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

BOZEMAN, Mont. — Cloie Musumecci sent MTN News a brief video of a woman tripping and falling as a bison charged at her and another person in Yellowstone National Park.Cloie said in an email that the incident happened at Nez Perce Creek. She said the woman "is a Montana local so she knew to play dead in that situation."The woman was was not injured and escaped "without a scratch," Cloie said. No further information has been released yet, such as whether or not the visitors got too close the bison.We are trying to get more details about the incident and will post an update if we learn more.Park officials says that animals in Yellowstone National Park are wild. When an animal is near a trail, boardwalk, parking lot, or in a developed area, visitors must give it space.Stay 25 yards away from all large animals – bison, elk, bighorn sheep, deer, moose, and coyotes - and at least 100 yards away from bears and wolves.Bison are the largest mammals in North America. Males can weigh up to 2,000 pounds and stand up to six feet tall, according to the Department of Interior.This story originally reported by MTN News on krtv.com.Several recent incidents involving visitors and wildlife at Yellowstone:Woman gored by bison in Yellowstone parkWoman injured by grizzly in Yellowstone parkChild tossed in air by bison in YellowstoneWoman knocked down by bison in Yellowstone park 1386

BASALT, Colo. — Firefighters battling the Lake Christine Fire got a special treat Friday when Neil Diamond stopped by to perform “Sweet Caroline” and other songs for them.Diamond and his wife came by an Incident Command Post to meet and thank the firefighters who have been fighting the blaze, which was estimated at 12,588 acres Sunday evening. The fire is 82 percent contained.In a separate video, he points a finger at the firefighters.“Now, you have to save my house,” he said.Diamond has lived in the area for about 20 years.He said he wanted to thank the firefighters for coming to the area and lifting the heaviness in the community members’ hearts.“We know the cavalry is here,” he said in the video. “We say thank you of each of you.”  Watch the video of the impromptu concert here. 804

Bicycle injury accidents have ticked up in the city of San Diego this year, as the city has seen thousands of dockless bikes appear across its neighborhoods since January.New city data shows that there were 130 injury accidents involving bicyclists through May 1, 2018, up from 102 in the same period of 2017.A San Diego Police spokesman said it would take more research to determine whether the uptick is related to dockless bikes. However, the data shows that some parts of the city are seeing fewer incidents, while others are seeing more. Hillcrest, for instance, has seen improvement. By May 1, 2017, there were already seven injury accidents in the heart of the neighborhood. This year there have not been any.However, there has been an increase on Mission Boulevard along the coast, which has no bike lane and can get narrow. In 2017, there was just one injury accident on the boulevard. Through May 1, that number was up to six. Claire Mathena, who lives in Hillcrest, said she can't afford a car but the dockless bikes help her get around."Everyone's in a hurry, I just don't think people are paying attention. I just don't think it has anything to do with the dockless bikes," she said. Meanwhile, others, like Stephan Vance, choose to commute daily by bike. He rides from Ocean Beach to his job at the San Diego Association of Governments. "Don't do anything you wouldn't do if you were driving driving a car," he said, noting some key tips are to ride with traffic on the ride side of the road, be predictable, and always signal.Thursday is bike to work day, with SANDAG hosting a series of pit stops and events along hundreds of miles of bikeways in the region.  1723
