Avian Evolution: How Raptor Limbs Became Bird Wings
2013-09-18 06:09:13

April Flowers for redOrbit.com - Your Universe Online Scientists are certain that sometime around 150 million years ago birds originated from a group of small, meat-eating theropod dinosaurs called maniraptorans. According to recent studies conducted around the world, the maniraptorans were very bird-like, with feathers, hollow bones, small body sizes and high metabolic rates. What remains unclear is at what point the forelimbs evolved into wings, making it possible for the maniraptorans...

Songbirds Risk Missing Peak Food Supply Says Study
2013-06-03 13:45:42

York University A mismatch between the departure schedules of songbirds and higher spring temperatures at their breeding sites is putting them at risk, according to a new study out of York University. The study, "A Trans-Hemispheric Migratory Songbird Does Not Advance Spring Schedules or Increase Migration Rate in Response to Record-Setting Temperatures at Breeding Sites", published in the journal PLOS ONE, tracked the spring migration of purple martins over five years from the Amazon...

New Fossil Helps Explain Evolution Of Hummingbird Flight
2013-05-01 13:38:41

Brett Smith for redOrbit.com - Your Universe Online According to a recently published study in“¯Proceedings of the Royal Society B, a small bird fossil found in Wyoming could be the link that connects the evolutionary dots between hummingbirds and swifts. Because the fossil had unusually well-preserved feathers, the scientists said they were able to create an approximate reconstruction that would not have been possible with fossilized bones alone. "This fossil bird...

Researchers Discover New Migration Habits Of Manx Shearwater Seabird
2013-05-01 10:35:22

Brett Smith for redOrbit.com - Your Universe Online Using cutting-edge tracking devices and data analysis techniques, a group of UK researchers has discovered new migration habits of the Manx Shearwater, a small seabird. Scientists at the University College London (UCL) and the University of Oxford collected data over three consecutive years to reveal the birds´ complex pattern of rest, flight and foraging, according to their report in journal Interface. "Understanding the...

Robotic Bat Wing Created By Brown University Team
2013-02-22 06:10:26

[ Watch the Video: Researchers Build A Robotic Bat Wing ] April Flowers for redOrbit.com - Your Universe Online Searching for the secrets of bat flight, researchers have built a robotic bat wing which mimics the wing shape and motion of the lesser dog-faced fruit bat. The wing is designed to flap when attached to a force transducer - which records the aerodynamic forces generated by the moving wind - in a wind tunnel. Researchers can then evaluate the energy required to execute wing...

Migrating Birds Delayed By Drought In The Horn Of Africa
2012-12-07 15:03:24

University of Copenhagen The catastrophic drought last year in the Horn of Africa affected millions of people but also caused the extremely late arrival into northern Europe of several migratory songbird species, a study from University of Copenhagen published today in Science shows. Details of the migration route was revealed by data collected from small back-packs fitted on birds showing that the delay resulted from an extended stay in the Horn of Africa. The extensive 2011 drought in...

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...

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...
