Published Online: 22 August 2019
..., while selection pressures acting on body size, which are among the most prevalent in nature, are rarely acknowledged, leading to conflicting and confusing conclusions. We address these problems by comparing brain-body relationships from across >1,000 species of birds and non-avian reptiles. Relative...

...Thomas J. Lisney; Douglas R. Wylie; Jeffrey Kolominsky; Andrew N. Iwaniuk Hummingbirds are a group of small, highly specialized birds that display a range of adaptations to their nectarivorous lifestyle. Vision plays a key role in hummingbird feeding and hovering behaviours, yet very little...

...’ of the habitat of a species. Although these relationships are well documented in many vertebrates including birds, the extent to which they hold true for species within the same avian order is not well understood. Owls (Strigiformes) represent an ideal group for the study of interspecific variation in the avian...

...Christine J. Charvet; Alexis L. Sandoval; Georg F. Striedter Adult galliform birds (e.g. chickens) exhibit a relatively small telencephalon and a proportionately large optic tectum compared with parrots and songbirds. We previously examined the embryonic origins of these adult species differences...

The total duration of experimental treatment (21 days) was identical for each cage. One male and one female from each of the three treatment groups (six birds total) were given...

Brain volumes were calculated from magnetic resonance or computed tomography images of bird heads from 27 species representing 12 orders. Correlations between brain volume and maximum...

It possesses a sensory epithelium with hair cells similar to those of the inner ear. Injection of fluorescent carbocyanine tracers into the paratympanic organ of 9- to 11-day-old...

...Jeremy R. Corfield; J.Martin Wild; Mark E. Hauber; Stuart Parsons; M.Fabiana Kubke Brain size in vertebrates varies principally with body size. Although many studies have examined the variation of brain size in birds, there is little information on Palaeognaths, which include the ratite lineage...

The organization of the song system is then compared to other parts of the avian brain and the brains of nonoscine birds...
