This time of year the Arboretum hosts both Anna’s and Allen’s hummingbirds, the two most common species in Northern California. “The density of hummingbirds—the number per area in the Arboretum—is ridiculously high,” says Bruce Lyon, professor of Ecology and Evolutionary Biology at UCSC. “You can watch them feeding on flowers, you can watch their courtship, you can watch them chasing different species. It’s a great opportunity to see some pretty amazing hummingbird biology.”

In celebration of this special time of year, we invite you to visit the garden as much as possible! See our webpage for a schedule of activities and more information about hummingbirds and the abundance of plants at the Arboretum that attract them.

All events are free with paid admission: Adults: $10, Seniors $8 and Youth 4-17 $5. Rain cancels outdoor activities.
