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

Beginning Tuesday, anyone traveling to Hawaii must fill out a "Safe Travels" application, the Hawaiian government announced.In a news release, the government said the health information the travelers provide on the application would be a way for them to protect the health of their residents and visitors during the coronavirus pandemic.The new screening process will also include temperature checks upon arrival and secondary screening for anyone with symptoms or temperatures of 100.4℉ or higher."I am pleased to launch this digital app, which will allow our travelers to provide their required health and travel information before they arrive at the airport," said Gov. David Ige in the press release. "It will also help us keep in contact with those who are required to be in quarantine. This is an important step in preparing to reopen our economy."Currently, the government has visitors fill out two different forms: one for inter-island and trans-pacific travel."This [new] platform provides a one-stop-shop for both types of travelers," the government said.The way it works is that travelers will enter their information and travel plans 24 hours before their flight. They'll then receive a QR code via email, which they will scan at the airport upon arrival.Gov. Ige announced in early August that Hawaii would remain closed to tourists until at least October 1. 1379
