Adults of both sexes show an iridescent green back, white eye ring and a rounded black tail projecting beyond their wing tips, from which their name was inspired.

The broad tailed hummingbird is found from Guatemala to Mexico, and western United States and Western Canada during summer, while wintering regions are mainly in southern Mexico and Guatemala. Some populations of the broad tailed hummingbird in southern Mexico and Guatemala do not migrate, a variation in behavior called "sedentary". These types of flower are characterized by high nectar production and red corollas with a tubular shape, such as Aquilegia elegantula.

This species conservation status is “Least Concern ”, indicating it is not an endangered species, having a wide range and moderate population size, although one survey indicated a 52% decline in population between 1966 and 2015. It appears to be adapted to human modified habitats.
