Journal ArticleDOI
Structural absorption by barbule microstructures of super black bird of paradise feathers
TL;DR: Physical structure is known to contribute to the appearance of bird plumage through structural color and specular reflection, but a third mechanism, structural absorption, leads to low reflectance and super black color in birds of paradise feathers.
Journal ArticleDOI
Barb geometry of asymmetrical feathers reveals a transitional morphology in the evolution of avian flight
TL;DR: The findings suggest that the fully modern avian flight feather, and possibly a modern capacity for powered flight, evolved crownward of Confuciusornis, long after the origin of asymmetrical flight feathers, and much later than previously recognized.
Journal ArticleDOI
The Anna's hummingbird chirps with its tail: a new mechanism of sonation in birds.
TL;DR: High-speed video of diving birds, experimental manipulations on wild birds and laboratory experiments on individual feathers are used to show that the dive sound is made by tail feathers, and a flag model is proposed to explain the feather's fluttering and accompanying sound.
Journal ArticleDOI
How flight feathers stick together to form a continuous morphing wing.
Laura Y. Matloff,Eric I. Chang,Teresa J. Feo,Lindsie Jeffries,Amanda K. Stowers,Cole Thomson,David Lentink +6 more
TL;DR: It is found that the hooked microstructures fasten feathers across bird species except silent fliers, whose feathers also lack the associated Velcro-like noise, which could inspire innovative directional fasteners and morphing aircraft.
Journal ArticleDOI
Why Do Calypte Hummingbirds Sing with Both Their Tail and Their Syrinx? An Apparent Example of Sexual Sensory Bias
TL;DR: The “sexual sensory bias” hypothesis is proposed as an explanation for the match in form between the song and the dive‐sound within each species, in which it is suggested that new sexual signals can arise in response to preexisting female preferences for older sexual signals.
