Conteo Navideño de Aves: Volcán Atitlán 2010

La cuarta edición del Conteo Navideño de Aves en Volcán Atitlán se realizó el 15 de diciembre de 2010. Un total de 29 observadores divididos en 10 grupos contaron aves en las reservas naturales privadas Los Andes, Los Tarrales, San Jerónimo Miramar, Santo Tomás Perdido y Santa Teresa, y en las bahías de Santiago y Tolimán en el lago Atitlán. Las condiciones climáticas fueron favorables. Nubes cubrieron el área bajo de 2000 m en la mañana, mientras la noche fue clara y el día soleado en la parte superior del volcán.

Un total de 5393 aves de 237 especies fue registrado. Cinco especies más fueron observadas durante la semana de conteo. Las especies más abundantes durante el Conteo Navideño de Aves con más de 50 individuos registrados fueron (en orden descendiente de abundancia): Fulica americana, Quiscalus mexicanus, Cyanerpes cyaneus, Hirundo rustica, Steligopteryx serripennis, Aratinga canicularis, Colibri thalassinus, Bubulcus ibis, Oreothlypis peregrina, Coragyps atratus, Archilochus colubris, Pheucticus luduvicianus, Notiochelidon pileata, Patagioaenas fasciata, Thraupis abbas, Wilsonia pusilla, Streptoprocne zonaris y Cyanocorax melanocyaneus.

Las aves estrellas del volcán Atitlán-Oreophasis derbianus y Tangara cabanisi-fueron observados también durante este conteo navideño, así como muchas otras especies endémicas de a las tierras altas del norte de Centro América como Penelopina nigra, Campylopterus rufus, Lampornis viridipallens, Atthis ellioti, Aspatha gularis, Troglodytes rufociliatus y Turdus rufitorques.

La observación más notable fue un Aegolius ridgwayi, representando el primer registro de este tecolote poco conocido para el volcán Atitlán. Aythya collaris ocurre irregularmente en el lago de Atitlán. Un grupo de nueve individuos en la bahía de San Lucas Tolimán fue notable. Seis Porzana carolina representan el primer registro para los conteos navideños en el volcán Atitlán.

El Volcán Atitlán es parte del Área Importante para Aves Atitlán (IBA GT015) y este Conteo Navideño de Aves es una herramienta simple para monitorear las poblaciones de aves en esta IBA. Entre las especies prioritarias para la conservación que fueron registradas durante el conteo en 2010 se encuentran dos especies Amenazadas a nivel global (Oreophasis derbianus, Tangara cabanisi) y dos especies Vulnerables (Penelopina nigra, Ergaticus versicolor).

A continuación se presenta una lista de especies y números de individuos registrados durante el cuarto Conteo Navideño de Aves en Volcán Atitlán (nomenclatura según AOU 1998 y suplementos, con la más reciente actualización de AOU 2010).
