Return of the Aplomado Falcon?

By | International Programs, Land Stewardship, Monitoring Programs, Science | No Comments

The Chihuahuan Desert population of Northern Aplomado Falcon shrunk dramatically a century ago and was lost from the southwestern U.S. A tiny population survived in Mexico, but its continued survival is tenuous due to habitat loss and other factors. A tri-national partnership is monitoring this population’s breeding success and conducting a demographic study that includes satellite telemetry of juvenile falcons. What we are learning is guiding conservation and helping gain support from private landowners on the ground. The recent appearance of a young male falcon in New Mexico fosters hope that the Northern Aplomado Falcon might even be able to someday recolonize the Southwestern U.S.

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.

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.

“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.
