Migrant/Resident: Costa's Hummingbird
Scientific Name: Calypte costae
Conservation Status: Least Concern (Population stable)
The Costa's Hummingbirds migrate and nest in February or March, when desert flowers are most abundant and heat has not yet peaked.
They wander if resources become scarce or temperatures climb too high.
But unlike Rufous and Ruby-throated Hummingbirds, Costa's are short-distance migrants, moving only as far south as northern Mexico in winter.
