Swifts Don’t Just Dream of Flying…

…they fly while dreaming.  Did you know that swifts, the aerial acrobats of the air, sleep on the wing?  That’s not all, they adapt their wing shape to turn on a dime.  Science Daily summarized the cover story of Nature this week (April 26) that examined “wing morphing” in swifts – their ability to change […]

Scientists Track Homing Pigeons with GPS

How do homing pigeons find their way?  Scientists are still not sure.  They know that the birds use a sun compass and magnetic fields, but what other cues guide them back to the specific roost they know as home?  A new study shows they are smarter than we thought.  They use multiple cues and weigh […]

The Amazing Pigeon Techno-Beak

How do homing pigeons find home?  Scientists at University of Frankfurt may have found the answer: magnetic minerals in their beaks.  A press release from Springer Publications describes the amazing pigeon techno-beak: In histological and physicochemical examinations in collaboration with HASYLAB, the synchrotron laboratories based in Hamburg, Germany, iron-containing subcellular particles of maghemite and magnetite […]

Evolutionary Predictions Fail Observational Tests

Lately, some expectations by evolutionists have not been fulfilled.  Here are several recent examples of evolutionary upsets: Dinobird genes cook up scrambled eggs:  Scientists expected that the dinosaurs presumed ancestral to birds would show a decreasing genome size.  The thinking was that the cost of maintaining a large genome takes its toll on flight.  In […]

Woodpecker Heads Absorb Shocks

Pounding a tree with your head 12,000 times a day would tend to give one a headache, but for woodpeckers, it’s all in a day’s work.  How do they manage?  Corey Binns on Live Science interviewed Ivan Schwab (UC Davis) who explained some of the specialized adaptations in a woodpecker head: thick muscles, spring-like bones, […]
