Plate-billed Mountain-Toucans inhabit a restricted range and are listed as near threatened. They are threatened both by deforestation and subsequent habitat loss, and by illegal capture for the pet trade. These toucans inhabit humid and wet montane forests and secondary growth where they are partial to areas filled with bromeliads, mosses, and epiphytes. They mostly forage on a large variety of fruits but nestlings are also fed insects, eggs, birds, rodents, or snails. During times of limited fruit availability, groups of birds tend to leave their home range. The yellow rectangular plate on the upper bill helps differentiate this toucan from most others.
