They also stretch to bite off the top of grasses and tall herbs and are well-suited to browsing. They derive most if not all of their water needs from

As the common name suggests, least seedsnipes rely mostly on seeds, but they will also eat leaves and buds and as such are strictly vegetarian in their natural habitat. However, in captivity they have been known to eat mealworms. Unlike most
