When spring arrives and the snow begins to melt, bears start to wake up after months of hibernation. It is an exciting time of the year for bears and park visitors. When bears emerge from their dens, understandably hungry, they immediately begin to search for food. Never feed a bear, and be sure to store food and clean up thoroughly after meals. Learn more about bears in parks and follow these tips to stay safe.

Hummingbirds in Cabrillo National Monument, California

Most species (about 300!) of hummingbirds live in Central and South America, but about 26 species visit the U.S. during Spring. Their northern migration depends on the flowering times of native plants, so climate change can affect this synchronization. One species in particular, Anna’s hummingbird, calls Cabrillo National Monument home year-round. Another species, the Calliope hummingbird, typically makes its appearance in April. This species in the smallest bird in the U.S.
