A beautiful day in our beautiful National Park greeted bird observers David Lawrence, Sue Puder, Art Dorsey, Kat Bradley-Bennett, Mark and Diana Wolenetz, Susan Wade, Tom Dennis and Julie Paranka, Evi Buckner-Opler and Ron Harden. On the way to breeding bird areas, three moose were seen near Sheep Lakes. Next, we visited the trails in Upper Beaver Meadows. After a sack lunch back at the picnic area, some participants ventured up Trail Ridge Road, watching Pika and Yellow-bellied Marmot at Rock Cut, and finally hiking on the Medicine Bow Curve trail. American Pipit and White-crowned Sparrow were seen there, but White-tailed Ptarmigan remained elusive.

February 2026 Field Trip Report - Pella Crossing and Lagerman Reservoir
It was a chilly but sunny start on our February 21 morning field trip with Helmut Retzer, Don Starks, Charlotte Wolleson, new club member Jim Cummings, Anita and David Lawrance at Pella Crossing where we heard a western meadowlark and watched a great blue heron, red-winged blackbirds, ring-necked ducks, Canada geese, a song sparrow, white-crowned sparrows, hooded mergansers, gadwalls, black-capped chickadees, European starlings, mallards, a Eurasian collared dove, and a red-tailed hawk mobbed by a pair of American kestrels.
By late morning, the reservoir itself was otherwise occupied by only a few green-winged teals and several dozen common goldeneyes with the males doing their peculiar head-flipping courtship maneuvers.
As usual, we shared and enjoyed many educational and observational anecdotes, completing the trip with lunch at The Post.
Important Note: During this field trip, we noticed that the west-end portion of the trail at Lagerman Reservoir is closed. This is something that usually doesn’t happen until May for the ground-nesting birds, like Savannah and Vesper Sparrows. The club has been able to verify with Boulder County Open Space that the early trail closure this year is because ground-nesting sparrows are back early and are already defending nesting territory!
