Song complexity includes different measurements, such as repertoire size, song rate, and frequency bandwidth
Ecological and sexual selection pressures are known to influence these metrics, but relatively few studies have investigated the relationship between song complexity and the environment across broad geographical scales |
The blue-black grassquit (Volatinia jacarina) is a small bird that occurs from Mexico to Argentina, and is commonly observed in grasslands and urban areas
Here, our objective is to understand the relationship between song complexity, latitude, seasonality, and species richness using the blue-black grassquit as a model species |
