Connecting People with Birds
Our mission is to share the fun of birding, promote conservation and scientific understanding of wild birds and their habitats, and offer engaging, science-based education emphasizing the communities of Napa and Solano counties.

Get Involved
Napa-Solano Birds is predominantly a volunteer organization. To make our programs successful we need membership involvement in all of our activities. Donating even a few hours of time can help a lot. There are all sorts of fun ways to get involved – from helping out with a classroom visit, bird walk or special event, to monitoring your own area for breeding birds.

Bird of the Week – Black-throated Gray Warbler
NSAS Monthly Speaker Series Presents: Birds of the California Delta with Aaron Haiman
April 9, 2026 at 7:00 p.m. at the Benicia Public Library
About the Program: Based on the new book, Birds of the California Delta, this talk will focus on the Sacramento-San Joaquin Delta as a place of connections and complexities. This is a place where rivers meet one another, where freshwater meets salt water, where fish link inland forests with the open ocean, where birds from the north come for the winter, and where birds from the south come to breed. The Delta is also a place of complexity. How water interacts with land and forms soil is a complex process. How humans use water, and land contains a nest of complex pressures. All these connections and complexities play out on a daily basis throughout the Delta.
About the Presenter: Aaron N.K. Haiman, a life-long birder, began volunteering at a young age with bird research organizations before receiving a BS in Environmental Science from UC Berkeley as well as MS degrees in Avian Science and Animal Behavior from UC Davis. Aaron guides bird walks, mentors high school students in ecology and sustainability, leads a youth bird-a-thon team, gives presentations on birds and habitat restoration, and is active on YouTube and social media under the handle “A Birding Naturalist” sharing knowledge of birds, nature. and science. He works for the State of California and lives in West Sacramento.
We meet in person at the Benicia Public Library at 7:00 p.m. and via Zoom:

NSAS will be Participating in the CA Breeding Bird Atlas Project
We are searching for Volunteers to help us cover our Survey Areas in both Napa & Solano Counties. If you would like to volunteer, please contact Mark Stephenson at . What is a Breeding Bird Atlas (BBA)? And why is it so important? A Breeding Bird Atlas (BBA) is a large-scale, multi-year project that documents the breeding distribution and activity of bird species within a specific geographic area, such as a state or county. It provides crucial data for understanding changes in bird populations and their habitats, informing conservation and management efforts. This current State-wide project, being coordinated by the California Bird Atlas organization, with well- known birder, Van Pierszalowski serving as the Executive Director, is especially important, as California is one of only 6 states that has never engaged in a state-wide atlas. In fact, only 16 of our 58 counties have ever published a BBA. We are proud of the work by our many volunteers who completed 2 of the 16 state-wide atlases in both Napa and Solano Counties in years past. However, it has been 32 years since NSAS completed the field work for the first Napa Breeding Bird Atlas in 1993. The information was published 10 years later in 2003. The field work for the first Solano County BBA was held from 2005-2010 more than 15 years ago and was published in 2014. Many changes have occurred in our area during the past 15–30 year span as a result of housing and urban development that are sure to have impacted birds and their habitats since our last BBAs were completed. A new BBA would be of huge value to document the changes to birds, our landscape, and consequential conservation needs and priorities.
See our Spring Newsletter for more details on using eBird to post Breeding Bird observations!
In order to support this endeavor, we are attempting to raise $10,000 to contribute to the success of this project. We are hoping that our members will value this project as much as our Board of Directors and support us during the coming months both as volunteer birders, and in or efforts to raise these funds. We would like to thank our members in advance for their incredible support over the years. We are hopeful this BBA Project will continue our important work of supporting birds and protecting critical habitats throughout our region and across our state.

NSAS Monthly Field Trip to Mount Diablo’s Mitchell Canyon:
Thursday, April 23rd from 8:00 a.m.- 3:00 p.m. with Mark Stephenson & Phil Burton
This is the perfect time of year to view Mt. Diablo’s migrants and resident birds. Deer Flat Creek is flowing from Spring showers and the canyon is resounding with bird song. Resident Anna’s and migrating Calliope Hummingbirds are feeding on spring flowers and males can be heard zipping down from hundreds of feet up in their display flights hoping to impress a mate. Acorn, Nuttall’s & Downy Woodpeckers are actively chiseling out nests. Olive-sided, Western and Ash-throated Flycatchers are setting up territories and Hammond’s are passing though on their way to the Sierras. Hutton’s and Warbling Vireos will also be actively starting nest building. Warblers including our resident Orange-crowned and Wilson’s will be singing along riparian corridors and Yellow-rumped, Nashville, Black-throated Gray along with an occasional Hermit will be feeding in the trees tops. In the higher chaparral we expect to find CA Thrashers, Rufous-crowned and Bell’s Sparrows.
Look for eBlasts with more details about this exciting Field Trip! Registration Sign-up Information will be sent out on Saturday, April 11th at 9:00 a.m.
