Tityridae

Tityridae is family of suboscine passerine birds found in forest and woodland in the Neotropics. The 45 species in this family were formerly spread over the families Tyrannidae, Pipridae and Cotingidae (see Taxonomy). As yet, no widely accepted common name exists for the family, although tityras and allies and tityras, mourners and allies have been used. They are small to medium-sized birds. Under current classification, the family ranges in size from the buff-throated purpletuft, at 9.5 cm (3.7 in) and 10 grams (0.35 ounces), to the masked tityra, at up to 24 cm (9.5 in) and 88 grams (3.1 ounces). Most have relatively short tails and large heads.

Taxonomy and systematics

The family Tityridae (as the subfamily Tityrinae) containing the genera Tityra and Pachyramphus was introduced by the English zoologist George Robert Gray in 1840.

Traditionally, the genus Laniocera was included in the family Tyrannidae, the genera Iodopleura, Laniisoma, Tityra, Pachyramphus and Xenopsaris were included in the family Cotingidae, and Schiffornis was included in the family Pipridae. Three of these genera, Tityra, Pachyramphus and Xenopsaris, were later moved to Tyrannidae based on the morphology of their skull and syrinx.

The existence of the family Tityridae (although simply treated as a clade) was first proposed in 1989 based on the morphology of several syringeal and skeletal features. The existence of this family has later been confirmed by multiple studies involving both mitochondrial DNA and nuclear DNA.

The cladogram below shows the phylogenetic relationships in the parvorder Tyrannida. It is based on the study by Carl Oliveros and collaborators published in 2019 and the study by Michael Harvey and collaborators that was published in 2020. The families and species numbers are from the list maintained by the International Ornithologists' Union (IOC).

Species

The family contains 37 species divided into 7 genera:
