Conteo Navideño de Aves: Tikal 2009

La cuarta edición del Conteo Navideños de Aves en Tikal se realizó el 21 de diciembre, 2009. Un total de 36 observadores divididos en ocho grupos contaron aves en el parque nacional. El clima no fue favorable, estuvo lloviendo por la noche y parte de la mañana.

Un total de 2256 individuos de 172 especies fueron registrados. Además otras 14 especies fueron observadas durante la semana de conteo. Las especies más abundantes con al menos 40 invididuos detectados fueron Psarocolius montezuma con 400 individuos en un dormidero, seguida por Dendroica magnolia, Platyrinchus cancrominus, Hylocycla mustelina, Cyanocorax morio, Habia rubica, Ramphastus sulfulratus y Meleagris ocellata. Las aves migratorias Neártico-Neotropicales más abundantes fueron Dendroica magnolia, Hylocichla mustelina, Polioptila caerulea, Setophaga ruticilla, Wilsonia citrina, Dumetella carolinensis y Oporornis formosus.

Una observación notable fue un Águila Crestada (Morphnus guianensis) que fue vista en la sección oeste del Parque Nacional Tikal. Esta especie no es registrada a menudo en Tikal debido a su comportamiento escondidizo. Un sólo Ciccaba virgata fue el único tecolote registrado durante el conteo (debido a la lluvia). Los tecolotes Ciccaba nigrolineata y Megascops guatemalae fueron observados durante la semana de conteo.

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.

A continuación se presenta una lista de especies y cantidades de individuos registrados durante el cuarto Conteo Navideño de Aves en Tikal (nomenclatura según AOU 1998 y suplementos, con la actualización más reciente de AOU 2009).
