(Note: The above photo from early 2022 may still be an option you may wish me to employ this spring/summer in 2023 for your birding tour? If so, please let me know. I’m flexible, as your health is paramount in response to the Covid-19 virus syndrome. To learn more about how I am able to accommodate your Covid concerns, please feel to contact me by clicking here.)

Hooded WarblerAt WarblerWatch.com, you can click on my resume to read about my environmental consulting experience as a long-time Certified Wildlife Biologist Asc. and learn that my clients include landowners, environmental consulting firms, tree companies* (* = I am a recommended Consulting Avian Biologist at Tree Care For Birds), engineering firms, planning departments, sanitary districts, cannabis growers, vineyard owners, law firms (as an expert witness), and neighborhood groups — all of which hire me as a freelance consultant to assist with a) field surveys; b) pre-construction surveys; c) habitat restoration (including flood control restoration management plans) to address erosion problems in watercourse, creeks, rivers, and riparian areas after heavy rain events d) tree removal surveys (to ensure bird protection for nesting birds); and e) regulatory/permitting services related to local, state, and federal regulatory measures. 

Post survey, my followup regulatory compliance reports {e.g., biological assessment reports, initial study reports, “biological resources” chapters for Environmental Impact Reports (EIR)} are submitted to owners, stakeholders, local planning departments, and state and federal government agencies (e.g., US Fish & Wildlife Service, California Department of Fish & Wildlife, US Army Corps of Engineers, Regional Water Quality Control Board, among others).                                                                            

For example, a typical bird survey I conduct occurs to ensure a client complies with applicable local, state, and federal measures related to the protection of nesting rare and common bird species, such as Ridgway’s Rail (for which I possess a federal survey permit, along with my other federal survey permits for California Tiger Salamander and California Red-legged Frog).

My birding tours and Birding Guide role for the last 25 years include San Francisco Bay Area birding tours, California bird watching tours, and San Francisco birding tours as a California birding guide, San Francisco birding guide, Marin County birding guide, and Sonoma County birding guide.

Click here to read details about my Birding Tours, including cost options that fit your preference, in addition to how I assist “life listers” attain their goals (such as the 20 new “life” bird species I helped a birder in 2021 add to her previous 8,100 “life list” total).

Thus: perhaps you’d like to visit the best, Prime Time birding hotspots? If so, here are two of the finest options in the San Francisco Bay Area: 1) Sonoma County, where I regularly lead Sonoma County birding tours to see Bodega Bay birdsand 2) Point Reyes National Seashore where more than 490 bird species have been detected, including dozens of vagrant species at Prime Time birding hotspots that I’d be pleased to share with you on a birding outing.

My WarblerWatch web site also features a link to my blog in relation to college-level birding classes I have periodically taught since 2003 as an Adjunct Faculty member at Merritt College (Oakland, CA), including recent Fundamentals of Ornithology and  Bird Song Ecology & Identifying Birds by Ear* college classes. (* = This class theme continues to be one of my most “in-demand” offerings among several other diverse classes that I teach  (e.g.,  Raptors of the San Francisco Bay Area and Waterbirds of the San Francisco Bay Area, among others — as well as private and group tours for individuals or tour companies that hire me, such as Road Scholar).

For more details available; please feel free to write me at DanielEdelstein@att.net

In addition, please click on my web site’s Birding Links section where a “pull down” menu hosts several informative birding articles, as well as my “Nature Watch Phenology Calendar.” It features recurring land and sky events corresponding by month to natural phenomena specific to central and northern California. There’s also a 200 bird song species’ Bird Song Memory Phrases (or Bird Song Mnemonic) list at the Birding Links section to enjoy, if you’re wondering how to identify bird songs by ear and identify bird calls by ear. 

Click here if you wish to see an archived recording of my recent 2021 “Zoom” presentation titled “Discovering Wood-warblers of Marin County,” that was the highest ever viewed Speaker Series program hosted by the Marin Audubon Society (96 people watched). 

Below, a photo of me is at the 2019 American Ornithological Society annual conference where I delivered two field research presentations, one of which highlighted the successful results of my Canada Goose management actions since 2010 at a site where my ongoing consultancy actions have included addling eggs and authoring an Integrated Goose Management Plan to successfully reduce an overpopulation of this invasive species.

Lastly: Increasing Consulting Biologist roles I perform include a) assisting clients that hire me due to flooding events in N. California that require my experience in creating habitat and plant restoration plans for watercourses, streambeds, and riparian areas impacted by high water flood events and storm damage. In turn, my restoration plans allow clients to obtain permits from local planning departments to rehabilitate their damaged habitats. b) helping landowners benefit financially from a new California SB9 state law that allows them to divide their parcel into two or more legal parcels after I conduct a survey and submit a followup compliance report.

{* = I possess a federal 10(a)(1)(A) permit that is valid through March 25, 2024 to conduct field surveys for the following state of California and federal rare, listed species: Ridgway’s Rail (formerly California Clapper Rail), California Tiger Salamander, and California Red-legged Frog.}
