The birds can get all the energy and nutrients they need with minimal effort. But when cattle show up to graze the desert’s natural landscape, birds face changes in food supply. Some birds are happy to change their diets in response. But others, not so much. And it’s the ones set in their ways that are at the highest risk. Understanding how birds react to grazing can help researchers solve the problem of those species. Ecologists from the Argentine Arid Zones Research Institute compared soil samples from the desert’s Nacunan biosphere reserve to samples from two neighboring cattle farms. It was discovered that grass seeds — the birds’ favorites — were just one-quarter as likely to be found on the farms compared with the reserve. Next, they caught birds to see what they were eating.
