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

birding program while also working as a writer and for the Aspen Institute.
After an international upbringing and work in some of the world’s biggest cities,

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.
