El sexto Conteo Navideño de Aves en Volcán Atitlán se realizó el 15 de diciembre de 2012. Un total de 23 observadores divididos en 8 grupos contaron aves en Reserva Natural Privada Los Andes, Reserva Natural Privada Los Tarrales, Finca San Jerónimo Miramar, y en la bahía de Santiago en el lago Atitlán. Las condiciones climáticas fueron favorables con poco viento y pocas nubes.
Un total de 5031 aves de 228 especies fue registrado. Tres 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, Cyanerpes cyaneus, Oreothlypis peregrina, Coragyps atratus, Aratinga canicularis, Stelgidopteryx serripennis, Colibri thalassinus y Icterus galbula.
La mayoría de las especies endémicas de las tierras altas del norte de Centro América fue registrada, incluyendo Tangara cabanisi, Cardellina versicolor, Oreophasis derbianus, Penelopina nigra, Campylopterus rufus, Lampornis viridipallens, Atthis ellioti, Aspatha gularis, Troglodytes rufociliatus, Cyanolyca pumilo y Turdus rufitorques.
Notable fueron 22 Anas americana en el lago de Atitlán. Este pato es un visitante no reproductivo poco común en Guatemala. 28 Ardea herodias marcaron el conteo más alto de esta especie durante todos los conteos navideños en 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 2012 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 sexto Conteo Navideño de Aves en Volcán Atitlán (nomenclatura según AOU 1998 y suplementos, con la más reciente actualización de AOU 2012).
