No need to page through guidebooks looking for the mystery bird you just spotted — all you need is an iPhone and the new Birdsnap app, or a digital camera and computer. Snap a picture in the app or upload an image to the Birdsnap website, click on the bird’s eye and tail, then enter the location and date where the bird was found. Sophisticated algorithms detect parts of the bird, such as the beak and the belly, then maps the bird according to “a common coordinate system from which [Birdsnap] can extract features for the identification system,” explains one of Birdsnap’s creators, computer scientist Peter Belhumeur of Columbia University. This is similar to how facial recognition systems map features such as the nose and eyebrows to identify people, even when they’re not facing a camera head-on.

Tracking Cuckoos to Africa... and back again. Project Noah. Conservationists and marksmen of Malta battle over annual bird hunt. As dawn breaks over the sea and ancient stone churches turn pink, the morning's stillness is broken by volleys of gunfire.
Tucked behind walls, sitting on armchairs in specially built turrets or else popping up from old stone sheds, Malta's marksmen open fire as migrating birds flap desperately for cover. When it comes to bird hunts, this is one of Europe's more uneven contests. Birds flying over the islands of Malta on their annual migration to northern Europe must evade 31 licensed marksmen per square kilometre – 15 times more than in shooting-friendly France.

Although it’s easy to assume that cats purr because they’re content, research shows that purring is likely a means of communication and a form of self-healing.
Yes, your feline friend purrs when you stroke her fur, but cats also purr when they’re frightened or feel threatened, such as during a visit to the veterinarian. Veterinarian Kelly Morgan equates this reaction with smiling. “People will smile when they’re nervous, when they want something, and when they’re happy, so perhaps the purr can also be an appeasing gesture,” Morgan told WebMD. A cat’s purr begins in its brain. A repetitive neural oscillator sends messages to the laryngeal muscles, causing them to twitch at a rate of 25 to 150 vibrations per second.
