A "Perverted" View of Bird Evolution
Among the many recurring themes on this blog, the evolution of birds from feathered maniraptoran dinosaurs is probably the most prevalent.

Cats Defy Gravity to Take a Sip
The 1940 documentary short "Quicker'n a Wink" fascinated people with its slow-motion imagery of things like the beating of a hummingbird's wings; it won a 1941 Academy Award. One of the revelations from the movie was that a cat curls its tongue backwards into a "J" when it goes to take a drink of l...

Pink Flamingoes Attract Mates With Make-Up
The flamingo's bright pink coloration comes from its diet—animals can't synthesize the carotenoids that color these feathers. The more carotenoid-containing food a flamingo eats before molting and growing new feathers, the brighter those feathers will be. Over time, though, the color fades. So how ...

Tracking the Emergence of Birds
Since the description of the fuzzy-feathered dinosaur Sinosauropteryx in 1996, paleontologists have been inundated with a still-flowing flood of fossil evidence confirming that birds are living dinosaurs. More than that, many of the characteristics we once thought were unique to birds—from air-sacs...

Photo Contest Finalist: Chinstrap Penguins Climbing an Iceberg
Most everyone here in D.C. would prefer to forget the Snowpocalypse of 2010, but with autumn upon us, winter—and the weather that comes with it—is just around the corner. Don’t get me wrong: snow is quite pretty when it’s freshly fallen. But at this point I’d just as soon admire the stuff from afar...

It's Hawk Watch Season
It's the most wonderful time of the year—fall bird migration.Spring migration is nice, too, when birds are in their brightest breeding plumage (see the difference between spring and fall colors in a chestnut-sided warbler).

Gargantuan Spider Webs Bridge Waters of Madagascar
As a young girl, I used to wake up in the middle of the night, frightened by a spider I knew had to be lurking in some dark corner of my room. For arachnophobes such as myself, nothing could be more unsavory than a big spider that blends seamlessly into tree bark. Unless that same spider also spins...

It's All in the Hips: the Feathered Dinosaur Microraptor
Ever since the announcement of an exquisitely-preserved specimen of the feathered dinosaur Microraptor gui in 2003, paleontologists have been debating how it might have flown and what relevance it might have to the origin of birds. How did it hold its legs? Could it really fly, or just glide? Is is...

Why Some Kitties Meow and Others Roar
Members of the cat family (Felidae) are nearly all lone creatures and use meows and roars to communicate to potential mates over long distances. (Lions are the exceptions; they're the only social kitty species.) Scientists have wondered why some calls are high pitched—like your housecat's meow—or d...

Florida Panthers Helped by Texas Cats
Call them panthers, mountain lions, cougars or pumas, the Americas' largest cat species has been dwindling in eastern North America for hundreds of years. They were extirpated from everywhere but some shrinking habitat in Florida between Naples and Miami. And even there, the panthers were not doing...

Hares Can Get Pregnant While Pregnant
The idea that you could conceive a second pregnancy while already pregnant is definitely weird (and probably creepy for any woman in her last trimester). This is all but impossible in humans, but what about other species? Aristotle suggested more than two thousand years ago that the hare—the rabbit...
