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!
This photo journal highlights the most recent winter field season monitoring grassland birds in the Chihuahuan Desert in Mexico. Teaching telemetry, radio tracking Grasshopper Sparrows and assessing predation/mortality rates are all a major part of this program.
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.
