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

BEAVER DAM, Wis. (AP) — A Wisconsin apartment building where a fatal explosion took place was deliberately burned by firefighters Thursday.Authorities set fire to the building in Beaver Dam to burn chemicals that could not be removed because of their volatility. Those who lived in the building had not been allowed to return to retrieve any belongings or keepsakes because of the danger of another explosion.About 20 area fire departments with at least 100 firefighters assisted with the controlled burn.28-year-old Benjamin Morrow, who lived in one of the units, was killed in last week's explosion. Police believe he was making bombs when chemicals accidentally detonated. A funeral service for Morrow will be held Thursday in Madison. 751

BRANDON, Fla. -- A Florida woman says someone threw some type of acid on the side of her 2002 Ford Explorer that was parked outside a Kmart in Brandon. Glenda Banfield said she was in the store for about an hour when she came out to find the paint on her car bubbling. "My paint was down to the metal," she said, "I rubbed my hand down over it and it just came off in flakes."Banfield was parked in a disabled parking space in the front row towards the entrance of the store. "I wish I would have just stayed home," said Banfield.Banfield, who lives on disability, is on a fixed-income and took the car in for a repair estimate, "they said it would be at least ,500."  703

BOULDER, Colo. — A Boulder, Colorado man reached out to KMGH, furious about the work done by a contractor hired through the popular online service Thumbtack, and the thousands of dollars he claims he lost. The more he dug into the service, the angrier he became.               Keeping his windows clean is key for Larry Koenigsberg, considering he has amazing views from his home a hilltop community in Boulder."I can see a panoramic of the Flatirons, Pike's Peak when the sun rises in the morning," said Koenigsberg. "It’s like being on vacation every day between Colorado's 300 days of sunshine a year."Using popular online service Thumbtack, he hired Top Window Cleaning and paid the owner to clean several large windows, a skylight and a shower door. It wasn’t until the next day he realized they were damaged."The sun came shining in through all the south-facing windows, and I see all these scratches and I go outside and they're still dirty," said Koenigsberg.KMGH reached out to the owner of the window cleaning service. His attorney said no comment.Koenigsberg said that the owner of the company and the only employee came back to clean them again, hoping it was only dirt."So severe, it looked like a prism with all the blue and orange. Very deep the scratches," said Koenigsberg.After confronting the man, Koenigsberg said he only got another bill, not an apology. He went online to several sites to share his experience."I wanted a way of venting and letting other people know, and I put my review on there, but also I indicated that his intentions were good. I don't think that anybody sets out with intentions to scratch windows," said Koenigsberg.Koenigsberg said he learned Top Window Cleaning is not licensed in Colorado and the owner has a criminal history. He believes it was after he notified Thumbtack of the situation they closed the cleaning service's account. A Thumbtack spokesperson told KMGH: 2026
