Why are owls so wise? Perhaps it's because they're utter badasses.
Ferocity is essential for a bird whose frigid, spotty range extends across northeastern China, the Russian Far East and up toward the Arctic Circle, one that breeds and nests in the dead of winter, perched atop a giant cottonwood or elm tree, out in the open, in temperatures 30 degrees below zero Fahrenheit. Dr. Slaght’s colleague Sergei Surmach videotaped a female sitting on her nest during a blizzard. “All you could see at the end was her tail jutting out,” Dr. Slaght said.

Dinosaur coloration has always been a source of wild speculation. Artistic renders have ranged from the conservative (battleship grey, lizard green) to the flamboyant
, but all guesses appeared equally valid
. While there are some wonderfully preserved examples of dinosaur skin
texture, fossils have remained stubbornly monochromatic… until now. [more inside]

Bird flu update: "At this moment, birds that travel flyways in Asia, where most bird flu cases have been found, are mingling with birds that fly through North America." Officials in Kansas
warn it will arrive this fall, as those birds fly south for the winter on North American migration pathways

Electronic Biologia Centrali-Americana
is a collaboration between the Smithsonian, Missouri Botanical and Kew Gardens, the British Natural History Museum and various other institutions which has enabled the digitizing of 58 volumes of natural history about central America produced between 1880 and 1920. It includes descriptions of more than 50,000 species with images of more than 18,000 birds
, more birds
, more spiders
, more plants
, orthoptera insects
, more butterflies
and their family
and even some historic maps of the region
. There is a parallel project attempting to provide access to much more scientific data and specimens between these institutions.
Note: 'next' button at top +/- bottom of these large thumb pages; large high resolution jpegs work (in most cases) but zoom and .pdfiles are not yet enabled. I've only just scratched the surface.

) are small, colorful sparrow-sized birds found all over Central and South America. Manakin males engage in elaborate courtship dances
, including rhythmic sounds they produce with their wings. No one really knew how the birds made this sounds, until Kimberly Bostwick
, Curator of Birds and Mammals at the Cornell University
Museum of Vertebrates
, went into the jungles of Ecuador to film the birds at 1000 frames per second. As it turns out, different species of manakin use entirely different motion to produce the sounds. The Journal of Experimental Biology has published the results
, complete with videos
. Mark Barres
, who studies avian genetic population structures at the Univ. of Wisconsin, has also filmed the mating dance of the Manakins [.mov]

First Birds with teeth in 70 million years
. Vicious toothed, flying microraptors once darkened the Jurassic skies. Now, scientists
have learned to activate the dormant, vestigal avian "tooth gene" and so coaxed chicken embryos into growing teeth. From the grave, Alfred Hitchcock enviously quips - "a messy thing indeed when toothed birds kill a man". Meanwhile the French are appalled: “quand les poules auront des dents”, which translates to “when hens have teeth”, is analogous to the English “pigs might fly”. Coming soon: flying pigs.
But there might be a baldness cure in this new research. I'll remember that as the flocks of mutant raptor-fowl move in for the kill.
