Jaguar (Panthera onca) in Argentina. The jaguar is the third largest feline species and the largest in the Americas.

In collaboration with researchers in Argentina and Italy, Roberto Refinetti studied the timing of behavior of the domestic cat and eight of the ten species of South American wild cats. The results were published in the journal of Physiology and Behavior in an article titled “Daily rhythmicity of behavior of nine species of South American feral felids in captivity.”

Researchers found that all species exhibited daily rhythmicity of behavior, but there was not a sharp division between diurnal (day-active) and nocturnal (night-active) felines. Instead, what was found was a gradient of diurnality going from the predominantly nocturnal margay (Leopardus wiedii) to the predominantly diurnal jaguarundi (Puma yagouaroundi), with the remaining species lying in between these two extremes.
