Bring a sack lunch if you want to join us for lunch under the canopy after the hike. Bathrooms available near the ranger station and at the bottom of the canyon.

The trip is approximately a 3 mile long round trip with steep trails and some slippery, rocky soil in areas. You may want to bring hiking poles. Be aware this is an active motorcycle trail that we will be walking on.

Rainforest in Flight: Birds of the Ecuadorian Amazon
2026-04-14 07:30 - 21:00 (America/Los_Angeles) | Central United Methodist Church, 3700 Pacific Avenue, Stockton, California
Presenter: Jim Gain

In the late fall of 2025, I joined five other adventurers for a descent into the Amazon Basin. This Zoom Program centers on our time at the Sani Bird Lodge. Nestled deep within the Ecuadorian Amazon near the broad, meandering Napo River, Sani Bird Lodge sits at the heart of one of the most biodiverse regions on Earth, surrounded by pristine rainforest that forms a living bridge between Yasuní National Park to the south and the Cuyabeno Wildlife Reserve to the north. Together, these protected areas create a vast ecological corridor—an unbroken sweep of forest where life thrives in staggering abundance. The lodge’s grounds are alive with over 550 bird species.

Jim Gain is a biologist by training, an educator for more than 35 years, and a lifelong naturalist whose curiosity has fueled decades of work in citizen science and conservation. His involvement with the Stanislaus Audubon Society spans over three decades in nearly every leadership role, including past president, complemented by service on the Central Valley Bird Club board and years with the Modesto Camera Club. He remains deeply engaged in the birding community as a Webmaster, eBird Reviewer, and member of the Stanislaus County and San Joaquin County Bird Records Committee. Blending photography with field observation has become one of his greatest joys, and his images have been featured on platforms such as Audubon Field Guide, Birds of the World, All About Birds, and the Merlin Bird ID App—reflecting a lifelong commitment to celebrating and sharing the beauty of the natural world.

We intend to bird several locations around Mono Lake.

Birds we’ll be looking for include Greater Sage Grouse, Common Nighthawk, Common Poorwill, Costa’s and Calliope Hummingbird, Williamson’s Sapsucker, Lewis’s Woodpecker, various flycatchers, Plumbeous Vireo, Pinyon Jay, Woodhouse’s Scrub-Jay, Black-billed Magpie, Juniper Titmouse, American Dipper, Mountain Bluebird, Gray-crowned Rosy Finch, Cassin’s Finch, Red Crossbill, Pine Siskin, Black-throated, Sagebrush and Vesper Sparrow, Yellow-breasted Chat and Virginia’s Warbler. And there’s always the possibility of something rare showing up.

Plus, John will lay out some traps to see what kind of small mammals we can catch (they will be released unharmed after we make our observations). John began his interest in Mono Lake while working as an undergraduate assistant in a study of chipmunks in 1975. He went on to study kangaroo mice on Mono Lake’s dunes while a graduate student at U.C. Davis and has studied small mammals in the Sierra Nevada, San Joaquin antelope squirrels and Mojave ground squirrels. John retired from teaching biology at Mills College in 1983 and currently lives near Oakdale, CA.

This will be a 2-3 day trip. We plan to arrive late Friday (if we arrive before dark we may do a little evening birding) and then meet participants at Whoa Nellie Deli, 22 Vista Point Dr, Lee Vining, CA 93541, early Saturday morning, but anyone is welcome to join us later. We will bird all day Saturday and a big chunk of Sunday before heading home, but, of course, anyone is free to head back at any time. More details will be announced as the date approaches.
