Graydidascalus View in CoL

Graydidascalus brachyurus View in CoL occurs throughout the Amazonian floodplains and is a midsized, predominantly green stocky parrot with black lores, prominent red iris, very short tail, and unusually large bill. As with many other Amazonian birds of floodplains, it is taxonomically monotypic having no described geographic variation ( Forshaw, 1973; Remsen and Parker, 1983), yet it may contain uncharacterized genetic structuring along rivers ( Thom et al., 2020). Graydidascalus brachyurus View in CoL shares a common ancestor with Alipiopsitta xanthops View in CoL 7.8 Mya (4.1–10.4), reflecting a long period, in both taxa, during which taxonomic or geographic variation did not accumulate.
