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

Brookstone filed for bankruptcy and will close its remaining 101 mall stores.The mall and airport seller, best known for massage chairs, quirky gadgets, and travel luggage, filed for Chapter 11 bankruptcy in federal court on Thursday. It was Brookstone's second bankruptcy filing in four years.The company will keep its 35 airport stores and website open and running while it attempts to find a buyer. It has secured a million loan to finance operations during the sale.Brookstone's CEO said in a statement that its airport and online businesses were successful, but an "extremely challenging retail environment at malls" forced the company to close its stores there.Unabated traffic losses at malls have plagued brick-and-mortar sellers. Mall vacancies reached a six-year high last quarter as a wave of stores closed, including Walgreens, Bon-Ton, Sears and Kmart, Best Buy, Kay and Jared, Matress Firm, and GNC."They're trapped in hundreds of these B and C malls, whose traffic has been in serial decline," said Mark Cohen, the director of retail studies at Columbia Business School. "Where they are in triple-A malls, they're faced with very high rent."In 2014, Brookstone filed for bankruptcy and was sold to a Chinese consortium for 6 million. At the time, Brookstone operated 240 stores.The company, which started in 1965 with a classified ad in Popular Mechanics magazine, struggled to implement a digital strategy as shoppers found more places online to buy speakers, headphones, and tech tools they used to only be able to find at Brookstone."The category is Amazon bait," Cohen said. "They lost the thread of newness, innovation and excitement."Steven Schwartz, Brookstone's former chief merchandising officer and interim CEO, called Brookstone's decline "heartbreaking" in a phone interview last week."We were an amazing store company, but we didn't have our eyes on the ball the right way digitally." 1927
