Date: 1/14/26 8:56 am From: 'BCO gal' via Colorado Birds <cobirds...> Subject: [cobirds] Next Thurs., 1/22 - CFO Speaker Series: Floral Resources for Migratory Hummingbirds in the CO Rocky Mtns
The Rocky Mountain Biological Laboratory (RMBL) is home to many migratory
scientists, and one resident breeding hummingbird species (Broad-tailed)
and two species of post-breeding migrants (Rufous and Calliope). While
there, the birds feed on a variety of wildflowers, but the timing of both
migration and flowering of food plants is changing as a result of climate
change.
A 52-year study of the timing and abundance of flowering by many of the
species visited by hummingbirds has documented the ongoing changes, and
those data provide some insights into the challenges faced by migratory
birds. David Inouye, recently retired professor and current researcher at
the RMBL (where he started work in 1971) will talk about his long-term
studies of the hummingbirds and the wildflowers at RMBL.
Join us for this informative presentation which is part of Colorado Field
Ornithologists' Speaker Series aka Dead of Winter Knowledge Quest.
