Escudo hummingbird
The Escudo hummingbird is a hummingbird in the subfamily Trochilinae. It was long considered a doubtfully distinct species, but more recently it is generally treated as a subspecies of the rufous-tailed hummingbird, A. tzacatl.
It is endemic to Isla Escudo de Veraguas in Panama. Except for its larger size, it is similar to the rufous-tailed hummingbird. Its natural habitat is tropical moist shrubland and woodland. With a total range estimated at only 3 km², it is potentially threatened by habitat loss or invasive species.
When it was still considered a good species, it was classified as Vulnerable species by the IUCN, noting that any evidence of a declining population could lead to an uplisting to Critically Endangered status. In 2008, it was removed from the IUCN Red List however, as only species are included therein.Footnotes
