Bird-repelling drone imitates a real-life predator to clear property of unwelcome pests

Scarecrows and other visually intimidating props placed on the ground can be useful in deterring birds within a certain radius, but one company is looking further afield by battling the pests in the sky. Designed to resemble a real-life bird of prey, the ProHawk UAV can be programmed to autonomously fly over a property and emit menacing predatory cries as it goes.

Bird-inspired self-folding wings could help drones recover from collisions

If you've ever watched a flying bird weaving its way through a forest, you may have wondered how it could do so without hitting its wings on the trees. Well, birds actually do hit trees with their wings. Unlike the rigid wings of an aircraft, however, birds' wings simply fold back under impact, then immediately fold open again to maintain flight. Now, scientists from Stanford University have developed wings for flapping-wing drones that do the same thing. Read More

Bird-inspired system could result in smoother flights

Turbulence can be unpleasant enough for passengers in full-sized aircraft, but it's even more of a challenge for unmanned micro air vehicles (MAVs) – a good gust can blow one of the little drones completely off course, or even cause it to crash. That's why a team from RMIT University in Melbourne, Australia, has looked to birds for a solution. The result is a system that detects turbulence before it buffets the MAV, allowing the aircraft to anticipate it and thus maintain a smoother flight. The technology could also be applicable to regular airplanes. Read More

Robotic raptors look and fly like the real thing

Birds that stray into the paths of aircraft, eat crops, or spread disease from foraging in large numbers at landfills are, at best, a nuisance and, at worst, downright dangerous. Over the years people have tried everything from scaring them away with loud noises to trapping them – all with varying results. Now a designer from the Netherlands has come up with robotic birds of prey that look and fly exactly like the real thing. Read More

Shape-changing wings inspire more efficient aircraft designs

We tend to think of aeronautical engineering as having left the birds standing still sometime around the First World War, but since jet fighters can’t perch and quadcopters can’t snag salmon out of a stream, we still have a few things to learn. Taking a couple of pages from the avian playbook, Fraunhofer Institute for Electronic Nano Systems (ENAS) and its partners are developing wing flaps for airplanes that change shape like a bird’s wing for greater efficiency.

Review: Snapzoom binocular adapter for smartphone cameras

Chances are that you already carry a smartphone with you wherever you go, and if you're a wildlife-watcher, hiker, or sporting-event spectator, then you likely also have a pair of binoculars. Well, the Snapzoom is a new product that brings those two devices together – it lets you get telephoto snapshots of distant subjects, by holding your phone's camera lens in alignment with one lens of your binoculars. I recently got a chance to try the thing out for myself, and liked what it had to offer. Read More

Toxin-detection system inspired by turkeys

Turkeys may not be everyone's idea of beautiful birds, but they certainly have colorful skin on their heads. What's more, that skin changes color with the animal's mood. Scientists at the University of California, Berkeley, have now copied the process by which those color changes occur, and used it to create a biosensor that could be used to detect airborne toxins.
