Galapagos finches caught in act of becoming new species  A population of finches on the Galapagos has been discovered in the process of becoming a new species. This is the first example of speciation that scientists have been able to observe directly in the field. Researchers followed the entire population of finches on a tiny Galapagos island called Daphne Major, for many years, and so they were able to watch the speciation in progress. http://www.bbc.com/news/science-environment-42103058 |

Bird of prey returning to Denmark in numbers  The population of red kites is taking off in Denmark, with at least 200 breeding pairs of the bird of prey now present in the country’s natural areas. The Danish Ornithological Society (Dansk Ornitologisk Forening, DOF) has estimated that number will as much as double in coming years. A limited number of areas across the country, including south-eastern Jutland, Funen, Bornholm and northern Jutland, are considered the current prime spots for the species. But the growing red kite population is showing signs of spreading to other western and northern habitats, according to ornithologist Per Rasmussen, who has collected data on the animal. https://www.thelocal.dk/20171227/bir...ark-in-numbers |

Hypnotizing video captures thousands of starlings zigzagging as hungry falcon attacks  Starlings are known to flock together into mesmerizing groups called “murmurations,” and then swoop and dive together in synchronized acrobatics shows. But this group of starlings — part of a murmuration of as many as 10,000 that has gathered in West Cork, Ireland — started doing particularly impressive aerial tricks earlier this month. It was caught on video by a group of local birdwatchers, too. http://www.star-telegram.com/news/na...#storylink=cpy |

These tropical hummingbirds make cricket-like sounds other birds can't hear  Researchers have found that a tropical species of hummingbird called a black jacobin makes vocal sounds with an unusually high-frequency pitch that falls outside birds' normal hearing range. It's not yet clear whether the hummingbirds can even hear themselves, the researchers say. https://www.sciencedaily.com/release...0305130659.htm |

10 of the World’s Fastest Birds  From the peregrine falcon to the common swift, meet the cheetahs of the sky. June 30, 2020 The cheetah will almost always win a race on land. But in the sky, the contest for the fastest bird depends on whether you're measuring level flight or speed while diving after prey. Researchers aren't in agreement about which bird gets top honors. In fact, the Guinness Book of World Records was actually created in the 1950s when Sir Hugh Beaver, managing director of the Guinness Brewery, got into an argument with friends about the fastest game bird in Europe. No one could find an answer in a reference book, so Beaver decided to create one. Here are some of the speediest fliers in the skies. https://www.treehugger.com/fastest-birds-5070090 |

The pesticide that caused bee colonies to collapse is killing birds now
Neonicotinoids, thought to be responsible for colony collapse disorder, have detrimental effects on birds, too Aug 18, 2020 Environmentalists and farmers were relieved to discover that the mysterious and sudden drop in bee populations in the past decade turned out to be linked to neonicotinoids, a class of insecticides that are chemically akin to nicotine. Solving that mystery was not merely important to ecologists, but also crucial to human survival: if major bee communities become extinct or near-extinct, it could devastate human food sources. https://www.salon.com/2020/08/18/the...ing-birds-now/ |

Audubon Christmas Bird Count Kicks Off
It's time for citizen scientists to get out their binoculars. Dec 14, 2020 The 121st annual Christmas Bird Count (CBC) from the National Audubon Society begins on Dec. 14. Researchers are depending on tens of thousands of volunteers to grab their binoculars to help gather data about birds throughout the Western Hemisphere. Experienced bird watchers and eager amateurs will be contributing to one of the longest-running wildlife surveys, which runs through Jan. 5. The CBC helps ornithologists study the movement, range, and fluctuation of bird populations across the continent, which enables them to better understand how bird species are faring and changing over time. https://www.treehugger.com/audubon-c...ks-off-5092152 |
