  • Estimates of bird collision mortality at wind facilities in the contiguous United States

    Abstract Wind energy has emerged as a promising alternative to fossil fuels, yet the impacts of wind facilities on wildlife remain unclear. Prior studies estimate between 10,000 and 573,000 fatal bird collisions with U.S. wind turbines annually; however, these studies do not differentiate between turbines with a monopole tower and those with a lattice tower, the former of which now comprise the vast majority of all U.S. wind turbines and the latter of which are largely being de-commissioned. We systematically derived an estimate of bird mortality for U.S. monopole turbines by applying inclusion criteria to compiled studies, identifying correlates of...

    From grasslands to seashores to forests and backyards, birds are disappearing at an alarming rate in the United States and Canada, with a 29% population drop since 1970 and a net loss of about 2.9 billion birds, scientists said on Thursday.
  • Ecologists find bird-deterring nets create haven for stinging venomous caterpillars

    Rice University evolutionary ecologists have discovered huge quantities of one of North America's most venomous caterpillars. Texas Medical Center (TMC)—which is visited by 10 million people seeking health care each year—are routinely netted to discourage pesky birds such as grackles and pigeons. Now Rice researchers have learned the netting has an unintended consequence: Chasing away birds that eat insects has created a haven for a flourishing population of Megalopyge opercularis, commonly referred to as asps. When a human is stung by an asp, it can cause localized pain that is compared to blunt-force trauma or a bone break. Egan's team...
  • Some birds risk their lives for a good nap, scientists find

    But some birds risk their lives by snuggling up to conserve energy. If they sleep with their head tucked in the scapular feathers, they enter a sort of deeper sleep that is associated with lower energy consumption but exposes them to a higher predation risk If they sleep with their head tucked in the scapular feathers, they enter a sort of deeper sleep that is associated with lower energy consumption but exposes them to a higher predation risk. When the birds were presented with the sound of crunching leaves, they were slower to respond than the forward-facing birds.

    A giant cannibalistic parrot that stood more than three feet tall and lived in New Zealand 19 million years ago has been dubbed 'squawkzilla'. Scientists reckon the animal, which is officially known as Heracles inexpectatus, feasted on other parrots to nourish its massive frame. The tree-dwelling creature is believed to have used its enormous beak to feed on the flesh of its own species. It is thought to be the largest parrot ever and rivals the famed dodo in its bulk, and towers above the current flightless inhabitants of New Zealand, the kakapo.

    Stephen Vedder used to enjoy peaceful lakeside runs near his Marlborough, Mass., home. This spring, after years of coexisting with an ornery neighbor, those tranquil outings came to an end. It started with a whack to the back of the head. Next, Mr. Vedder was divebombed. Then clawed. The culprit was a red-winged blackbird. More than 250 million of the birds live across North and Central America, and this summer some are feeling extra aggressive toward human neighbors—driving them to change walking routes, wear protective headgear or furiously wave arms above their heads as they jog. “You talk to people...

    A new publication from the Global Warming Policy Foundation reviews the impact of wind energy on the environment and finds that it is already doing great harm to wildlife. “The Impact of Wind Energy on Wildlife and the Environment” contains contributions from both researchers and campaigners, with a focus on birdlife. Professor Oliver Krüger describes his cutting-edge research, which has shown how birds of prey and ducks are being killed in their thousands in Germany. The risk to these species is so great that there is a possibility of whole populations being wiped out. Klaus Richarz, the former head of...

    Inside a Crimean cave was a gigantic ancient mystery just waiting to be uncovered: a bird so large that it weighed nearly as much as an adult polar bear. Giant birds once roamed Madagascar, New Zealand and Australia. The latest fossil find, an intriguing fossilized femur, was recently found in Taurida Cave on the northern coast of the Black Sea. It was discovered along with other fossils, including bison bones, that helped researchers date the now-extinct giant bird to between 1.5 million and 2 million years ago. When the first early human ancestors arrived in Europe, they might have encountered...

    An “avian incident” sparked a fire at one of California’s biggest solar farms, affecting 1,200 acres and knocking out 84% of the California Valley Solar Ranch’s generating capacity. The June 5 incident didn’t damage solar panels at the 250-megawatt power plant, but distribution poles and cables need to be replaced, according to a regulatory filing Wednesday from owner Clearway Energy Inc. The company didn’t say exactly how the blaze was ignited. “We are pleased that in the aftermath of the fire at California Valley Solar Ranch, our team and first responders were able to ensure the safety of the surrounding...

    Dubbed Ambopteryx longibrachium, the blue jay-sized theropod lived 163 million years ago during the Jurassic period. Its wings were made of a soft membrane attached to long arm bones which, when spread, resembled those of a bat. ..." The researchers first thought it was a bird when they saw it in the rock, but after they dug it out, it became clear that Ambopteryx was a dinosaur. The researchers aren’t sure exactly how the dinosaur, which also had feathers, looked as it took flight. It couldn’t flap its wings, so it’s believed the creatures would simply glide. According to the...
  • If Drones Had 'Claws,' They Might Be Able To Fly For Longer

    Small drones can do big jobs: Firefighters can use them to find hot spots in blazes, environmental monitors can find the source of hazardous chemical leaks. One just delivered a human kidney for transplant surgery. But it takes lots of power to spin four helicopter blades fast enough to keep a quadcopter-type drone in the air. Most can only stay aloft for about 30 minutes. So an international team of roboticists is trying to extend the time a drone can stay on the job. For inspiration, they turned to birds. "Birds usually fly somewhere and they stay at the top...

    A Florida wildlife breeder was killed by one of his birds almost two weeks ago—and now that bird is going up for auction. More than 100 exotic animals from the estate of Marvin Hajos are being sold off after the 75-year-old man was fatally attacked by a 6-foot-tall cassowary at his Alachua County farm. The flightless birds are often called the "world's most dangerous bird" thanks to their "dagger-like" claws that can grow up to 5 inches long. Hajos fell down between two cassowary cages on April 12 and was attacked through the fence by at least one of the...

    Did you hear the one about the owl and a duckling that lived together? It might sound as though it has come straight from the pages of a story book but the bizarre real-life partnership has been captured by a photographer from Florida in their own back yard. Laurie Wolf, from Jupiter, initially thought an eastern screech owl that lived in a nearby tree had chicks of her own, known as owl hatchlings.

    The large, flightless birds, with dagger-like claws, are considered the world’s most dangerous. “He was doing what he loved,” she said, adding that she did not want to talk anymore. "The cassowary can slice open any predator or potential threat with a single swift kick. Powerful legs help the cassowary run up to 31 miles per hour (50 kilometers per hour) through the dense forest underbrush.” “It looks like it was accidental. My understanding is that the gentleman was in the vicinity of the bird and at some point fell. When he fell, he was attacked,”

    PALM BEACH COUNTY, FL (Gray News) - A 35-year-old Florida man lost his life Saturday while trying to retrieve a pigeon he cared for from a power line. Deputies from the Palm Beach County Sheriff's Office found Elian Garcia-Rivera around 3 p.m. They told The Palm Beach Post he used a 20-foot aluminum pool pole to try and move his bird, but accidentally touched the live power line. The shock threw him to the ground between a large pigeon coop and a fence. Paramedics transported him to a local hospital where he passed away. "There are no words to say,"...
