When I realized that spring was upon us and Golden Gate Audubon’s Birdathon season was fast approaching, a smoke signal was sent to fellow Miwok birders Peter Pyle and Brian Turner seeking consensus on the date for our big day. Okay, I admit that in fact I emailed them, but email would not be allowed on April 20, when for the fifth year in a row, we took the Miwok-style Birdathon challenge.
The rules and the route would be the same: no optics, car, bike, phone, watch, flashlight, etc. Relying on our collective birding experience and the help of a robust spring chorus, we would bird West Marin by foot, and by kayak in Bolinas Lagoon. With this unique challenge we would explore the diversity of habitats present within a small geographical area to ask the question: How many species might the Miwok Indians detect in a single day without using any modern aids?
April 20, while a bit later than past years, was chosen mostly due to tides. A high tide around midday is critical for the kayak component of our count. We realized one result of this choice at dawn, when besides the haunting cries of Spotted Owls we immediately added Swainson’s Thrush to the list, a first. It seems that in past years, we were just a few days too early for this beautiful songster.
From there, the list grew rapidly and predictably; we have started to learn the best spots for site-faithful species that are on territory each year in the same places. Less predictable highlights also delighted the team – a Merlin persistently harassing a Crow (yes, usually the other way around), a skulking Lincoln’s Sparrow at the sewage ponds, White-throated Sparrow near Pine Gulch, flyover Pileated Woodpecker, and even a Rufous Hummingbird.
How well we timed the tide in Bolinas Lagoon is debatable as we spent considerable time walking our kayaks through mud. And while the ducks had largely departed, this part of the day added many water birds to our list.
Perched on the bluffs above Agate Beach, we stared and strained our eyes at Duxbury Reef and beyond. A gray sky all day, it was also dead calm and the lack of wind made for an extraordinarily peaceful moment. Flocks of Brant and Red-throated Loons streamed north, close enough for ID, while others remained just beyond reach without optics. A flock of Black Turnstones below also held Surfbird, a first for us on this count.
In the end we re-entered civilization with 115 species; our high count is 124. Several bad misses were made up by several surprises, and the satisfied Miwoks parted ways, committed to a unique tradition that celebrates nature in the oldest fashion possible.

We’ll be starting to plan for Birdathon 2016 in the fall. Want to share your ideas or get involved? Email Ilana at firstname.lastname@example.org. We’re especially interested in people who might want to lead or take part in a “carbon-free” Birdathon trip – birding without the use of cars or other motorized transport.
