Visual and vocal signals are the most commonly used stimuli for communication in birds; however, the role of acoustic non-vocal cues in animal communication is still poorly understood. Here we aim to assess the role of non-vocal sound produced by Scaled doves (Columbina squammata) during take-off. 

Our goal in this study is to examine the social recognition system of the Rufous Hornero (Furnarius rufus), a Neotropical and monomorphic bird species that sings duets. We will specifically evaluate whether reproductive phenology, population density, and distance between territories are related to the "dear enemy" and "nasty neighbors" effects.

Social behavior has been found to influence decision-making in various ways such as foraging, evading predation, and aggression. In larger groups, individual investment in vigilance can decrease due to collective benefits, like the dilution effect and the many-eyes effect. The goal of this study is to analyze the impact of group size on vigilance behavior and the role of "wing raised-upward" by Ruddy Ground-doves (Columbina talpacoti) during social behaviors.
