Parrots (traditional order Psittaciformes) are one of the most instantly recognizable groups of modern birds. Their relatively large heads, squat necks and broad, curved bills help to make parrots so easily identifiable. However, the few early fossil parrots that have been discovered to date (Lower Eocene), do not necessarily possess this “parrot-like” cranial morphology. Even more surprisingly, early psittaciforms have mainly been found in the northern hemisphere (Walton-on-the-Naze, England… Expand
Stem Parrots (Aves, Halcyornithidae) from the Green River Formation and a Combined Phylogeny of Pan-Psittaciformes
TLDR
Fossil evidence is consistent with a more recent origin of crown clade Psittaciformes than predicted from divergence dating analyses, and supports environmental shifts and dispersal as key drivers in parrot biogeography. Expand
An Early Miocene Diversity of Parrots (Aves, Strigopidae, Nestorinae) from New Zealand
TLDR
High degree of endemism strongly suggests that the Zealandian terrestrial biota persisted, at least in part, through the Oligocene highstand in sea level, adding to the growing body of evidence that the New Zealand terrestrial vertebrate fauna was highly endemic. Expand
Skull morphometric characters in parrots (Psittaciformes)
TLDR
A geometric morphometric approach was used to analyse two-dimensional cranial landmarks and dietary categories overlap in the morphospace but the analysis in lateral and ventral view resulted in significant differences. Expand
TWO NEW PARROTS (PSITTACIFORMES) FROM THE LOWER EOCENE FUR FORMATION OF DENMARK
TLDR
Two new fossil psittaciform birds from the Lower Eocene 'Mo Clay' (Fur Formation) of Denmark (c. 54 Ma) are described and one (Mopsitta tanta gen. et sp. nov.) is the largest fossil parrot yet known. Expand
The evolutionary history of cockatoos (Aves: Psittaciformes: Cacatuidae).
TLDR
A detailed multi-locus molecular phylogeny of cockatoos is investigated and it is clear that many of the cockatoo species' diagnostic phenotypic traits have evolved in parallel or convergently across lineages. Expand
The multifactorial nature of beak and skull shape evolution in parrots and cockatoos (Psittaciformes)
TLDR
It is proposed that allometry and integration are important factors causing canalization of the avian head, and while diet clearly has an influence on beak shape between families, this may not be as important at driving evolvability within families as is commonly assumed. Expand
Phylogenetic Relationships of the Extinct Carolina Parakeet (Conuropsis carolinensis) Inferred from DNA Sequence Data
TLDR
The first DNA sequences from the extinct Carolina Parakeet were obtained and used to infer the phylogenetic relationships of this iconic North American parrot, and it is recommended that continued recognition of the monotypic genus Conuropsis is recommended. Expand
A new time tree reveals Earth history’s imprint on the evolution of modern birds
TLDR
P pervasive evidence is found that avian evolution has been influenced by plate tectonics and environmental change, two basic features of Earth’s dynamics. Expand
Toward resolving deep neoaves phylogeny: data, signal enhancement, and priors.
TLDR
Improved conditional down-weighting techniques to reduce noise relative to signal for deeper divergences and find increased agreement between data sets are described and form a basis for further testing with both nuclear-coding sequences and rare genomic changes. Expand
Jaw myogenesis in the monk parakeet: evidence of developmental reprogramming in the emergence of novel muscles in Psittaciformes (Aves).
TLDR
The results suggest that in M. monachus the muscles EM and PM emerge as a result of a process of heterotipy, and variations in the degree of development of the PM are associated to a heterochronic process of post-displacement, with M.monachus having an underdeveloped PM with respect to basal Psittaciformes.

TLDR
This study provides the first detailed survey on the variation of hypotarsus mor- phology within extant Psittaciformes and describes a derived hypotarsal structure that supports monophyly of a clade including the genera Psephotus, Eunymphicus, Cyanoramphus, Northiella, Prosopeia, Barnardius, Platycercini, and Melopsittacus.

A new family of Eocene zygodactyl birds
TLDR
The Pseudasturidae, a new family of small Lower to Middle Eocene zygodactyl birds is described in the Middle Eolithic of Grube Messel, near Darmstadt (Hessen, Germany), and the presence of large processus supraorbitales, which closely resemble the corresponding structures found in falconiform birds is characteristic.

On the osteology and phylogenetic affinities of the Pseudasturidae–Lower Eocene stem-group representatives of parrots (Aves, Psittaciformes)
TLDR
Derived osteological characters which are visible in newly recognized specimens from the Lower Eocene London Clay of England most convincingly support classification of the Pseudasturidae into the Psittaciformes (parrots). Expand
