Radio-Telemetry Offers Insights into Mountain Plover Habitat Use

By | Science, Stewardship | No Comments

RMBO is partnering with the University of Colorado-Denver to support a graduate research project to better understand how Mountain Plovers utilize habitat during the nesting cycle. Biologists will study their foraging habits by tracking adult plovers using radio-telemetry. CSU student Jamie Osterbuhr writes about this research, taking place in the crop fields of western Nebraska.

Study: Expansion of Croplands in Chihuahua, Mexico, Threatens Declining Grassland Birds

By | Partners, Science | No Comments

The Chihuahuan Desert grasslands of northern Mexico and the southwestern United States are the principal wintering grounds for 90% of grassland bird species breeding in the western Great Plains of North America. Species such as Baird’s Sparrows, Chestnut-collared Longspurs and Sprague’s Pipits, which rely on this region during the winter, have declined by upwards of 80% since the 1960s. Results from Rocky Mountain Bird Observatory and cooperators’ research, published in February in the journal Biological Conservation, shed light as to why these birds are declining and emphasize that unless immediate action is taken, forecasts are dire.

Sites Added to Grassland Bird Winter Survival Study

By | Science | No Comments

Grassland birds are declining faster than any other group of North American birds. The key to reversing these declines may lie on their wintering grounds in northern Mexico. Writing from Chihuahua, biologist Erin Strasser provides a preview of RMBO’s second season studying the overwintering ecology of Baird’s and Grasshopper Sparrows in the Mexican grasslands.

Saving the Aplomado Falcon in the Grasslands of Chihuahua, Mexico

By | Partners, Science, Stewardship | No Comments

“Another nest has failed.” This is the recurring news that technicians monitoring Aplomado Falcons in Chihuahua, Mexico, have reported over the last 18 years. Private Lands Wildlife Biologists Roberto Rodríguez and Pedro Calderón report from Chihuahua on last season’s monitoring of this iconic, grassland species and efforts to conserve its dwindling habitat there.

Surveying Birds from Mountains to Plains

By | Science | No Comments

Grassland bird populations have declined more steeply than any other group of North American birds. Since 2006, RMBO has partnered with the City of Fort Collins to inventory and monitor grassland birds on city-owned properties near the Colorado-Wyoming border. These properties represent some of the most significant grasslands in northern Colorado and support populations of more than 20 high-priority bird species. Communications Coordinator Teddy Parker-Renga writes about a day in the field surveying birds on these properties and discusses the impact of the Mountains to Plains Region project.
