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.
Eastern Screech-Owls are the most common owl species in North America, yet little is known about their habitat needs or population dynamics. To fill these knowledge gaps – and get citizens involved in science linked to their natural environment – RMBO launched a new project last month in Fort Collins, Colorado, to monitor Eastern Screech-Owls along the Cache la Poudre River.
Mid-April has arrived, and every year at this time our minds turn to the same thing. No, not taxes. Hummingbirds! Scott Menough, owner of Wild Birds Unlimited of Denver, offers tips on attracting these spectacular hovering jewels of nature to your backyard.
There are few sights in life more majestic than a Bald Eagle soaring across a clear blue sky. Fortunately, this is a far more common occurrence today than it was 40 years ago. Educator Emily Snode writes about RMBO’s Bald Eagle Watch and its impact on Bald Eagle populations along the Front Range.
Rocky Mountain Bird Observatory had a productive and successful first field season studying Baird’s and Grasshopper Sparrow overwintering survival and habitat use in the Chihuahuan Desert grasslands of northern Mexico. From early November to early March, RMBO gathered a massive amount of novel and informative data on these two species at Reserva Ecológica El Uno near Janos, Chihuahua, Mexico.
Every spring, more than a half-million Sandhill Cranes migrate through central Nebraska, where they stopover and spend a few weeks feeding in and along the North Platte River and surrounding land. Since 1971, the Rivers and Wildlife Celebration has been an annual event timed with this great bird migration.
It’s cold as I work my way up the dark west side of Dinosaur Ridge. The fresh snow crunches then slips under my feet as I clamber with my binoculars and scope to the observation view point. Outreach biologist Jeff Birek writes about a typical – and always eventful – day monitoring birds as part of RMBO’s HawkWatch citizen science program.
Before conducting field surveys, RMBO staff contact landowners for permission to access their land. Through these series of phone conversations and e-mail exchanges, a similar question from landowners often arises, “Why do you want to survey that particular location, especially when there are better birding spots nearby?”
On a recent cold and snowy Friday, students from St. Agnes Catholic School in Scottsbluff spent an afternoon on an indoor camping trip. Educator Maggie Vinson writes about the wintry day where the outdoors were brought inside for students.
A herd of bison grazes the golden-hued grasslands, Ferruginous Hawks patrol the skies for jackrabbits, and packs of coyotes yip back and forth across the prairie dog colonies. Thus was our welcoming as we arrived at Reserva Ecológica El Uno near Janos, Chihuahua, Mexico on the afternoon of Nov. 11. Our mission: Catch and place radio transmitters on Baird’s and Grasshopper Sparrows this winter to track them and study their habitat use and overwinter survival.
