Peregrine Falcon Released After Rehabilitation
December 17, 2019
Milly — a Peregrine Falcon who was found at Spittal Pond — has been released after receiving rehabilitation and care at the Bermuda Aquarium, Museum and Zoo.
While our animal care staff have extensive experience with seabirds and small perching birds, raptors are rare accessions into our rehabilitation program and they normally arrive in such bad shape that they seldom survive.

“They require careful handling in captivity due to their ability to seriously injure a caregiver with either a talon or hooked beak designed for tearing up small animals. After initial examinations it was found to be a young female that was extremely underweight. 2 weeks of intensive care by our dedicated staff brought her back up to the weight of an average adult.
The day before her release she was fitted with a GPS-GSM Solar-Powered Telemetry unit from Cellular Tracking Technologies, purchased by the Atlantic Conservation Partnership, the US based support charity for BAMZ.

“These ‘tags’ are new technology that utilise GSM cellular networks to pinpoint location and other data which is then transmitted for cloud-based accessibility online. The tag has a solar panel and must be small enough to not impede the bird in any way, but large enough to allow for the panel and the hardware needed for the data collection and transmission.

:1val: 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. :flirty: 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!"

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.

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!

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.”

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. ”

Totally NOT related to bird cams but in this time of a global pandemic I thought this was worth sharing. Translated with Google.
Original page, with some external links

Have we completely misunderstood COVID-19 so far? As the list of recognized symptoms grows, it seems that the different syndromes of the virus can be divided into six clusters. We may be missing the main signs of the disease in children.

These insights can help researchers answer the question of how the virus can affect different people and how an outbreak in a kindergarten can look very different from an outbreak in a care home.

More than a respiratory infection
When the world first became aware of a new coronavirus floating around in the Chinese city of Wuhan in January, cough, fever and respiratory problems were the main symptoms of the disease caused by the virus, according to health organizations. If the infection was serious, someone could develop pneumonia. The condition didn't seem to differ much from other respiratory infections.

Over time, this picture changed. Currently, the World Health Organization and health organizations in the United States are naming a wide variety of COVID-19 symptoms.

"We're learning more and more about the symptoms," said Angela Rasmussen of the Columbia University Mailman School of Public Health. 'In the beginning we focused on symptoms related to breathing, because it would be a respiratory disease. But we have since discovered that it is much more complex. '

Risk factors
One of the first discoveries was that the virus causes more severe symptoms in older people, as well as people with underlying health problems. But the effect varies greatly from person to person - many young people have also died from it. "We realized that it can vary enormously from person to person," said Carole Sudre of King's College London.

It is not clear what exactly determines how sick someone becomes, but there are plenty of factors that could play a role. "All these people come from somewhere else, have different eating habits, different genes and a different medical background and access to healthcare," says Rasmussen. "All these things create a unique environment for the virus to reproduce, and each body responds differently."

The exact way of exposure to the virus can also have an effect, Rasmussen says. For example, subtly different virus variants could cause a different immune response. And the number of virus particles a person is exposed to could influence what symptoms they develop. The route of the infection - via nose, eyes or mouth - can also play a role.

Six clusters
Researchers have now tried to gain insight into the various manifestations of the virus with the help of the so-called Covid Symptom Study app , developed by the start-up ZOE. More than 4.4 million people from the United Kingdom, the United States and Sweden have signed up since its launch in late March. App users must enter their age, location and health information. Then they should report how they feel every day. You can also enter the results of any corona tests in the app.

Based on a sample of 1,653 app users , the researchers identified six clusters of symptoms (see "Six types of COVID-19," at the bottom of this post).

Three of the clusters are relatively mild. People who fall into the other, more severe clusters often experience fatigue, chest pain, and confusion. People in cluster six generally get very sick.

"If a person only suffers from the upper respiratory tract, the risk of going to hospital and needing ventilation is much lower than in other cases," said Claire Steves of King's College London, co-author of the study. 'When a person develops symptoms all over the body - not just nose and throat, but also muscles, chest, stomach and brain - the chance that someone will have to go to the hospital greatly increases.'

Whether or not to test
Sudre, who is also part of the research team, hopes that looking at a person's symptoms in this way will help health professionals estimate how much help someone needs.

In addition, the results of the study could help in decisions about who should or should not have a corona test. For example, the RIVM currently advises that only people who suffer from a cold, cough, chest tightness, elevation or fever and loss of smell or taste should be tested. Because of the variation in the symptoms - and the many people who don't develop them at all - you could miss corona cases this way.

Researchers are also trying to find out how symptoms develop over time. The symptoms used by the RIVM and many other health organizations usually appear between two and fourteen days after infection. "At that time, someone could have already infected others," says Sudre. Her colleagues are now investigating which symptoms are most likely to show themselves first. Right now, it seems that headaches and fatigue strike first - symptoms that we sometimes may ignore for a while at first.

Diarrhea and vomiting
COVID-19 appears to have a different effect on children. If we want to recognize the disease in them, we may need to look at other symptoms. Especially in young children, an infection appears to be very different than in adults.

That's what Tom Waterfield of Queen's University Belfast and his colleagues discovered when they examined the symptoms of 992 children treated for various conditions in the UK. 68 of them had the coronavirus among the members. Waterfield's team compared their symptoms to those of the children who didn't have the virus.

"The children showed many different symptoms, with a lot of overlap," says Waterfield. Using a computer model, the team examined which symptoms best predicted whether a child had COVID-19 and not another common infection. Although many of the children had a fever and had to cough, these symptoms were often the result of other viruses. "If you want symptoms that allow you to identify as many corona cases as possible with as few tests as possible, then you should take diarrhea and vomiting," he says.

The testing strategy currently in use in the United Kingdom would have missed 24 percent of symptomatic corona cases in the children studied, the team found. But if you consider diarrhea and vomiting to test, you will detect 97 percent of the cases.

ACE2 receptors
There seems to be a difference in symptoms not only between children and adults, but also between children of different ages. For example, teenagers are much more likely to report changes in their taste and smell than young children - although this may also be because young children are simply less able to highlight this complaint.

This is in line with other research that suggests that the way the virus spreads to teens is more like the way it spreads to adults. Where this difference comes from is still unclear.

"Perhaps differences in the immune system of young and old have something to do with it," says Peter Brodin of the Karolinska Institute, a Swedish medical university. Some researchers believe that the ACE2 receptors that the virus binds to play a role in this. Children have fewer of these receptors in their nose and throat.

This could also mean that the coronavirus is spreading differently among young children. The prevailing thought is that the virus moves through the air in large droplets and small aerosols. But if you look at the rate of diarrhea and vomiting in young children, poor bathroom hygiene can also play a role in the spread, Waterfield says.

Another common symptom among the children in Waterfield's study was fatigue. He now fears that many of them will continue to suffer from this after recovery from the initial infection. This is already a trend among adults. Some people say they still have symptoms of 'long-lasting COVID-19' weeks or even months after the first symptoms.

Six types of COVID-19
A research team from the Covid Symptom Study classified the symptoms occurring with COVID-19 into six types:

Flu-like symptoms, no fever
Headache, loss of smell, cough and sore throat, but no fever. About 1.5 percent of this group eventually requires artificial respiration in the hospital.
Flu-like symptoms, but fever
Comparable to group number 1, plus loss of appetite and fever.
Gastrointestinal complaints
Diarrhea accompanied by loss of smell and appetite, headache, sore throat and chest pain. Usually no cough.
This cluster is more serious than the previous three, as 8.6 percent of the people in this group eventually require ventilation. Fatigue is accompanied by a headache, loss of smell, cough, chest pain and fever.
Another serious category. People experience confusion in combination with the symptoms of group 4. Around 10 percent require artificial respiration.
Belly and Respiratory System
The most serious cluster, as half of the people in this category need to be hospitalized and a fifth on a ventilator. Symptoms include headache, fever, loss of smell and appetite, cough, sore throat and chest pain, along with shortness of breath, diarrhea, abdominal pain, muscle pain, confusion and fatigue.

A very contagious bird flu (H5N8) is killing hundreds of birds. Birds of prey also fall victim to this disease because the eat the dead ones or catch the weakened ones. In the area where I live (Wadden Sea) there are now 6 confirmed dead Peregrine Falcons and people are very concerned about the White Tail Eagles here as well (they too eat carrion)
