Resumo

The genus Penelope is a group of guans of the family Cracidae, Order Galliformes, which is quite characteristic in Brazil, totaling seven species (Penelope jacquacu, P. jacucaca, P. marail, P. pileata, P. obscura, P. ochrogaster and P. superciliaris). Each guan species has a particular distribution, with the exception of the Rusty-margined Guan (P. superciliaris) that is found in almost all the national territory. The objective of this study involves analyzing the songs of the species of Penelope in different regions of Brazil, and comparing them to those of the generalist species P. superciliaris to know if their singing patterns are modified when overlapping with other species of the genus, thus avoiding competition by acoustic interference. This comparative analysis involving several guan species is the first performed in cracids in the world, thus being highly relevant for future studies. Furthermore, we are providing the diagnostic characteristics, conservation status and ecological data of each species of the genus Penelope reported from Brazil.
