Rocky Mountain Bird Observatory’s International Team is monitoring and banding birds in the Chihuahuan Desert grasslands in northern Mexico with the help of 26 local field techs the team trained in early January.
As shown in the photo, field crews remove birds that are harmlessly captured in mist nets to gather data to guide conservation efforts. After receiving a USGS-issued leg band, the birds are weighed, measured and inspected before being released.
Birds including Baird’s Sparrow (pictured below), Grasshopper Sparrow, Chestnut-collared Longspur and many others winter in Mexican grasslands before returning to the Great Plains in spring. RMBO is working to conserve their disappearing winter habitat and boost their winter survival.
