Aim  Parrots are thought to have originated on Gondwana during the Cretaceous. The initial split within crown group parrots separated the New Zealand taxa from the remaining extant species and was considered to coincide with the separation of New Zealand from Gondwana 82–85 Ma, assuming that the diversification of parrots was mainly shaped by vicariance. However, the distribution patterns of several extant parrot groups cannot be explained without invoking transoceanic dispersal, challenging… 

Diversity versus disparity and the role of ecological opportunity in a continental bird radiation

Arini show signs of an early adaptive radiation, but the lack of diversity-dependent speciation might be a general feature of adaptive radiations on a continental scale, and diversification processes on continents might not be as ecologically limited as in isolated lakes or on oceanic islands.

Diversification patterns in the North Andean Block: a perspective from biogeographical hypotheses

This work has assessed four hypotheses that explain the diversification in the NAB: three sets of unequal rates of dispersal between areas and a temporal stratification, containing four-time intervals for the Miocene.

Southern hemisphere tectonics in the Cenozoic shaped the pantropical distribution of parrots and passerines

Explanations of pantropical distributions are challenging for taxa that diverged during the Cenozoic, after Gondwana broke apart. The ‘boreotropics hypothesis’ suggests that pantropical birds

The timing of diversification within the most divergent parrot clade

New psittaciform DNA sequence data is examined, and previously published sequences are combined to shed light on the poorly understood timing of diversifi cation within the Strigopidae, showing a Late Pliocene or Early Pleistocene divergence between the two Nestor species.

In and out of Mesoamerica: temporal divergence of Amazilia hummingbirds pre‐dates the orthodox account of the completion of the Isthmus of Panama

We used mitochondrial DNA sequences to reconstruct the phylogenetic relationships of Mesoamerican Amazilia hummingbirds (Trochilidae). The phylogeny was used to identify vicariance scenarios,

Parrots of Oceania – a comparative study of extinction risk

ABSTRACT Australia, New Zealand, New Guinea, Wallacea, and the islands of the Pacific Ocean collectively possess 42% of the world’s parrot species, including half of all Critically Endangered

New Zealand Passerines Help Clarify the Diversification of Major Songbird Lineages during the Oligocene

Dating analyses of this robust phylogeny suggest Passeriformes originated in the early Paleocene, with the major lineages of oscines “escaping” from Australasia about 30 Ma, and radiating throughout the world during the Oligocene.

Advancing Genetic Methods in the Study of Parrot Biology and Conservation

It is shown that the application of genetic techniques to the study of parrot biology has far-reaching implications for addressing diverse research aims in a highly threatened and charismatic clade of birds.

Phylogenetic evidence for mid-Cenozoic turnover of a diverse continental biota

Molecular phylogenetic data is used to show mid-Cenozoic restructuring of Australia’s lizards and snakes and indicates that the temporal clustering of major radiation ages in Gondwanan endemic lineages and immigration into Australia is narrower than expected under time-continuous models assuming no overarching external perturbation.

Resolving a phylogenetic hypothesis for parrots: implications from systematics to conservation

An overview of published genetic data of parrots, characterise sampling depth across the phylogeny, and evaluate support for existing systematic treatments reveal well-supported relationships among recently proposed clades.



Historical biogeography and diversification within the Neotropical parrot genus Pionopsitta (Aves: Psittacidae)

This work investigates spatial and temporal patterns of diversification within the Neotropical avifauna using the phylogenetic history of parrots traditionally belonging to the genus Pionopsitta Bonaparte 1854, which encompasses species that occur in most Neotropic forest areas of endemism.

The assembly of montane biotas: linking Andean tectonics and climatic oscillations to independent regimes of diversification in Pionus parrots

Phylogenetic and biogeographic analyses of species in the parrot genus Pionus are used to demonstrate that standing diversity within montane lineages is directly attributable to events of Earth history, and support a mechanistic link between diversification and Earth history.

The evolutionary diversification of parrots supports a taxon pulse model with multiple trans-oceanic dispersal events and local radiations.

Explosive Evolution in Tertiary Birds and Mammals

The traditional view of avian evolution over the past century is that of sluggish gradualism, in which many living orders of birds are thought to have originated from the mid-Cretaceous or so (1),

Goodbye Gondwana? New Zealand biogeography, geology, and the problem of circularity.

is the perceived role of plate tectonics in mediating the widespread "Gondwanan" distribution of taxa currently limited to southern landmasses such as Africa, South America, Australia, New Zealand,

Biogeographical history of cuckoo‐shrikes (Aves: Passeriformes): transoceanic colonization of Africa from Australo‐Papua

Improved taxon sampling and analyses within an explicit spatiotemporal framework are elucidated to elucidate biogeographical patterns of dispersal and diversification within this diverse clade of passerine birds.

Mass Survival of Birds Across the Cretaceous- Tertiary Boundary: Molecular Evidence

Data for several other terrestrial vertebrate groups indicate a similar pattern of survival and, taken together, favor incremental changes during a Cretaceous diversification of birds and mammals rather than an explosive radiation in the Early Tertiary.

Population structure and biogeography of Hemiphaga pigeons (Aves: Columbidae) on islands in the New Zealand region

The population structure and phylogeography of Hemiphaga across islands in the region is examined, finding that extinction at the population and species levels could yield the same pattern.

The delayed rise of present-day mammals

The results show that the phylogenetic ‘fuses’ leading to the explosion of extant placental orders are not only very much longer than suspected previously, but also challenge the hypothesis that the end-Cretaceous mass extinction event had a major, direct influence on the diversification of today’s mammals.
