Psittacopasseres is a taxon of birds consisting of the Passeriformes ( passerines, a large group of perching birds) and Psittaciformes ( parrots). [3] Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising passerines, psittacines and Falconiformes. [4] The group was proposed following an alignment of nuclear intron sequences by Shannon Hackett et al. in 2008. [5] It was formally named as Psittacopasserae in a 2011 Nature Communications article by Alexander Suh and other authors working with Jürgen Schmitz's group, [6] 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.[ clarification needed]
Significance in the evolution of birdsong
Passerines are renowned as songbirds (technically this word refers to a clade of passerines), 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. [6]
