Being home more during the pandemic, and with less traffic on the roads from stay-at-home orders, many people have heard more bird calls and the sounds of nature in urban areas. Scientists now say at least one bird species has been able to adjust their bird song because of the lack of human noise to compete with.Researchers have been studying the white-crowned sparrows in and around San Francisco for more than two decades. They compare their songs in recent years with recordings made in the 1970s.They found as traffic levels increased over the decades, the lowest frequencies of the sparrows’ song rose. This allowed their song to be heard above the low hum of vehicles. The top frequencies remained the same, so the total frequency bandwidth of their communication was narrowed.Degrading their songs this way, and limiting their range, makes them less effective at deterring rivals, attracting mates, or hearing their own chicks, according to researchers. In noisy environments, birds have to sing louder, which research has shown can result in stress and can speed up a bird’s aging and disrupt their metabolisms.When stay-at-home orders and coronavirus pandemic safety measures were put in place in March, the lead researcher, Elizabeth Derryberry, remembers seeing an image of the Golden Gate Bridge in San Francisco completely empty of cars or humans. She wondered how the sparrows were responding.They compared audio recordings of the bird songs from spring 2015 and 2016, to those taken this spring. The recordings were made in a variety of urban and rural locations around the greater San Francisco area.“We found that birds sung at lower minimum frequencies, achieving greater bandwidth songs in newly open acoustic space. An increase in frequency bandwidth results in the transmission of more information and greater vocal performance,” the study states.The samples taken in 2020 revealed the white-crowned sparrows had changed their tune, so-to-speak, and were singing softer and using a wider range of frequencies. They also were able to communicate twice as far as previous recordings.“This doubling in communication distance could elevate fitness by reducing territorial conflicts and increasing mating potential,” researchers stated.Researchers also say this explains why more people report hearing birds during the pandemic. Since the songs are traveling farther distances, humans are able to hear more of them.They also say the changes in the birds’ songs were more pronounced in urban areas compared to the rural location samples. This would make sense, they say, because the traffic noise did not change as drastically in the rural locations during the pandemic.“Our findings indicate that songbirds like white-crowned sparrows have a striking capacity to exploit newly empty soundscapes following acute but ephemeral amelioration of noise pollution, suggesting that lasting remediation might engender even more promising outcomes, such as demographic recovery and higher species diversity in urban areas,” they concluded. 3055

British officials have authorized a COVID-19 vaccine for emergency use, greenlighting the world’s first shot against the virus that’s backed by rigorous science and taking a major step toward eventually ending the pandemic. The go-ahead Wednesday for the vaccine developed by American drugmaker Pfizer and Germany’s BioNTech comes as the virus surges again in the United States and Europe, putting pressure on hospitals and morgues in some places and forcing new rounds of restrictions that have devastated economies. The Medicines and Healthcare Products Regulatory Agency recommended the vaccine could be used after it reviewed the results of clinical trials that showed the vaccine was 95% effective overall — and that it also offered significant protection for older people.“Help is on its way,″ British Health Secretary Matt Hancock told the BBC. “We now have a vaccine. We’re the first country in the world to have one formally clinically authorized but, between now and then, we’ve got to hold on, we’ve got to hold our resolve.”Hancock later added that the country expects to receive the first shipment of 800,000 doses “within days″ and will begin distributing shots soon afterward.According to The Associated Press, England will first distribute the vaccine to people over the age of 80, people in long-term care facilities and health care workers. Government officials believe the vaccine will be widely available sometime in the spring.Pfizer and BioNTech have shattered records in developing their vaccine. The fastest a vaccine had previously been developed came in 1967 when the mumps vaccine was developed in four years. Pfizer and BioNTech have only been working on their COVID-19 vaccine candidate since the start of the pandemic. 1757

BOX ELDER COUNTY, Utah -- The Utah community is mourning the loss of one of its own, a U.S. Air Force pilot from the state who died during a routine training mission off the northern coast of England.1st Lt. Kenneth “Kage” Allen grew up in Box Elder County, but recently moved overseas where he was serving with the 48th Fighter Wing based in the U.K.He had been there for a little over three months when his plane crashed during the training mission.“We are deeply saddened by the loss of our airman and mourn with his family and his fellow reapers in the 493rd Fighter Squadron,” said Col. Will Marshall, Commander of the 48th Fighter Wing.Marshall said Allen was the assistant chief of weapons and tactics for the 493rd Fighter Squadron.On Monday morning, Allen was flying a F-15C Eagle at about 9:40 a.m. when the aircraft crashed into the North Sea.“The outpouring of love and respect from our communities has been a ray of light in this time of darkness,” said Marshall.Allen's death comes just one day after his 27th birthday, and just one week after he recorded himself singing “Time in a Bottle” for his new bride.“Oh my sweetheart Kage,” wrote Hannah Allen on Facebook. “I think I could fill an ocean with the tears I’ve cried today.”The couple were married on Feb. 20, right before Allen joined the 48th Fighter Wing.Family members wrote on Facebook that Lt. Allen was waiting for his wife to join him in England once COVID-19 restrictions allowed.“I never knew a heart could shatter like this,” Hannah wrote. “But I’ve promised you today that the rest of my life will be a tribute to you.”In a tweet, Gov. Gary Herbert paid tribute to Lt. Allen, saying: “He was a Utahn dedicated to making a difference in the world, and kept his virtue through both triumph and disaster.” 1792

Bode Miller, America's most decorated alpine skier, has announced his retirement from the sport.The 40-year-old last raced in 2015 at the World Championships in Beaver Creek, and though he said at the beginning of this year he would consider competing in skiing's FIS World Cup again, he announced Tuesday his career is over. 333
