Are great-tailed grackles that are on the invasion front and actively expanding the range into new habitat, different in some way from those that are in areas where there have already been many generations of grackles? Did you know great-tailed grackles were originally restricted to Central America, but have rapidly expanded their range north into […]
Always a popular event, Steve Hampton returns to host a Bird ID workshop in advance of our 50th annual Putah Creek Christmas Bird Count (CBC).

The Central Valley has undergone massive habitat change in the past century, creating a heterogeneous landscape. Many researchers lack the ability to undertake long-term biological monitoring on restoration projects and to measure long-term success, particularly on understudied private lands. What’s a researcher to do? To find out, join Yolo Audubon’s virtual January Members Meeting to […]
Kevin Gusé believes that the combination of primates, big game, and birds makes Uganda a truly unique destination. For example, did you know that Uganda is the most bird-diverse country in Africa, with an official list of almost 1,100 species? Please join Kevin as he recounts the adventures of his group during their trip in […]
The Marbled Murrelet (Brachyramphus marmoratus) is a small, cryptic seabird with a range extending from northern California up through Alaska. Like other alcids, murrelets forage in the ocean and exclusively inhabit marine environments when not breeding. Whereas most other alcids nest in large groups near the coast, murrelets typically nest solitarily on the limbs of […]

California has roughly 40 million acres of rangelands that provide food production, carbon sequestration, water infiltration, and habitat for a wide range of species. However, this historic land use is under threat with an average of 20,000 acres a year being lost to development or crop conversion. Climate change, invasive species, aquifer depletion, and outdated […]
Why do some species evolve complex cognitive behaviors while others do not? One hypothesis is that social species need more advanced cognitive abilities than asocial species to deal with the unpredictable behavior of other animate beings. Therefore, sociality may co-evolve with cognitive traits that ease navigating social interactions to increase survival and fitness within a […]
Please join Yolo Audubon’s virtual Members’ Meeting on Nov. 17 when Dr. John Eadie will take us “backstage” to provide a look at his work with the glamourous wood duck. Biologists have studied the charismatic wood duck for well over a century. What more could possibly be learned? As it turns out, quite a bit. […]
