Heliangelus regalis Fitzpatrick, Willard s Farm in the Ecuadorian Andes, 59 km northwest of its previously known range. The hummingbird was observed actively feeding on Satyria leucostoma (a species of Ericaceae) in a patch of scrubland within a cattle pasture for 58 days and displayed nonaggressive behavior towards other birds. This find provides new information on ecological flexibility of H. regalis in a humanmodified landscape and provides novel insights into the behavior and natural history of this species.
Proaño et al. (Tue,) studied this question.
