Article from the LA Times about the Big Bear Eagles. I love the "bonding" picture they selected! The hottest 24/7 reality show in Southern California right now could be called “The Real Bald Eagles of Big Bear Lake.” |

Saw a reference to this on a chat and thought it was interesting. To think this eagle was shot at one time (not what this article is about, but found when examined) and now has collided with the windshield of a semi traveling down the road and has survived is amazing!! Info shared by chatter (who photographs this eagle), but not in article is: the bullet is in the shoulder that they will leave be, hoping to be released on Tuesday, photographers from site shared photos with rehab to ID her, eggs normally in February, Dad (her mate) has been looking and calling for her. I am hoping this female eagle is able to be released as above and reunites with her mate. From ABC news: Friday, January 24, 2020 3:23PM NEW HAVEN, Connecticut (WABC) -- A bald eagle and truck driver avoided a near fatal accident Wednesday when the bird collided with the 18-wheeler on a busy highway in Connecticut, according to police officials. The female bird was scavenging food along northbound on I-95 near Exit 44 in New Haven when she spotted roadkill and swooped down from a lamppost onto the center lane, officers say, resulting in the blaring horn of an oncoming car that scared her off. Police say as she flew up to avoid being hit, the bald eagle collided full force with the windshield of the 18-wheeler, shattering it completely. Scott Burke, the unharmed truck driver, stated that it happened so fast and was one of the scariest things he has encountered in all his 25 years of being a truck driver. Burke immediately called police after the accident. Authorities say the eagle hung on to the side of the truck cab until a complete stop was made about 1,000 feet later. In order to avoid any additional collisions, police decided to close down the highway to safely rescue the eagle. The eagle was rushed off to A Place Called Home, a wildlife rehab center in Connecticut, where it was determined she had no fractures, but did have blood inside of her mouth and trachea. It was also revealed that the bird was shot in the past. The adult eagle will be released once the rehab center sees her bleeding has subsided. |

Not actually in the news, but newsworthy from MN DNR eagles: "Countdown to the hatch The rare glimpses we get of our eagles’ eggs may suggest not much is going on with them, but inside those white shells a host of physiological changes are or will soon be unfolding in what amounts to a 72-hour countdown to the hatch. One of the main things that needs to happen is for the embryonic chick to switch from getting oxygen through the membrane that surrounds it in the egg to breathing on its own. First, a muscle at the nape of the chick’s neck swells and causes the head and beak to twitch and press against an inner membrane that eventually is pierced, allowing air to reach the chick. At this point it starts to actually breathe, and the chick’s parents may be able to hear faint chirping from inside the egg. As the chick breathes and re-breathes the air inside the egg, carbon dioxide accumulates, causing more muscle spasms. A bony protuberance on the chick’s beak known as the “egg tooth” taps at the shell until a tiny, barely visible star forms, letting in some fresh air. With that, the chick usually calms down for a few hours before creating a larger, visible hole known as a “pip.” EagleCam watchers may recall seeing the pip, with a tiny beak visible inside, in years past. With an opening to the outside, the chick’s lungs become fully functional, which triggers the little bird to start rotating inside its shell, industriously cutting around the egg’s circumference until a cap is loosened and the bird first lifts its fluffy head into view. The week or so after hatching tends to be one of the riskiest for chicks. These three eggs were laid on February 6, 9 and 12, and incubation usually lasts about 35 days, so we’re all keeping our fingers crossed and hoping for a successful hatch soon!" |

From Poppy the mod at Hog Island, Chesapeake Ospreys: Poppy Mod • 5 hours ago • edited You might experience a lesser quality in YouTube videos and live streams, this is why: (CNN)Videos on YouTube will now default to standard definition for all users worldwide, a step down from the typical high definition that users normally see. The move is aimed at easing the burden on internet infrastructure as lockdowns and other emergency policies have kept millions at home. The global change, which was announced and began rolling out on Tuesday, is expected to last for approximately 30 days as millions of people around the globe stay home amid the coronavirus pandemic. In a statement, YouTube said the move is meant "to do our part to minimize stress on the system during this unprecedented situation." Users will still be able to manually change to a higher resolution on a per-video basis, YouTube told CNN. YouTube and Netflix previously said they would reduce streaming quality in Europe for a limited time to prevent the internet collapsing under the strain of unprecedented usage due to the coronavirus pandemic. Due to more people working and studying from home, the internet's underlying infrastructure is expected to face "an enormous stress test," industry analysts have told CNN. Even some of the biggest tech platforms are now grappling with a greater challenge in keeping their services up and running amid surging demand. Last week, Facebook (FB) CEO Mark Zuckerberg told reporters that the company's platforms are facing "big surges" in engagement, with traffic patterns exceeding what the company ordinarily sees around the New Year's holiday. On Tuesday, Adam Mosseri, head of Instagram, said there is "a lot of usage, a lot of demand" on the service. During an Instagram livestream, Mosseri added that a new feature on Instagram dedicated to showing what users are doing from home — titled Stay Home — was so popular it "almost took down Instagram" in its opening hours. |

Ran across this a few minutes ago on FB and thought some here might be interested: Wildlife Center of Virginia 1 hr · We admitted another Bald Eagle over the weekend -- this banded female eagle was hit by a vehicle on Sunday. Band results confirmed that she is a four-year-old female, who is actually the offspring of Bald Eagle "ND" - a bird who hatched at Norfolk Botanical Garden in 2010. That means this eagle is Buddy the Bald Eagle's niece! |

Dutch Eagle Fan wrote: Article, in Dutch so you need Google to translate it, about a bar-tailed godwit (Limosa lapponica) that migrated from Alaska to New Zealand, setting a new world record! English translation! WOW! Thanks DEF! Bar-tailed godwit pulverizes world record flying nearly thirteen thousand kilometers across the Pacific Two quarreling bar-tailed godwits The record "non-stop long-range bird flying" has been set by a bar-tailed godwit, nearly eight thousand miles across the Pacific Ocean. How do they do that?! Rob Buiter10 oktober 2020, 21:04 The new record holder has the poetic name "4BBRW", after the colors blue, blue, red and white, from the rings on its legs. It is a male of the bar-tailed godwit that was caught in New Zealand almost a year ago and fitted with a transmitter. On September 16, he left Alaska for a trip southwest. On September 27, he had the more than ten-year-old record of non-stop flying of its fellow "E7" of 11,600 km. And when he arrived in a bay east of Auckland, New Zealand, he broke that record: 12,854 km! The flight of these and other extreme migratory birds can be followed on the website of the Global Flyway Network, a collaboration of migratory bird researchers led by Groningen professor Theunis Piersma. “What these birds do is really unimaginable,” he says, calling from the car he uses to follow Dutch spoonbills on their trek to Africa. Refuel on the coast Piersma: “Those bar-tailed godwits first fly from their breeding grounds on the tundra of Alaska a few hundred kilometers to the tidal flats on the coast. There they eat completely full of shellfish and seaweed. At one point, they consist of almost half fat. A bar-tailed godwit with an empty tank weighs nearly three ounces, but on departure from Alaska, they weigh more than a pound! Where they normally can just fly straight up, they have to take a run up to get loose, just like a swan on the water, that's how heavy they are when they leave. By the time they arrive in New Zealand, the tank is really empty; then they are half as heavy again. ” In order to be able to carry such a large amount of fuel, birds save on the size of their organs during migration. Piersma: “That seems to be controlled by an internal clock. With another long-distance hiker, the knot, we see that around the pull time they almost automatically get bigger muscles, and organs like stomach and liver get smaller. That is true even if we keep them in a cage, where they cannot fly great distances to train their muscles. That greasing is also well established. Even if we change the day-night rhythm of the birds with the help of lighting in the cage, the birds still prepare for the migration by eating extra.” The flight record of the bar-tailed godwit. Image Global Flyway Network Economical with fuel The enormous distances that birds can travel non-stop continue to amaze scientists time and again. In 1950, American bird researchers wrote in scientific literature that a mere thousand kilometers across the Gulf of Mexico must be an impregnable barrier for a bird. Research with ringed birds in the years after showed that even three thousand miles was a feasible hurdle. In 2008, the bar was set more than twice as high. Bar-tailed godwits from Alaska that received a transmitter in their belly were found to be able to fly 11,000 km across the Pacific Ocean in eight days. Now it appears that we can go one step further: 12,854. A major key to this bizarre achievement is the modest amount of energy the birds appear to need to move forward. Swedish biologists calculated a few years ago that a bar-tailed godwit uses only 0.42 percent of its body weight in fat to fly nearly 60 kilometers per hour for an hour. That is the lowest fuel consumption of all the flying animals they examined. A hummingbird, for example, consumes nearly five times as much - up to 2 percent of its body weight in "fuel" to fly for an hour. Several godwits The bar-tailed godwits that fly from Alaska to New Zealand are of a different subspecies than the bar-tailed godwits that occur in our Wadden Sea in spring and autumn. They fly from their breeding grounds in the tundra of Siberia to the wintering grounds in West Africa. Especially in the spring, on their way to the breeding area, these birds use the Wadden Sea as a filling station. “Then they eat mudflats here,” says Theunis Piersma. "Our Wadden Sea is an essential gas station to complete that hike." The red-haired "tundra groat" is somewhat related to our national bird, the "meadow groat". “We have also been giving those birds miniscule transmitters for several years now, with which we can follow them on their migration,” says Piersma. “In this way, all these" world godwits "teach us not only about the migration, but also, I think, about the state of the world. For example, from the changing migration of bar-tailed godwits to Siberia, we can clearly see how the tundra there is warming much faster than any part of the world. And the black-tailed godwits clearly show in their migration and distribution the effects of our intensive agriculture on the landscape. ” Mysterious navigation To fly from Alaska to New Zealand across the vast Pacific Ocean, you need at least a good compass and a map. It seems that the bar-tailed godwits leaving Alaska also have a good weather map in their pocket, Piersma says. “If you look at the routes of the different birds on the map, you see that they are certainly not taking the shortest route, and sometimes also make big turns. We can only understand these routes if we project the high and low pressure areas with the corresponding wind directions on the map. Then the birds appear to make perfect use of favorable wind directions. ” But tailwind or not, if you are flying over an endless ocean, without visible landmarks, then you have to somehow know where you are and which direction to take? “That orientation and navigation remains a mystery,” Piersma must admit. “If the birds only had a compass needle in their head or in their eyes, they wouldn't make it. They must also have some sort of GPS to know where they are at any given time. They probably make some use of the earth's magnetic field, which differs from place to place, but also of the polarization of the sunlight and the stars. ” And then sleep An empty tank after more than 10,000 kilometers of flying is one thing. Bird researchers in New Zealand now know that bar-tailed godwits need to make up more shortages. Piersma: “During the first few days these birds sleep a lot more than their peers who have been on the spot for some time. Even if the food appears on the mud flats at low tide, they just continue to sleep. It seems that after an extreme hike, lack of sleep is an even higher price than lack of fuel. ” Also read: Why do birds migrate from Africa to the Arctic? Migratory birds nesting in the far north are less likely to suffer from predators stealing their eggs, it seems. Is that why they go to all that trouble to fly thousands of kilometers back and forth every six months? https://www.trouw.nl/nieuws/waarom-trek ... ~ba0dcffd/ |
