With spring officially set to begin in a week and hummingbirds beginning their northward migration to Colorado, it’s time to look forward to bright spring flowers and early arriving hummingbirds next month.

This evening’s program will describe information derived from a decade of volunteer field research on Rocky’s hummingbird populations. Topics to be addressed include survivorship and longevity, relative reproductive success, weather effects, genetic studies, and migration corridors. During the course of the survey, Tena and Fred Engelman captured, banded, measured, and released nearly 12,000 hummingbirds of four species as a part of the only avian survey of this scope yet to be conducted in the park. If time permits, they will include a brief presentation on some of Central America’s hummingbirds.
