The grasslands of the Chihuahuan desert provide important overwintering habitat for over 90% of the migratory grassland species in western North America. Recently, our team joined partners and private landowners on a scenic tour through northern Mexico to visit some of Sustainable Grazing Network ranches that are working to conserve and restore grassland habitat for the benefit of people and birds.
After several decades of steep declines, Aplomado Falcon populations are slowly rising again in the Chihuahuan Desert in Mexico, thanks to the efforts of our local partners, ranchers and biologists who are working hard to improve habitat, providing nesting locations, and closely monitor the progress of this threatened species.
Mixed-grass prairie in the Northern Great Plains represents critical habitat for wildlife of all kinds, including our specialty at Bird Conservancy of the Rockies – birds! Read on to learn more about our full life cycle monitoring on the breeding grounds and how technology is playing a role in helping us conserve birds and their habitats.
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.
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.
Rocky Mountain Bird Observatory biologists are back in Colorado after a fruitful winter studying grassland birds on their wintering grounds in northern Mexico. Before digging too deep into the data, biologist Erin Strasser offers a preliminary look at what they learned during season three of this study.
Rocky Mountain Bird Observatory’s third season of studying survival and habitat use of Baird’s and Grasshopper Sparrows is under way on their wintering grounds in the grasslands of northern Mexico. Writing from Chihuahua, biologist Erin Strasser shares an update on capturing and tracking sparrows, insights gained so far this season and captivating photos from the field.
Spring migration is under way. Just as the birds return north, so do the RMBO scientists who study them on their wintering grounds. Back home in Colorado, biologist Erin Strasser offers preliminary results from a second season studying winter survival and habitat use of Baird’s and Grasshopper Sparrows in the Chihuahuan Desert grasslands.
