El Conteo Navideño de Aves No. 11 en el Volcán Atitlán se llevó a cabo el 20 de diciembre de 2017. Un total de 26 observadores organizados en 10 grupos contaron las aves en Reserva Natural Privada Los Tarrales, Finca San Jerónimo Miramar y Reserva Natural Privada Los Andes, así como en el bosque municipal de Santiago Atitlán cerca del Mirador Rey Tepepul, en el Volcán Atitlán, en el Volcán Tolimán y en la bahía de Santiago Atitlán del Lago de Atitlán. Las condiciones climáticas fueron favorables, con cielo claro a nublado, sin lluvia.
Un total de 4423 aves de 274 especies fue registrado, tres especies más fueron observadas durante la semana del conteo. Las especies más abundantes durante este Conteo Navideño de Aves con más de 50 individuos detectados fueron (en orden descendente de abundancia): Streptoprocne zonaris, Chaetura vauxi, Psittacara strenuus, Coragyps atratus, Oreothlypis peregrina, Patagioaenas fasciata, Quiscalus mexicanus, Colibri thalassinus, Setophaga townsendi, Steligopteryx serripennis, Cyanerpes cyaneus, Tangara cabanisi, Myadestes occidentalis, Eupsittula canicularis, Cyanocorax melanocyaneus y Turdus grayi.

Muchas de las especies endémicas de las tierras altas del norte de Centro América fueron registradas durante el conteo, incluyendo Oreophasis derbianus, Penelopina nigra, Strix fulvescens, Glaucidium gnoma cobanense, Tangara cabanisi, Aspatha gularis, Campylopterus rufus, Lampornis viridipallens, Troglodytes rufociliatus, Atticora pileata, Cyanolyca pumilo, Turdus rufociliatus y Spinus atriceps.

Entre las especies prioritarias para la conservación que fueron registradas durante el conteo en 2017 se encuentran Oreophasis derbianus y Tangara cabanisi, Amenazadas a nivel global, y dos especies Vulnerables (Penelopina nigra y Cardellina versicolor).
