Morning Birding at Hallam Lake

Discover the diverse birdlife of the Roaring Fork Valley with ACES on select Tuesday mornings throughout the year. Birders of all experience levels are welcome! Outings meet at ACES’ Hallam Lake Nature Preserve or Rock Bottom Ranch (see dates for corresponding locations), and begin with a brief orientation, followed by birding in the field. We explore bird activity in a variety of local habitats at these ACES sites and adjacent birding hot spots. Every outing offers rich opportunities to learn about bird behavior, identification, migration, and local habitats, as well as field craft skills to enhance your birding experience. Bring your binoculars or borrow a pair provided by ACES.

Join us and the birds on these beautiful and serene early mornings!

Rebecca illuminates the natural world and gives participants tools and inspiration to
keep the joy of learning alive. Her knowledge of birds and their habitats is
complemented by a foundation in ecology and regional history, giving her the big-picture
context she loves to share. Participants appreciate her welcoming style, infectious
enthusiasm, and her ability to make complex scientific concepts both accessible and
fascinating. First arriving at ACES as a Summer Intern in 1993, Rebecca has held

Rebecca can be found happily distracted by birds while gardening, playing classical
piano, and pursuing all kinds of mountain adventures with her family and friends.
