  1. With Oskar Aszmann and his team at the Department of Plastic, Reconstructive and Aesthetic Surgery, MedUni Vienna has long been regarded as a world leader in bionic limb reconstruction. It was only last year that the world's first fully integrated bionic arm prosthesis was developed at MedUni Vienna. This is ready-to-use and is described as "Plug and Play." Although all bionic aids have so far been used in humans, the technique known as osseointegration (direct skeletal attachment) has now been used for the very first time in a bearded vulture—the creature was given a new foot. A paper on this ground-breaking procedure has been published in Scientific Reports.

  2. A team of researchers from Oklahoma State University, the University of Central Oklahoma and the University of Arkansas has found that the mere sight of sick birds of their own kind is enough to set off an immune response in healthy canaries. In their paper published in the journal Biology Letters, the group describes experiments they conducted with caged birds in their lab.

  3. Every night during the spring and fall migration seasons, thousands of birds are killed when they crash into illuminated windows, disoriented by the light. But a new study in PNAS shows that darkening just half of a building's windows can make a big difference for birds. Using decades' worth of data and birds collected by Field Museum scientists at Chicago's McCormick Place convention center, the researchers found that on nights when half the windows were darkened, there were 11 times fewer bird collisions during spring migration and 6 times fewer collisions during fall migration than when all the windows were lit.

  4. The North American mockingbird is famous for its ability to imitate the song of other birds. But it doesn't just mimic its kindred species, it actually composes its own songs based on other birds' melodies. An interdisciplinary research team has now worked out how exactly the mockingbird constructs its imitations. The scientists determined that the birds follow similar musical rules as those found in human music, from Beethoven to Kendrick Lamar.

  5. A recent study by a team of researchers led by Dr. Vinod Kumar Saranathan from the Division of Science at Yale-NUS College has discovered a complex, three-dimensional crystal called the single gyroid within feathers of the blue-winged leafbird. Dr. Saranathan and his team's breakthrough came from their investigation of the feather colors of leafbirds, an enigmatic group of perching birds endemic to South and Southeast Asia (including Singapore), one species of which has evolved the unique crystals in its plumage.

  6. Siberian jays are group living birds within the corvid family that employ a wide repertoire of calls to warn each other of predators. Sporadically, however, birds use one of these calls to trick their neighboring conspecifics and gain access to their food. Researchers from the universities of Konstanz (Germany), Wageningen (Netherlands), and Zurich (Switzerland) have now examined how Siberian jays avoid being deceived by their neighbors. The study, published in the journal Science Advances, shows that these birds have great trust in the warning calls from members of their own group, but mainly ignore such calls from conspecifics of neighboring territories. Thus, the birds use social information to differentiate between trustworthy and presumably false warning calls. Similar mechanisms could have played a role in the formation of human language diversity and especially in the formation of dialects.

  7. A trio of researchers from Manchester Metropolitan University and the University of Edinburgh has found that people filling garden feeders have a pervasive and long-distance impact on bird populations. In their paper published in the journal Proceedings of the Royal Society B, Jack Shutt, Urmi Trivedi and James Nicholls describe their study of bird droppings across parts of Scotland.
