Evidence Links Birds And Dinosaurs
2012-11-21 21:16:27

Lee Rannals for redOrbit.com — Your Universe Online More evidence has emerged, published in the journal Current Biology, claiming birds are the descendants of dinosaurs. The prehistoric Archaeopteryx and bird-like dinosaurs before them had a more primitive version of a wing, according to the recent findings. Scientists are piecing together how the wing evolved, lending to evidence that gliding dinosaurs spent much of their days in the trees. "Before, it seemed that we had...

Sneaky Owls Use Stealth And Fly Silently
2012-11-20 15:58:27

Alan McStravick for redOrbit.com — Your Universe Online Researchers are learning about stealth technology from a famous winged inhabitant in nature. Would you like to know just who-who they are taking their lead from? If you guessed the owl, well the “who” clue wasn´t exactly the most difficult. The reason they are looking at the owl is for its ability to fly silently. It is able to do this because of the natural design of its plumage, which aids in noise...

Hummingbird Flight Both Adaptable And Efficient
2012-09-27 12:12:55

Brett Smith for redOrbit.com - Your Universe Online Hummingbirds are among the most impressive aviators in the animal kingdom. Beating their wings at a rate of up to 80 times per second, they can fly forward, backward, left and right with the greatest of ease. After noticing the birds flying around a feeder on his balcony, University of California at Berkeley biologist Nir Sapir decided to investigate the mechanics of this acrobatic aviator and was surprised to find that the there was...

The concentration of skyscrapers in this downtown district creates a wind tunnel favored by soaring birds during their migration south for the winter. The unique pyramid structure atop this high-rise offered an abundance of surfaces where hundreds of turkey vultures had taken up residence. Bird Barrier's Bird-Shock Flex-Track drove the birds away. Carson, CA (PRWEB) September 15, 2012 The building manager found that it was hard to miss the gathering of large birds on the building. Their...

Robot Helps Researchers Understand Evolution Of Wings
2011-10-18 12:19:29

[ Watch the Video ] Scientists from University of California - Berkeley have built a six-legged robot to help gain a better understanding of the evolution of early birds and insects. The new study showed that the origin of wings may lie in animals that dwelled in trees rather than on the ground. The researchers said the flapping wings increased the speed of the running robot by 90 percent and also enabled it to climb steeper gradients, which would be important in the development of a...

Robotic device built in New Mexico helps analyze hovering birds Hummingbirds rank among the world's largest and most accomplished hovering animals, but how do they manage it in gusty winds? A team of researchers at New Mexico State University, Los Alamos National Laboratory, Technische Universiteit Eindhoven, and Continuum Dynamics Inc. has built a robotic hummingbird wing to discover the answer, which they describe today at the American Physical Society Division of Fluid Dynamics (DFD)...

The earliest birds may have had feathers, but they were not strong enough to carry the winged creatures in flight, researchers revealed Thursday. Recent fossil discoveries show that feathers on some of the early birds, including Confuciusornis and Archaeopteryx, were too weak to support the birds in flight. While modern birds have feathers with a strong central shaft that is hollow to reduce weight, the earliest-known birds had feathers that were much thinner and more frail. Robert Nudds...

The scientists argue that flight originated above, in the trees; such animals would have been gliders A joint team from the University of Kansas and Northeastern University in China says that it has settled the long-standing question of how bird flight began. In the Jan. 25 issue of Proceedings of the National Academy of Sciences, the KU-China researchers push their research into the origins of bird flight and the early evolution of birds with decisive flight tests of a model of the...

The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE, October 3, by Alexander Vargas and colleagues at Yale University, the University of Wisconsin-Madison and Yale Peabody Museum of Natural History. Bird wings only have three fingers, having evolved from remote ancestors that, like humans and most reptiles, had five fingers. Biologists have typically used embryology to identify the evolutionary origin (homology)...

A letter published in the advanced online publication Nature has revealed new insight into the evolution of flight in birds.    The issue has remained controversial among scientists, and previous theories have usually been based on interpretations of various fossil forms.   However, this new report is based on experimental observations of young birds, and suggests wing-stroke dynamics are the key to understanding the evolution of avian flight. The research was led by...

Microraptor
2012-03-21 23:43:50

Microraptor, meaning “small thief,” is a genus of dromaeosaurid dinosaur from the Early Cretaceous Period (120 million years ago). This small, four-winged animal was first discovered in the Jiufotang Formation in Liaoning, China, with more than two dozen specimens unearthed. There are two known species of Microraptor. The type species, M. zhaoianus, has been hotly debated for years. It was initially placed in the genus Archaeoraptor before a more accurate description placed it in the...
