guan

The 'true' (Penelope) guans also occur at a range of altitudes but like most species of cracids, are mostly restricted to forest, both montane and lowland. Piping-guans (Pipile) are primarily lowland species, whereas numerous monospecific (single-species genus) taxa of guans (i.e. Aburria, Penelopina, Oreophasis) are restricted to montane environments.
