“…This conclusion is in general agreement with a hypothesis on the vicariant origin of parrots mediated by the breakup of Gondwanaland (Cracraft, 1973(Cracraft, , 2001Schweizer et al, 2010;Wright et al, 2008).…”

“…Molecular genomic results seem to indicate an Eocene divergence of Psittaciformes in three basal lineages (Pacheco et al, 2011;Rheindt et al, 2014;Schweizer et al, 2010Schweizer et al, , 2011Tavares, Baker, Pereira, & Miyaki, 2006;Wright et al, 2008), which correspond to the most recent taxonomical classification of the order in three families; Strigopidae, Cacatuidae and Psittacidae (Winkler et al, 2015).…”

“…Today, even if the fossil record has not yet supported this hypothesis (54 MY old, early Eocene Mopsitta tanta represents the oldest parrot fossil found to date (Waterhouse, Lindow, Zelenkov, & Dyke, 2008)), phylogenetic analysis and molecular clock estimates, confronted to the paleogeographical events, indicate that parrots have originated in Gondwanaland during the Cretaceous, and it is generally agreed that most of the diversification of the group took place in Cenozoic Palaeogene times (Ericson, 2012;Schweizer, Seehausen, Güntert, & Hertwig, 2010;Wright et al, 2008). This conclusion is in general agreement with a hypothesis on the vicariant origin of parrots mediated by the breakup of Gondwanaland (Cracraft, 1973(Cracraft, , 2001Schweizer et al, 2010;Wright et al, 2008).…”

“…However, there are some difficulties in establishing the temporal and causal relationships between geological and biological events (Wright et al, 2008), and vicariance alone cannot explain the distribution patterns of several parrot groups, neither the divergence time estimates among taxa (Kundu, Jones, Prys-Jones, & Groombridge, 2012;Schweizer et al, 2010).…”

“…Early divergence of New Zealand Strigopidae parrots: kea (Nestor notabilis), kaka (Nestor meridionalis) (Tribe Nestorini) and kakapo (Strigops habroptilus) (Tribe Strigopini), has been (not unanimously) correlated to the Cretaceous separation of New Zealand from Gondwana 82-85 MYA (Pacheco et al, 2011;Rheindt et al, 2014;Schweizer et al, 2010Schweizer et al, , 2011Tavares et al, 2006;Wright et al, 2008), and it was cautiously assumed to be caused by vicariance (de Kloet & de Kloet, 2005;Wright et al, 2008), although alternative scenarios are contemplated (Pacheco et al, 2011;Rheindt et al, 2014;Schweizer et al, 2011;White et al, 2011).…”

With colourful plumage, charismatic character and vocal learning abilities, parrots are one of the most striking and recognizable bird groups. Their attractiveness has drawn human attention for centuries, and members of the Psittaciformes order were, also, among the first avian species to be subject to cytogenetic studies which have contributed to understand their taxonomic and evolutionary relationships.We present here the karyological results collected by the study of thirteen parrot species new to karyology. These results are additionally supported by G banded preparations obtained in five species.The order Psittaciformes is an interesting example of a, typically, non migratory avian lineage with Gondwanaland origin, whose evolutionary radiation has been shaped by the Cenozoic geographic and climatic events that affected the land masses derived from the Gondwanaland continental split.We discuss the results of our studies, in conjunction with the previously compiled Psittaciformes cytogenetic data to delineate a picture of the chromosomal evolution of the order, concurrently with the biogeographic history of the lands in the southern Hemisphere.Considering the available data on parrot cytogenetics, a "standard parrot karyotype pattern" is proposed for evolutionary comparisons.Several biogeographic, and phylogenetically related "karyogram patterns" are also identified, and mechanisms of chromosome rearrangement that associate this patterns among them, and with the standard parrot karyotype pattern are proposed. These schemes on parrot chromosomal variation are discussed in relation to the general avian chromosome evolutionary theses proposed by cytogenetic and molecular genomic researchers.

Specialization to nectarivory is associated with radiations within different bird groups, including parrots. One of them, the Australasian lories, were shown to be unexpectedly species rich. Their shift to nectarivory may have created an ecological opportunity promoting species proliferation. Several morphological specializations of the feeding tract to nectarivory have been described for parrots. However, they have never been assessed in a quantitative framework considering phylogenetic nonindependence. Using a phylogenetic comparative approach with broad taxon sampling and 15 continuous characters of the digestive tract, we demonstrate that nectarivorous parrots differ in several traits from the remaining parrots. These trait-changes indicate phenotype–environment correlations and parallel evolution, and may reflect adaptations to feed effectively on nectar. Moreover, the diet shift was associated with significant trait shifts at the base of the radiation of the lories, as shown by an alternative statistical approach. Their diet shift might be considered as an evolutionary key innovation which promoted significant non-adaptive lineage diversification through allopatric partitioning of the same new niche. The lack of increased rates of cladogenesis in other nectarivorous parrots indicates that evolutionary innovations need not be associated one-to-one with diversification events.
