Colibrí de Isla Escudo de Veraguas--Es una especie endémica (exclusiva) de esta pequeña isla, ubicada aguas afuera de la costa de Veraguas y la Comarca Gnobe Bugle. Muchas otras islas de Panamá contienen especies y sub-especies y hábitat muy valiosos y únicos para conservar la biodiversidad de nuestro país. Los panameños debemos ser celosos de los planes y propósitos que afectan nuestras islas y costas. De acuerdo a criterios de conservación esta especie es Vulnerable a la extinción. --------------------------------------------------------------------------------------------------------------- 2005 IUCN Red List Category (as evaluated by BirdLife International - the official Red List Authority for birds for IUCN): Vulnerable Justification This poorly known species is Vulnerable because it has a very small range. No specific threats are currently known, but any evidence that the population is tiny, or of a decline, would result in a reclassification as Critically Endangered.
