A total of 33 observers in 8 groups counted birds in Reserva Natural Privada Los Andes, Reserva Natural Privada Los Tarrales, Finca San Jerónimo Miramar, Fincas Santo Tomás Perdido and Santa Teresa, and in the bay of Santiago Atitlán of Lake Atitlán. Weather conditions were favorable, with a clear to partly cloudy sky.
