The communication is part of the socialｴs behavior of the bird and other
animals. The analysis of these signals may contribute to the understanding of
biodiversity, for conducting censuses and ecological management of species. The
call of bird of high land in the Central Andes
are scarcely known. In October and December of 2008 we record the song of Phrygilus
fruticeti (Emberizidae) with
the digital recorder (Olympus-VN2000). The sampling method was random walks. The
calls were process whit Syrix bioacousticｴs software. We record the 71 calls, the
variables measured for the description was dominant frequency, total length,
number of phrases of the call. The call is composed for the 5 phrases. The
initial phrase poses two syllables. The mean of total length was 1.47 ｱ 0.34 second and the dominant frequency
was 2905 ｱ 899.7 Hz. This work constitutes a contribution to knowledge of
structure of call and birdｴs communication of land high of Central Andes.
