Christmas Bird Count: Antigua 2011

Compilers: Knut Eisermann & Claudia Avendaño

The third CBC Antigua Guatemala was carried out on 18 December 2011. A total of 26 observers in five groups counted birds in in Finca El Pilar, Finca Filadelfia, at Cerro Alux, and at Agua volcano. Rather strong winds impeded good night birding. At day time the weather improved.
