Thank you for flying with us
California is one of the richest hummingbird states on the Hummingbird Trail, with year-round Anna's Hummingbirds, coastal Allen's Hummingbirds, desert-loving Costa's Hummingbirds, and seasonal migrants moving through gardens, canyons, and native plant corridors. From coastal botanic gardens to desert bloom country, California offers nearly every style of hummingbird watching: manicured public gardens, university arboretums, coastal sage scrub, desert washes, and native plant sanctuaries. The best viewing varies by region, but spring bloom from February through May is especially rewarding, while Southern California and the coast can offer hummingbird activity throughout the year.
