 The country's abundant fruit trees, many of which bear fruit year round, are hugely important to the birds, some of whom survive on diets that consist only of one or two types of fruit.Some of the country's most notable avian species include the resplendent quetzal, scarlet macaw, three-wattled bellbird, bare-necked umbrellabird, and the keel-billed toucan.The Instituto Nacional de Biodiversidad is allowed to collect royalties on any biological discoveries of medical importance.
