Bird Conservancy is finishing up another winter of grassland bird monitoring in Mexico, using radio-telemetry to study survival rates of Baird’s and Grasshopper Sparrows. We follow them to get an inside view into their lives, and sometimes feel a bit like sparrow paparazzi!
Bird Conservancy of the Rockies just completed a second summer season studying breeding season survival in adults and juveniles of nesting Baird’s and Grasshopper Sparrows in the Northern Great Plains of North Dakota and Montana.
Aplomado Falcons once ranged across the northern reaches of the Chihuahuan Desert in Mexico, but their numbers have sharply declined in recent years. Bird Conservancy is working with with local partners and agricultural producers to improve habitat and provide specially-designed nesting platforms, with promising results.
Biologists studying overwinter survival rates of sparrows in the Chihuahuan Desert grasslands of northern Mexico are turning their attention to Loggerhead Shrikes. Taking advantage of shrub encroachment and the favorable habitat it provides for them, shrikes have become an apex predator of birds and many other animals on the landscape.
