A comprehensive review of the hundreds of bird species that have become extinct over the
last 1,000 years of habitat degradation, over-hunting and rat introduction. Extinct Birds has …

The living and extinct flightless rails of the Pacific are among the most species-rich examples
of parallel evolution in vertebrates. The “typical” rails of this region comprise a diverse …

Dispersal, when accompanied by reduced gene flow and natural selection, influences
speciation rates among groups of organisms. We used molecular phylogenetics, divergence …

Five new species of recently extinct rails from two Macaronesian archipelagoes (Madeira
and Azores) are described. All the species are smaller in size than their presumed ancestor …

Data are presented on the standard energetics of six flighted and five flightless species of
rails (Aves: Rallidae). The factors influencing these data and those from three additional …

Complex features, such as vision, limbs, and flight, have been lost by many groups of
animals. Some groups of birds are more prone to loss of flight than others, but few studies …

Recently collected fossils from the late Pleistocene (Rancholabrean North American Land
Mammal Age) locality at Térapa, Sonora, México, represent 31 species of non-passerine …

The Austral Islands in French Polynesia have a depauperate land bird fauna and until
recently have been little investigated archaeologically or paleontologically to know whether …

We describe a new species of rail from the Sawmill Sink blue hole on Abaco Island in the
northern Bahamas. Known from abundant, beautifully preserved Late Pleistocene fossils …

Species are hard to define, but under all definitions they are unique. Each species can be
considered to possess a set of unique characters that comprise its feature diversity, the …
