Migrating Birds Measure Longitude

Migrating birds are able to get back on course, even when released 1000 km east of their normal migration path.  This shows that long-distance migrating birds are capable of true bicoordinate navigation: the ability to make course corrections both in latitude and longitude.  The results of experiments, published in Current Biology,1 left the researchers baffled: […]

Did Birds Evolve Aeronautical Engineering?

Two news stories on birds may not seem to flock together.  One is about their supreme aeronautical engineering.  The other ponders when they evolved.     A story on EurekAlert and Science Daily describes how engineers are eyeing birds, bats and insects for design ideas.  The appeal is clear from the following comparisons: A Blackbird […]

Do Chicks Tell Dinosaur Tales?

For years, evolutionary biologists have battled over the origin of flight.  Did dinosaurs run along the ground and take off, or did they jump from trees?  The first idea is called the cursorial hypothesis; the latter, the arboreal hypothesis.  In 2003, Ken Dial [U Montana] had an idea: maybe watching partridge chicks could inform the […]

Dinosaur Fossil Shows Exquisite Skin Detail

More imaginary feathers on a dinosaur have been discovered.  A BBC News article shows a cartoon of a dinosaur with feathers on its arms.  This is strange, because the paper it refers to makes no claim about feathers – only that certain structures had been interpreted as feathers by some.     The original paper […]

Birdsong Olympic Training

The singing of a bird is a complex skill that takes rigorous training like that of a top athlete or musician.  Young male birds learn by imitation from their fathers, then hone their skill over months, till their song becomes crystallized in adulthood.  A paper in Nature by two scientists at UC San Francisco reported […]

Winged Migration Grows Up

Scientists used to rely on metal bands on birds’ legs to find out how they got from here to there.  Now, they can glue tiny radio transmitters to their shoulders and follow them in real time.  What happened when Princeton scientists hijacked 30 white-crowned sparrows and took them from Seattle to New Jersey?  Age has […]

Crow Cam Lets Scientists See Intelligence at Work

Ever want to fly like a bird?  Now you can do the next best thing: get a tail-feather view of what it is like to fly from branch to branch.  University of Oxford scientists attached a small video camera to the underside of a New Caledonian Crow to watch it in the wild, reported PhysOrg.  […]

Was Velociraptor a Dragon?

As if Velociraptor, the terror of Jurassic Park, was not scary enough, some scientists are now saying it was feathered.  (This, of course, does not imply it could fly after its human prey like some movie dragon.)  The latest claim in Science is based on the apparent presence of “quill knobs” on the radius bone […]

New World Record for Winged Migration

The BBC News reports that a female bar-tailed godwit flew 11,500km (almost 7200 mi) nonstop from Alaska to New Zealand.  The journey took about a week.  Observers at Massey University used electronic tags to catalog the birds’ flight.     This distance is nearly double what ornithologists used to consider an “extremely long” flight.  This […]

Dinosaurs Stretched, Shrunk and Twisted Into Birds

Size matters, thought paleontologists envisioning the evolution of birds from dinosaurs.  The old story was that dinosaurs shrunk as their arms were becoming wings.  That view has been challenged by a new fossil reported in Science.1  Alan H. Turner (American Museum of Natural History) and four others reported a “basal dromeosaurid” that was small long […]

Birds Eat Dark Moths, Therefore God Does Not Exist

Michael Majerus watched birds eat peppered moths from his window for seven years (06/25/2004), then drew his conclusions.  In a presentation to a science conference in Uppsala, Sweden on August 23, he said that the peppered moth story proves evolution, which means there is no supernatural being to save us, there is no second coming, […]

Crows Use Tools on Tools

Crows can use one tool on another to get food.  A report in Science Daily says they appear to use analogical reasoning, not just trial and error, to figure out how to manipulate objects.  They used a short stick to get a longer stick out of a toolbox in order to reach a snack too […]

It’s Not a Bird, It’s a Plane

Look to the birds of the air, and they will teach you aeronautics.  That’s what designers of the Robo-Swift did.  PhysOrg reported about a new plane that imitates a swift thing on the wing: RoboSwift is a micro airplane fitted with shape shifting wings, inspired by the common swift, one of nature’s most efficient flyers.  […]

Roadrunner and Largest Flying Bird Described from Fossils

A bird with a 23-foot wingspan was described in the BBC News.  At an estimated 155 pounds, this bird probably had to jump from a height to get airborne and likely rode on thermals.  The article says the bird rivalled in size some light airplanes.  A diagram shows the Argentinean giant with wings upwardly stretched […]

Giant Fossil Penguins Lived in Warm Waters

“Giant prehistoric penguins?  In Peru?” puzzled a reporter on Science Daily.  “It sounds more like something out of Hollywood than science,” but a fossil penguin you could look eye to eye with has been found that far north.  “We tend to think of penguins as being cold-adapted species,” said one of the discoverers,” but not […]
