Did You Know?Did You Know?

Ocelots in central Panama seem to be more successful at hunting larger prey than ocelots in other regions. Research of ocelot fecal deposits documented the diets of these animals on Barro Colorado Island and in mainland central Panama and compared them to diet studies performed at seven other sites. Results showed that the Panamanian ocelots ate more medium-size prey (agoutis, sloths, iguanas) than the seven ocelot populations studied in sites with healthy jaguar populations. Those ocelot populations generally fed on small rodents and other mammals weighing less than a kilogram (2.2 pounds). The near absence of jaguars in central Panama gives its ocelots—and pumas—better opportunities to eat larger prey.
