Christmas Bird Count at Los Tarrales, 14 December 2007

Cayaya Birding organized the first Audubon Christmas Bird Count on Atitlan Volcano on 14 December 2007. Two groups were counting birds in Los Tarrales Reserve. One was led by Josué de León Lux on the upper part of the volcano (1400-3500 m), and a second group was led by Claudia Avendaño in the lower part of the reserve (750-1000 m).

A total of 927 birds of 152 species were detected by a total of 9 observers. In addition, 11 species were recorded during the count week. One of the flagship-species of the Atitlan Volcano Christmas Bird Count was the Horned Guan; four birds were seen in the cloud forest on the upper part of the volcano cone. Also Azure-rumped Tanager was recorded in cloud forest. Pink-headed Warbler was seen during the count week.
