Psittacopasserae

Psittacopasserae is a taxon of birds consisting of the Passeriformes (passerines, a large group of perching birds) and Psittaciformes (parrots). Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising passerines, psittacines and Falconiformes.[3] The group was proposed following an alignment of nuclear intron sequences by Shannon Hackett et al. in 2008.[4] It was formally named in a 2011 Nature Communications article by Alexander Suh and other authors working with Jürgen Schmitz's group,[5] based on genetic analysis of the insertion of retroposons into the genomes of key avian lineages over the course of evolution during the Mesozoic Era.

Significance in the evolution of birdsong

Passerines are renowned as songbirds, and parrots share a capacity for vocal learning. Thus it is possible that vocal learning, and the corresponding variety of song, was present in a psittacopasseran ancestor.[5]
