Compilado por Knut Eisermann y Claudia Avendaño, CAYAYA BIRDING, Enero 2012
El quinto Conteo Navideño de Aves en Volcán Atitlán se realizó el 20 de diciembre de 2011. Un total de 30 observadores divididos en 8 grupos contaron aves en Reserva Natural Privada Los Andes, Reserva Natural Privada Los Tarrales, Finca San Jerónimo Miramar, Fincas Santo Tomás Perdido y Santa Teresa, y en las bahía de Santiago 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 5344 aves de 239 especies fue registrado. Cuatro 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 descendente de abundancia): Fulica americana, Quiscalus mexicanus, Cyanerpes cyaneus, Hylocharis eliciae, Oreothlypis peregrina, Archilochus colubris, Coragyps atratus, Stelgidopteryx serripennis, Thraupis abbas, Colibri thalassinus, Aratinga canicularis, Bubulcus ibis, Setophaga townsendi, Bolborhynchus lineola y Cardellina pusilla.
Oreophasis derbianus fue observado durante la semana del conteo. La mayoría de las especies endémicas de las tierras altas del norte de Centro América fue registrada, incluyendo Tangara cabanisi, Cardellina versicolor, Penelopina nigra, Campylopterus rufus, Lampornis viridipallens, Atthis ellioti, Aspatha gularis, Troglodytes rufociliatus, Cyanolyca pumilo, Icterus maculialatus y Turdus rufitorques.
Notable fue un registro de Contopus cooperi, el cual es raro durante el invierno, y dos Aythya americana en el lago de 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 2011 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 quinto Conteo Navideño de Aves en Volcán Atitlán (nomenclatura según AOU 1998 y suplementos, con la más reciente actualización de AOU 2011).
