Abstract The physiological demands of flight exert strong selection pressure on avian morphology and so it is to be expected that the evolutionary loss of flight capacity would involve profound changes in traits. Here, we investigate morphological consequences of flightlessness in a bird family where the condition has evolved repeatedly. The Rallidae include more than 130 recognized species of which over 30 are flightless. Morphological and molecular phylogenetic data were used here to compare… 

The Evolution and Fossil Record of Palaeognathous Birds (Neornithes: Palaeognathae)

The extant diversity of the avian clade Palaeognathae is composed of the iconic flightless ratites (ostriches, rheas, kiwi, emus, and cassowaries), and the volant tinamous of Central and South

Coracoid strength as an indicator of wing-beat propulsion in birds.

According to a survey of 220 historical bird specimens representing 209 species, 180 genera, 83 families and 30 orders, the section modulus of the coracoids relative to body mass in non-flapping birds was significantly smaller than that of flapping birds, which indicates that coracoid strength in Non-Flapping birds is deemphasised, whereas in flapping Birds the strength is emphasised to withstand the contractile force produced by powerful flapping muscles.

Waxing and Waning of Wings.

Flightless birds

Richard Owen, towering figure of Victorian biology, second only to Charles Darwin, concluded that a group of bird that the authors now know as 'moa', some of which stood almost twice as tall as him and were among the largest birds that ever lived.

The endocast of the insular and extinct Sylviornis neocaledoniae (Aves, Galliformes), reveals insights into its sensory specializations and its twilight ecology

Functional interpretations suggest that S. neocaledoniae possessed a well-developed somatosensorial system and a good sense of smell in addition to its specialized visual ability for low light conditions, presumably for locating its food.

First genetic data for the Critically Endangered Cuban endemic Zapata Rail Cyanolimnas cerverai, and the taxonomic implications

It is concluded that it is unjustified to retain the monotypic genus Cyanolimnas and tentatively recommend that C. cerverai and the two Neocrex species are ascribed to genus Mustelirallus.



Patterns of correlated character evolution in flightless birds: a phylogenetic approach

It is found that pectoral reduction, pelvic enlargement and changes in skull morphology significantly co-occur, and that these are usually achieved through heterochrony rather than other kinds of developmental reprogramming.

This paper test the hypothesis that phylogenetic constraints have played a role in the evolution of flightlessness, and the effect of incorporating phylogenetic (or at least taxonomic) constraints into the analysis of habitat factors associated with flightlessness is considered.

Flightlessness affects cranial morphology in birds.

Predictable evolution toward flightlessness in volant island birds

It is found that island bird species have evolved smaller flight muscles than their continental relatives, and this pattern was consistent across nine families and four orders that vary in lifestyle, foraging behavior, flight style, and body size.

Genetic tests of rapid parallel speciation of flightless birds from an extant volant ancestor

The present study provides the first test of this model of speciation using genetic data sampled throughout the range of a putative ancestral species, and indicates that G. philippensis is polyphyletic, but is not the ancestor of most of its flightless congeners, as previously thought.

Phylogenomic evidence for multiple losses of flight in ratite birds

A phylogenetic analyses of 20 unlinked nuclear genes reveal a genome-wide signal that unequivocally places tinamous within ratites, making ratites polyphyletic and suggesting multiple losses of flight.

Form and Function in Avian Flight

This chapter explores how the mechanics of flapping flight have molded the flight adaptations of birds and uses a multivariate analysis of wing morphology to demonstrate how these constraints interact to different degrees in different birds and underlie correlations among flight morphology, ecology, and behavior.

High flight costs, but low dive costs, in auks support the biomechanical hypothesis for flightlessness in penguins

The hypothesis that function constrains form in diving birds is supported, and that optimizing wing shape and form for wing-propelled diving leads to such high flight costs that flying ceases to be an option in larger wing- Propelled diving seabirds, including penguins.

Speciation of Flightless Rails on Islands: A DNA-Based Phylogeny of the Typical Rails of the Pacific

A locally calibrated relaxed molecular clock indicates that species from Oceania evolved only within the last 400,000 years, supporting the hypothesis that speciation proceeds rapidly in flightless rails and resolving a long-standing taxonomic quagmire.

Evolution of the rails of the South Atlantic islands (Aves: Rallidae)

Flightlessness in rails is shown to be a neotenic condition that involves only the control of relative growth of body parts, is evolved at a rapid rate, and therefore has limited taxonomic significance.
