• Birds stand to benefit the most
• Birds — by far the most visible animals found in cities, and also the most vocal — stand to be among the biggest beneficiaries of quieter streets and parks.
• The signals birds send each other through song is a means of survival. Without the ability to sing, hear and be heard, birds would have a difficult time finding a mate or defending their territory from predatorsLIVE TV

• Coronavirus lockdown gives animals rare break from noise pollution
• 16.04.2020
• The COVID-19 lockdown could become an unprecedented natural experiment in noise pollution. Some of the world's most vocal animals — birds and whales — might already be benefiting from a quieter environment.
• While a drop in transportation during the coronavirus lockdowns has led to lower pollution levels across the world, the slowdown in traffic has also lowered another big polluter: noise.
• According to the World Health Organization (WHO), noise pollution affects over 100 million people across Europe and, in Western Europe alone, road traffic accounts for premature deaths equivalent to the loss of roughly "1.6 million healthy years of life."
• Take the disturbance to human health out of the equation, and noise remains a big source of pollution for the other inhabitants of the planet as well, namely, animals.
• But how much have animals in countries on lockdown really benefited from the drop in noise levels? Turns out, that's a very difficult question to answer.

• There are reports of seeing more birds during the lockdown. Ornithologists say this is due to increased awareness of people's surroundings while at home
• Human activity influences bird behavior, even prompting them to communicate at less 'busy' times of day
• The swift rise of human-made noise — also known as anthropogenic noise — over the past century has made this harder for birds.
• Just like humans who have to speak up in a loud setting, birds, too, have to sing louder to communicate properly in today's noisy world, according to ornithologist Henrik Brumm, who heads the research group for the communication and social behavior of birds at the Max Planck Institute for Ornithology near Munich.

"This happens really fast," Brumm told DW. "We found out that it takes roughly 300 milliseconds, so less than 1 second, for birds to readjust when the level of noise rises. So, when their surroundings become louder, they sing louder, too."
