This scenario is based on the kea, the world's only alpine parrot.
Even though it eats plants like other parrots, it also eats meat, and therefore could be New Zealand's answer to the smaller diurnal raptors like hawks or falcons. But what if predatory psittaciform birds were global?
Is the shape of the kea the ideal archetype of a predatory parrot in an alternate Earth where neither Accipitriformes nor Falconiformes exist? Or would the parrots need to have body plans identical to hawks, vultures, condors, eagles, harriers and kites to parallel their niches?
