Phylogenetic relationships of the Papuan Swiftlet Aerodramus papuensis and implications for the evolution of avian echolocation

  author={J. Jordan Price and Kevin P. Johnson and Sarah E. Bush and Dale H. Clayton},
The swiftlets (genera Aerodramus , Collocalia and Hydrochous ) are unusual among birds in that many species can orientate in complete darkness using echolocation. The position of the Papuan Swiftlet Aerodramus papuensis in this group has been uncertain historically, in part due to morphological differences between it and other swiftlets (it has three toes instead of the usual four) and a lack of data on its behaviour (there is uncertainty about whether it echolocates). Here we investigate the…

Phylogenetic relationships of the Eastern Polynesian swiftlets (Aerodramus, Apodidae) and considerations on other Western Pacific swiftlets

ABSTRACT The patterns of colonisation and phylogenetic relationships of the swiftlets from Oceania, and in particular from the remotest archipelagos of Polynesia, remain a puzzle. In this study we

A morphological revision of Mascarene Swiftlet Aerodramus francicus, with the description of a new subspecies from Reunion

Summary. In light of speculation in the recent literature concerning the species' intraspecific taxonomy and personal observations, we examined specimens of the Mascarene Swiftlet Aerodramus

Extensive diversifi cation across islands in the echolocating Aerodramus swiftlets

It is suggested that the genus Aerodramus, a group of echolocating swiftlets that has diversified throughout the Indo-Pacifi c region, may be considered a "great speciator", which has undergone a recent rapid radiation involving the colonisation of most islands in the Indian and Pacifi c oceans.

Total-Evidence Framework Reveals Complex Morphological Evolution in Nightbirds (Strisores)

It is suggested that multiple strisorean lineages have experienced convergent evolution across the skeleton, obfuscating the phylogenetic position of certain fossils, and that many distinctive specializations ofstrisorean subclades were acquired early in their evolutionary history.

So similar and yet so different: taxonomic status of Pallid Swift Apus pallidus and Common Swift Apus apus

Differences in breeding biology, migration, moult and vocalizations between the two species are mirrored by a clear genetic separation that dates back to 1.9–2.1 mya at the Plio-Pleistocene transition, when global climate underwent a period of significant cooling and Northern latitudes were probably more favourable to the Common than to the Pallid Swift.

Introduction to the Skeleton of Hummingbirds (Aves: Apodiformes, Trochilidae) in Functional and Phylogenetic Contexts

This monograph deals with the syrinx and with skeletal features mainly associated with nectarivory and hovering, emphasizing characters that are unique to hummingbirds within Apodiformes.

Observations on the behavioural ecology of the Atiu Swiftlet Aerodramus sawtelli

The Atiu Swiftlet Aerodramus sawtelli is endemic to the Cook Island of Atiu and has an estimated total population of less than 400, rendering it one of the world’s most globally endangered bird

Skeletal morphology of the middle Eocene swift Scaniacypselus and the evolutionary history of true swifts (Apodidae)

The less specialized wing and pectoral girdle morphology suggests that Scaniacypselus was probably not as aerial as extant Apodidae, and the differences in foot morphology indicate that it was more arboreal than its living relatives and had different breeding and roosting habits.

Reweaving the Tapestry: a Supertree of Birds

This is a first attempt at a supertree of both extinct and extant birds, not intended to be utilised in an overhaul of avian systematics or as a basis for taxonomic re-classification but provides a strong basis on which to base further studies on macroevolution, conservation, biodiversity, comparative biology and character evolution.



Does behavior reflect phylogeny in swiftlets (Aves: Apodidae)? A test using cytochrome b mitochondrial DNA sequences.

An independent phylogeny using cytochrome b mitochondrial DNA sequences from swiftlets and their relatives is constructed, which is broadly consistent with the higher classification of swifts but does not support the monophyly of swiftlets.

The evolution of echolocation in swiftlets

A well-supported molecular phylogeny is presented for the swiftlets and their relatives based on DNA sequence data from two mitochondrial genes, which are used to reconstruct the evolution of echolocation and provide strong evidence that the swiftlet group are amonophyletic group.

Echolocation and the systematics of swiftlets

During his period of interest in swifts, David Lack drew attention to the importance of nesting behaviour and nest type as guides to the systematics of the Apodidae, and sound spectrograms have been published of the orientation clicks of six taxa, representing four species.

Acuity of Echolocation in Collocalia hirundinacea (Aves: Apodidae), With Comments on the Distributions of Echolocating Swiftlets and Molossid Bats

The acuity of echolocation in Collocalia hirundinacea was studied by observing the birds' performances in an obstacle course constructed 10 m inside the mine they used as a roost and their performances in the obstacle course were very similar to previous reports for the closely relatedCollocalia vanikorensis.

Character state mapping reconstructs monochromatic ancestors for the genus Anas as well as most of its main clades and cautions against the uncritical use of unordered parsimony as the sole criterion for inferring ancestral states.

Echolocation in free-flying Atiu Swiftlets (Aerodramus sawtelli)

Spectral analyses indicate that the birds do not adjust the peak frequencies of their calls as they fly within the cave and it is suggested the bird does not systematically structure the frequency content of its calls.

The physiology of vocalization by the echolocating oilbird,Steatornis caripensis

Oilbirds have a bilaterally asymmetrical bronchial syrinx with which they produce echolocating clicks and a variety of social vocalizations andMini-breaths permit oilbirds to produce click trains having a long train duration uninterrupted by a long inspiration.
