Costa’s Hummingbirds are predominantly desert hummingbirds with striking iridescent purple throat patches that flare out and a purple crown. Their backs are green, and their bellies are white with green coloring on the sides.

Female Costa’s Hummingbirds lack the purple color and are more white on the belly.

Desert scrub, chaparral, and deciduous forest provide the habitat of Costa’s Hummingbirds, and they visit many different species of plants. They also eat small flying insects.

Costa’s Hummingbird Call:


Nests are built quite low at three to seven feet above the ground in shrubs, and they may have up to two broods in a year. Females take about 5 days to build the nest from bark, small leaves, and other material woven together with spiderweb.

They have 1 or 2 broods a year and the eggs take about seventeen days to hatch and the young take another twenty to thirty days to fledge. Females do all the incubating and raising of the young.

Fun Fact:

Costa’s hummingbirds would have to visit nearly 2000 flowers a day to give them the energy they need.
