They usually prowl about at night, are difficult to detect, and merge with the background landscape. Researchers often depend on indirect signs that these animals leave behind, such as footprints, to detect them in forests. But footprints may not be so reliable after all, warns a study recently published in Mongabay’s open-access journal Tropical Conservation Science. Researchers from Brazil and Portugal took measurements of front and hind footprints of several captive individuals of four wild cat species found in Brazilian rainforests — jaguarundi (Puma yagouaroundi), ocelot (Leopardus pardalis), oncilla (Leopardus guttulus), and margay (Leopardus wiedii) — and compared them to those of domestic cats. With the exception of the ocelot, the team found that size and shape of footprints of all the wild cat species as well as the domestic cats were similar. “From our data it was impossible to distinguish small felids based on footprint total size and pad size, and configuration as well,” the researchers write in the paper. “This limitation is enhanced in field studies because it is impossible to distinguish between front and hind footprints in such conditions.” Wild felid species tested in the present study and some examples of footprints printed in sand. A – Ocelot (Leopardus pardalis); B – Ocelot footprint; C – Jaguarundi (Puma yagouaroundi); D – Jaguarundi footprint; E…
