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

Big league players will still hear the roar of the crowd even though the stands will be empty when the baseball season opens next week.Taking a cue from two European soccer leagues, Major League Baseball will play crowd noise from its official video game through ballpark sound systems during games. Stadium sound engineers will have access to around 75 different effects and reactions, according to MLB, which has provided teams with crowd sounds captured from “MLB The Show.”San Diego Studios, a branch of Sony Interactive Entertainment, compiled the noise during games over several seasons.Clubs started using the sounds during summer camp games and will be able to test them further during exhibition games.“There was some reticence when you first talk about crowd noise in an empty ballpark because you don’t want to do something that is distracting,” said Chris Marinak, who is MLB’s Executive Vice President for strategy, technology, and innovation. “It is heard in a way that is natural with the play of the game and on field. The sounds do match what is happening.”England’s Premier League and Spain’s La Liga were the first to return to action with crowd sound from video games. The leagues enlisted EA Sports to provide crowd effects they engineered for the FIFA video game franchise. Marinak said MLB talked to multiple companies before deciding to go with Sony.Baseball is hoping the crowd noises, along with stadium announcers, walkup music and in-stadium video, will replicate the in-game experience as closely as possible without real fans in the stadium. Some ballparks are also offering fans the chance to buy photo cutouts which will be placed in the stands.Brewers infielder Eric Sogard said Thursday that the crowd noise did help step up the competition for some guys during intrasquad games.“You’re still focused on the game but that noise is very helpful. I could tell the first few scrimmages with pure silence was tough for some guys,” he said. “You could hear the other dugout talking and it was kind of awkward.”The sounds will also be audible on radio and television. The Korean baseball league pipes in crowd noise at stadiums so they are not completely silent but it is barely audible during games aired on ESPN.Some fans and broadcasters are leery of artificial crowd noise because it takes away a unique opportunity to hear players’ conversations during games this season. Alex Rodriguez noted during an ESPN conference call that the only time fans can hear that type of interaction is if they go to spring training workouts.ESPN announcer Matt Vasgersian is hopeful there still might be some sort of audio sweet spot to provide a little bit of everything.“I think it still allows us to capture some of that and still make the viewing experience feel right at home,” he said. “I can’t wait to hear what we hear. Nobody involved in broadcasting baseball wants to compromise strategy. We’re not looking to pry into the playbook but we do want to hear things that maybe we wouldn’t hear ordinarily.”The NBA has been in contact with 2K Sports about possibly using its sound library when the league resumes play outside Orlando, Florida.___AP Sports Writer Steve Megargee in Milwaukee contributed to this report.___More AP MLB: https://apnews.com/MLB and https://twitter.com/AP_Sports 3319

Brunch can be a big draw for many restaurants, including at Sam’s No. 3 Diner in Denver, where the wait time to be seated on weekends could take up to two hours.“It gets crowded on that sidewalk out there,” said owner Sam Armatas.Pre-pandemic, Armatas says the iconic downtown diner had more than 180 seats. Now, with new health restrictions, that number has been cut to 83.“Business has been affected greatly,” Armatas said. “It’s a different world, it’s a different way to operate, and it’s a different way to serve.”Less seating means less opportunities to make money which led management at Sam’s to look outside their restaurant to serve more customers.“I kind of just looked over at my neighbor and thought, ‘hey, they’re not using that patio during the day. Maybe I can use that patio during the day,’” Armatas said. “So, I got in contact with Matt.”Matt Ruff is the general manager and part owner of Dazzle, one of the top 100 jazz clubs in the world.“It’s kind of foolish not to lend our neighbors a hand during this time,” Ruff said.Ruff is lending Dazzle’s outdoor patio space to Sam’s during the day for free, a move customers seem to appreciate while industry experts are calling it a financial Band-Aid.According to the National Restaurant Association, somewhere between 15,000 to 20,000 restaurants across the country closed their doors for good during this pandemic.Experts expect that number to increase nationwide as an estimated 8,000,000 American service industry workers are already out of jobs.“We’re monthly doing the revenue we would do on a good Saturday,” Ruff said. “How do you survive with doing something like that?”So far, this partnership with Dazzle and Sam’s sharing space seems to be working out well for both businesses.“It’s been awesome,” Armatas said. ”It’s an additional 12 to 15 seats that we didn’t have before.”The plan is to continue sharing this space until these establishments are able to operate at full capacity or the weather no longer allows for outdoor seating. 2020

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

Before last week, membership in the National Rifle Association meant gaining access to a broad range of discounts. From special rates on auto insurance policies to cheaper flights when you booked through its website, the NRA's discount program offered a lot of perks.But in the wake of a massacre at a Florida high school on February 14, activists flooded social media with calls to end corporate partnerships with America's most powerful gun lobby.Since Thursday, more than a dozen brands severed ties with the organization.In a statement, the National Rifle Association called the decisions "a shameful display of political and civic cowardice.""In time, these brands will be replaced by others who recognize that patriotism and determined commitment to Constitutional freedoms are characteristics of a marketplace they very much want to serve," the statement said.NRA members still have access to other perks, such as a free gun-owner insurance plan and options to save on travel costs.But the listings on the organization's "Member Benefits" page have dwindled.Here's how it all went down.Thursday, February 22The First National Bank of Omaha said it will stop issuing an NRA-branded Visa card. A bank spokesperson said "customer feedback" prompted a review of its partnership with the NRA, and it chose not to renew its current contract.Enterprise Rent-A-Car, Alamo Rent a Car and National Car Rental, which are all owned by Enterprise Holdings, announced the brands would stop offering NRA membership discounts on March 26.Friday, February 23Symantec, which makes the Norton anti-virus software and owns the identity theft protection company LifeLock, announced it "has stopped its discount program" with the NRA.Hertz made its announcement in a tweet. "We have notified the NRA that we are ending the NRA's rental car discount program with Hertz," the company said.MetLife said it will stop offering NRA member discounts for home and auto insurance policies.SimpliSafe, which makes home security systems, "discontinued our existing relationship with the NRA," CEO Chad Laurans said in a statement.Related: Bank of America wants to talk to its customers who make guns Avis and Budget Rent a Car, which are owned by Avis Budget Group, said through a spokesperson that the brands will stop offering discounts on car rentals to NRA members beginning March 26.Allied and North American, two moving-van lines that are both owned by Sirva, said that the brands "no longer have an affiliate relationship with the NRA effective immediately."TrueCar, a car buying service, said late Friday that it would end its deal with the NRA as of February 28.Saturday, February 24Delta Air Lines announced Saturday morning that it's ending discounted rates for NRA members. "We will be requesting that the NRA remove our information from their website," the company said in a tweet.United Airlines followed a short time later, saying the company will no longer offer discounts on flights to the NRA annual meeting.Paramount RX works with a third-party vendor to provide a prescription drug discount program to NRA members, but the company said in a tweet Saturday that it is "working with that vendor to discontinue the program and remove the offering."Starkey, a company that makes hearing aids, announced Saturday evening that it has decided "not to renew our discount program with the NRA" and asked the organization to "remove our information from their website."  3467
