Behavioral observation, ecological sampling, and high-throughput sequencing give researchers insight into tamarin foraging strategies and prey preferences. In South American rainforests, researchers can tell one saddle-back tamarin from another, but what’s more difficult, is to see what the squirrel-sized monkeys are putting in their mouths. Researchers are beginning to rely on their droppings to find out what bugs and other invertebrates the monkeys munch on.
