With summer waning, RMBO has completed its sixth season of conducting surveys under the Integrated Monitoring in Bird Conservation Regions (IMBCR) program. How many birds were counted? What new and rare species were detected? Biologist Nick Van Lanen answers these questions and offers a wrap-up of another successful summer survey season.
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.
Despite sub-freezing temperatures and driving snow, 38 volunteers took part in this year’s Christmas Bird Count at Barr Lake. Count compiler Chuck Hundertmark offers a report on species observed that day, including a few rarities for Barr Lake.
“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.
Now that fall is upon us in the Rockies, RMBO biologists and technicians are finishing proofing data gathered this summer under the Integrated Monitoring in Bird Conservation Regions (IMBCR) program. It’s not glamorous, but with proofing data comes the confirmation of cool new species for the program. Biologist Nick Van Lanen reports on the summer field season and species detected for the first time during IMBCR surveys.
In early June, a LightHawk pilot and his wife volunteered their time and plane to help Rocky Mountain Bird Observatory with a census of Ferruginous Hawks and Golden Eagles nesting in the panhandle region of western Nebraska. How many birds were spotted on their nests? Wildlife Biologist Angela Dwyer offers results from the surveys, used to gauge population stability for these species.
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.
RMBO biologists and field technicians are once again preparing to fan out across mountains, prairies and high deserts to conduct breeding bird surveys under the Integrated Monitoring in Bird Conservation Regions (IMBCR) program. Biologist Nick Van Lanen provides an update on trainings for IMBCR surveys, including a rare bird spotted by a crew member – and former RMBO camper – in South Dakota.
RMBO’s field crew discovered its first Mountain Plover nest of the season on May 8. After the cold start to spring, this newly laid nest with a clutch of three eggs was an important find. Biologist Larry Snyder writes about the find and RMBO’s plover nest conservation program on the RMBO blog.
The pine-oak and cloud forests of West Mexico are critical habitat for endemic and migrant bird species. In March, RMBO wrapped up its first year of surveying birds in the region. Our technicians offer a report from Jalisco, Mexico, on their experiences surveying in this challenging, beautiful terrain, including a list of unique species detected.
