) is another niche Daniel performs, whereby an Integrated Goose Management plan and other short- and long-term management techniques are implemented — including: a) habitat alteration (Daniel designs and implements a native species planting plan, for example); b) barricade additions (e.g., boulders/fences); and c) non-lethal goose overpopulation control actions, including egg addling (after he secures a federal permit).

Recent projects have also included helping neighborhood groups and individuals — e.g., Preserve Ross Valley, Save San Marin, and Mendocino County homeowners — contest development projects to protect their wildlife, solitude, and dark skies, via Daniel writing reports to ensure projects complied with local, state, and federal regulatory measures.

Concurrently, Daniel (a professional birding guide since 1986) leads San Francisco birding tours and northern California birding tours (including Marin County birding tours and Sonoma County birding tours), in addition to other California bird watching trips.  As a featured Birding Guide at GuidedBirdWatching.com, he has presented his adult birding classes, bird slide shows and birding by ear and raptor identification field training workshops in more than 20 states.

As a northern California birding guide and community college birding instructor Daniel teaches periodic diverse college-level bird/environmental classes {in the Biology Department at both Diablo Valley College (San Ramon) and Merritt College (Oakland)}: Fundamentals of Ornithology; Bird Song Ecology/Birding By Ear; Raptors; Wood-Warblers on the West Coast (& Midwest/East Coast); The Miracle of Migration: The Amazing Nomadic Lives of Birds & Other Animals, and Nature Study & Conservation.

(His student birdwatchers visit diverse San Francisco Bay Area birding hotspots in San Francisco, Berkeley, Oakland, and Marin County cities. See below.)

MacGillivrays Warbler Known for his 30+ years of watching and studying wood-warblers (Parulidae family), Daniel’s popular Warbler Watch blog and warbler tips ID chart offer fast relief for birders seeking warbler identification help (including solutions for identifying confusing fall warblers). Recurring seasonal land and sky events (i.e., phenology) are highlighted at Daniel’s homemade Nature Watch Calendar that includes monthly planet-rising times, meteor shower dates, and annual eclipses.

In addition to San Francisco birding places that attract rare San Francisco birds, destinations for Daniel’s birding trips include Point Reyes National Seashore (and its Point Reyes Lighthouse area) and many other prime-time California birding spots such as Bodega Bay, Bodega Head, Doran Park, Muir Woods, Bolinas Lagoon, Tomales Bay State Park, Las Gallinas Wildlife Ponds, Elkhorn Slough, Golden Gate Park, Yuba Pass, Sierra Valley, Hawk Hill, Mines Road, Del Puerto Canyon, Mount Diablo, Lake Merritt, Lake Merced, and Palo Alto Baylands.

Black-throated Gray WarblerUncommon to rare species that he helps birders find include Northern Spotted Owl, California Black Rail, Ridgway’s Rail, Yellow Rail, Marbled Murrelet, Western Snowy Plover, and California Condor, in addition to area specialties such as Swainson’s Hawk, Northern Pygmy Owl, Northern Saw-whet Owl,  Hermit Warbler, Yellow-Breasted Chat, Nuttall’s Woodpecker, Brown Pelican, Brant, Cassin’s Vireo, Rock Wren, Lawrence’s Goldfinch, Tricolored Blackbird, Lewis’ Woodpecker, California Thrasher, Sooty Grouse, and Bank Swallow.

A Few Of Daniel’s Other Recent & Ongoing Projects: 1) Conduct focused wildlife/bird surveys as a permitted biologist for Ridgway’s Rail (formerly CA Clapper Rail), California Red-leggd Frog, and California Tiger Salamander. (For example, my focused surveys for Ridgway’s Rail occur annually from January 15 through April 15.) 2) Research, write, and submit compliance reports (e.g., Biological Assessment, Initial Study, EIR biological resources chapter, habitat restoration plan, etc.) as a Consulting Biologist on behalf of clients such as environmental consulting firms, sanitary/water districts, vineyards, landowners, and other stakeholders. 3) Serve as birding guide for one-day or multiple day birding trips in San Francisco Bay and other California locations for individuals and groups that contact me: danieledelstein@att.net (click on the Birding Tours tab, above). 4) Teach periodic bird-related classes to adult students at Merritt College in Oakland, CA (including my upcoming “Fundamental Of Ornithology And Birding In Central CA” class 9/18 – 10/30/18. 5) Conduct pre-construction bird surveys and nest search surveys to help safeguard nesting songbird and raptor species.

Birding Guide (summary)As a freelance Avian Ecologist/Consulting Biologist and experienced San Francisco Bay Area birding guide, I also occasionally lead other California birding trips to the Sierra Nevada Mountains (e.g., Yuba Pass, Gold Lakes, Sierra Valley area) and many other California birding hotspots, such as Pinnacles National Park where I help birders enjoy seeing the majestic California Condor. Among the guided birding tours in California I offer, many of them visit Important Bird Areas (IBAs). In total, think of me primarily as a veteran birding guide in Marin County and, in addition, a specialist who leads to birding outings in Sonoma County, in addition to regularly leading guided birding trips elsewhere in California and the Midwest — the latter of which includes teaching periodically at The Ridges Sanctuary in Baileys Harbor, WI (ridgessanctuary.org), in addition to volunteering since 1998 to conduct a Breeding Bird Survey for the United States Geological Survey and an annual birding tour for the Point Reyes Birding Festival.
