Costa’s

Common name: Costa's Hummingbird
Scientific name: Calypte costae
Clades: Mellisugini - Bees

A Costa’s hummingbird mature adult growing to only 3–3.5 in (7.6–8.9 cm) in length, a wingspan of 11 cm, and an average weight of 3.05 g for males and 3.22 g for females.

Costa's Hummingbird is a fascinating and striking species found in the arid brushy deserts and gardens of the Southwestern United States and the Baja California Peninsula of Mexico. This compact and short-tailed bird boasts a slightly drooping bill that sets it apart from other similar hummingbirds such as Anna's and Black-chinned.

The male Costa's Hummingbird is a sight to behold, with a brilliant purple crown and throat that extends down to a point on each side. However, in dim lighting, these vibrant colors may appear black. The females, on the other hand, exhibit a plainer appearance with a greenish back and dingy grayish underparts. An identifying feature of both genders is the pale eyebrow that wraps around the dark cheek, along with the bird's droopy bill and dumpy, short-tailed shape.

One notable behavior of this hummingbird species is its tendency to wander from the desert after breeding, expanding its habitat to include various environments, even venturing into backyards with sugar water feeders. This adaptability allows bird enthusiasts in the region to enjoy the presence of these remarkable creatures up close.

In addition to its remarkable physical features and behavior, the Costa's Hummingbird is also noted for its very high-pitched song, adding to the allure of encountering this bird in the wild.
