behavior

In the Lambayeque region , the birds were observed taking nectar from coral trees and from the psittacanthus plants belonging to the belt flower family , where rust-bellied amazilia ( Amazilia amazilia ) also stayed. In studies of the stomach contents, insects were found to be another food source. The animals tend to move in the lower strata .

distribution and habitat

Distribution area of ​​the bear hummingbird

Bear hummingbirds occur in dry undergrowth and on the edges of forests with deciduous plants in northwestern Peru at heights below 800 meters. In Ecuador they are mostly only found in the extreme southwest of the Loja province . From the canton of El Empalme there have been sightings of specimens at heights of up to 1000 meters.

Etymology and history of research

Eugène Simon described the bear hummingbird in 1901 under the current name Leucippus Baeri . The type specimen came from the Tumbes region and was collected there by Gustave Adolphe Baer (1838–1918), after whom the species was named. The genus Leucippus was discovered in 1850 by Charles Lucien Jules Laurent Bonaparte a . a. for the cinnamon breast hummingbird. The generic name refers to " Leukippos Λεύκιππος " from Greek mythology .
