California dairy families worked with conservation groups to save an estimated 67,000 tricolored blackbirds in the 2015 nesting season. See a short documentary here.

Dairy families have been working collaboratively to protect the Golden State’s endemic tricolored blackbird population. Once numbering in the millions, the tricolored blackbird population has been on the decline in recent decades. While the bird’s population has fluctuated over the years, experts attribute loss of the bird’s natural habitat, such as wetlands and native grasslands, food sources and the state’s crippling drought as causes for the species’ decline.

These developments have resulted in the bird nesting in winter forage fields on dairies, attracted by an inviting combination of cover and food that unfortunately coincides with springtime crop harvest. Exacerbating the situation, tricolored blackbirds tend to cluster in small areas in very great numbers. Tens of thousands of birds – a significant portion of the state’s population – may build their nests on a single farm or even a single field.

To help protect tricolored blackbirds, Audubon California, California Farm Bureau Federation, Dairy Cares, Sustainable Conservation and Western United Dairymen launched a project to find a sustainable solution for managing nesting colonies on farms, with the goal of increasing the statewide population. The group was awarded a $2.1 million Regional Conservation Partnership Program (RCPP) grant through the USDA’s Natural Resources Conservation Service. The project also focuses on habitat restoration and enhancement projects aimed at attracting the birds away from dairy silage fields, instead, encouraging them to nest on existing or to-be-developed wetlands or private lands specifically intended to provide habitat for tricolored blackbirds.

In its first nesting season of working together, an estimated 67,000 tricolored blackbirds were saved through the collaborative efforts of the RCPP group and California dairy farmers. Through funding provided by the California Dairy Research Foundation, these efforts are detailed in a recently released video titled, “Protecting California’s Tricolored Blackbird.” The video is available here.

California dairy families remain committed to protecting the environment and species around their farms, while continuing to produce safe, affordable and nutritious milk for millions of consumers.
