"In the past, people thought birds were stupid," laments the aptly named scientist Christopher Bird. But in fact, some of our feathered friends are far cleverer than we might think. And one group in particular -- the corvids -- has astonished scientists with extraordinary feats of memory, an ability to employ complex social reasoning…

Zebra finches, which normally learn their complex courtship songs from their fathers, spontaneously developed the same songs all on their own after only a few generations. "We found that in this case, the culture was pretty much encoded in the genome," said Partha Mitra of Cold Spring Harbor Laboratory in New York, co-author of the…

After last week's look at an emu dissection, it seemed only logical to follow up with dissection pics of another ratite. So when John Hutchinson of the Royal Veterinary College (RVC) mentioned his dissection photos of Ozbert the ostrich, I asked politely, and received. Note that all photos are © John Hutchinson and Jason Moore, and are used with permission. Ozbert's suspended cadaver is shown here [note the gigantic calf muscles and extruded phallus].
Ozbert, donated by a British ostrich farm, was huge, tipping the scales (when plucked) at 129 kg (the world record is supposedly 160 kg) […

Here is a mystery I'd really like to know the answer to. On the way to school this morning, Will discovered a dead baby bird. Here it is: the photo (which I took on my phone) is atrocious, so there's little point in showing it at larger size. Clearly, this is an altricial, nidicolous passerine chick, probably of a Blackbird Turdus merula. The question is: how does an altricial nestling like this - barely able to walk in its own nest, least of all out of it - get to be dead in the middle of the pavement? No, it didn't fall out of its nest, because there were no overhanging trees or bushes…

Inspired by comments made following the emu dissection article from Monday, I got thinking about elongate tracheae in birds. As we'll see, this subject is fertile ground if you like serious weirdness and spectacular extremes [Trumpet manucodes shown here, from wikipedia.. all will become clear]. Before we get to that serious weirdness and those spectacular extremes, a bit of basic anatomy...
The trachea - or windpipe - is, as I'm sure you already know given that you've got one, a tube that extends along the ventral surface of the neck from the larynx to the lungs [singular: trachea, plural:…

In these images, the yellows indicate lower activity…
