Hundreds of songbird species thrive in and depend on Yosemite’s meadows, from black-headed grosbeaks to vibrant western tanagers to spectacled Cassin’s vireos. The birds’ vulnerability to environmental changes makes them key indicators of ecosystem health in Yosemite and beyond.
Since 1990, Yosemite’s songbird-banding program has been collecting data on the park’s resident and migratory avian species, with much of that work funded by Conservancy donors. The songbird studies, among the longest-running in the country, provide vital information about how environmental factors, including drought and decreased snowpack, affect sensitive species.
In 2016, scientists recorded data on more than 2,000 individual songbirds captured in park meadows. In Hodgdon Meadow, where researchers are paying careful attention to how habitat and bird demographics have been affected by the 2013 Rim Fire, the team captured a black-headed grosbeak bearing a tiny GPS “backpack” — the device, which the team had placed on the bird two years earlier, allows scientists to study the journey of this molt-migrant species.
As part of this grant-funded project, visitors and volunteers experienced science in action during a series of hands-on bird-banding demonstrations, while student interns had the incredible opportunity to work with professional ornithologists and receive one-on-one training in conservation techniques.
