New App Makes Identifying Bird Species Easy

Last October, I was petsitting for a friend and, while out for a walk with the pup, came across a strange looking bird (above). It was sitting, shell shocked, on the hood of a car in Brooklyn. When it was still there an hour later, I decided I would take it and release it in a nearby park—but how do you rescue a bird if you don't even know what kind it is?

No one on Twitter or Instagram could help; a friend who is a birder guessed that it might be a woodcock. So, after reading how to best rescue those birds, I gently wrapped the bird in a towel, slipped it into a paper bag, and walked it down to Brooklyn Bridge Park, where I let it out in some vegetation. It ran away from me, flying in short bursts, as fast as it could.

If only I'd had Birdsnap. This electronic field guide, created by computer scientists at Columbia University and the University of Maryland, can identify 500 common North American birds with nothing but a cell phone photo. The process is simple: Take a photo or choose one from your phone's album; click on the eye and the tail; and wait for the potential matches to show up.

After I'd set the bird loose in the park, my birder friend texted again: another birder believed the bird was a juvenile Virginia Rail, a freshwater marsh bird that mostly keeps to itself. Birdsnap identified the bird correctly on the first try. (How it got on the hood of a car in Brooklyn will forever remain a mystery.)

Columbia Computer Science Professor Peter Belhumeur and University of Maryland Computer Science Professor David Jacobs came up with the idea for the app when they realized that the software and techniques they'd developed for facial recognition could also be used to identify species. Facial recognition algorithms work by finding the resemblance between comparable parts of faces, comparing a nose to other noses and an eye to other eyes, according to Columbia's Engineering Department. In Birdsnap, each species has 17 parts marked; the app detects the parts of the bird so it can compare them with what's in its database and discover species that are visually similar to the animal in an uploaded photo.

"What's really exciting about Birdsnap is that not only does it do well at identifying species, but it can also identify which parts of the bird the algorithm uses to identify each species," said Thomas Berg, a Columbia Engineering computer science PhD candidate. "Birdsnap then automatically annotates images of the bird to show these distinctive parts—birders call them 'field marks'—so the user can learn what to look for.”

And the app, available for the iPhone, does more than just identify birds: It also provides descriptions of the animals and their calls, shows their family trees and similar species, and includes range and sightings maps.

Fisherman Catches Rare Blue Lobster, Donates It to Science

Live lobsters caught off the New England coast are typically brown, olive-green, or gray—which is why one New Hampshire fisherman was stunned when he snagged a blue one in mid-July.

As The Independent reports, Greg Ward, from Rye, New Hampshire, discovered the unusual lobster while examining his catch near the New Hampshire-Maine border. Ward initially thought the pale crustacean was an albino lobster, which some experts estimate to be a one-in-100-million discovery. However, a closer inspection revealed that the lobster's hard shell was blue and cream.

"This one was not all the way white and not all the way blue," Ward told The Portsmouth Herald. "I've never seen anything like it."

While not as rare as an albino lobster, blue lobsters are still a famously elusive catch: It's said that the odds of their occurrence are an estimated one in two million, although nobody knows the exact numbers.

Instead of eating the blue lobster, Ward decided to donate it to the Seacoast Science Center in Rye. There, it will be studied and displayed in a lobster tank with other unusually colored critters, including a second blue lobster, a bright orange lobster, and a calico-spotted lobster.

Australian Scientists Discover First New Species of Sunfish in 125 Years

Scientists have pinpointed a whole new species of the largest bony fish in the world, the massive sunfish, as we learned from Smithsonian magazine. It's the first new species of sunfish proposed in more than 125 years.

As the researchers report in the Zoological Journal of the Linnean Society, the genetic differences between the newly named hoodwinker sunfish (Mola tecta) and its other sunfish brethren was confirmed by data on 27 different samples of the species collected over the course of three years. Since sunfish are so massive—the biggest can weigh as much as 5000 pounds—they pose a challenge to preserve and store, even for museums with large research collections. Lead author Marianne Nyegaard of Murdoch University in Australia traveled thousands of miles to find and collected genetic data on sunfish stranded on beaches. At one point, she was asked if she would be bringing her own crane to collect one.

Nyegaard also went back through scientific literature dating back to the 1500s, sorting through descriptions of sea monsters and mermen to see if any of the documentation sounded like observations of the hoodwinker. "We retraced the steps of early naturalists and taxonomists to understand how such a large fish could have evaded discovery all this time," she said in a press statement. "Overall, we felt science had been repeatedly tricked by this cheeky species, which is why we named it the 'hoodwinker.'"

Japanese researchers first detected genetic differences between previously known sunfish and a new, unknown species 10 years ago, and this confirms the existence of a whole different type from species like the Mola mola or Mola ramsayi.

Mola tecta looks a little different from other sunfish, with a more slender body. As it grows, it doesn't develop the protruding snout or bumps that other sunfish exhibit. Similarly to the others, though, it can reach a length of 8 feet or more. 

Based on the stomach contents of some of the specimens studied, the hoodwinker likely feeds on salps, a jellyfish-like creature that it probably chomps on (yes, sunfish have teeth) during deep dives. The species has been found near New Zealand, Australia, South Africa, and southern Chile.
