Conteo Navideño de Aves: Tikal 2010

Treinta y tres observadores en ocho grupos participaron en el quinto Conteo Navideños de Aves en el Parque Nacional Tikal el 21 de diciembre de 2010. El clima fue favorable, nublado en parte y sin lluvia y viento.

Un total de 1807 individuos de 172 especies fueron registrados. Además otras cinco especies fueron observadas durante la semana de conteo. Las especies más abundantes con al menos 25 individuos detectados fueron (en orden descendiente de abundancia): Psarocolius montezuma, Dendroica magnolia, Psilorhinus morio, Hylocichla mustelina, Hylophilus decurtatus, Oporornis formosus, Schiffornis turdina, Amazona farinosa, Thryothorus maculipectus, Habia fuscicauda, Platyrinchus cancrominus, Meleagris ocellata, Caryothraustes poliogaster, Dumetella carolinensis, Mniotilta varia, Oncostoma cinereigulare y Lanio aurantius.

Notable fue un Limnothlypis swainsonii y un Melanoptila glabrirostris, las cuales son raras en Tikal. Falco deiroleucus-una de las aves banderas de Tikal-fue observado alimentándose de murciélagos (Artibeus cf. literatus) (ver video).

El Parque Nacional Tikal es parte del Área Importante para Aves Maya-Lacandón (IBA GT001) y este Conteo Navideño de Aves apoya el monitoreo de las poblaciones de aves en esta IBA.
