Birds Avoid phantom road noise:-
Biologists have known that bird populations decline near roads.The birds avoiding traffic or the noises produced by them?Noise might be a big factor, reasoned because scientists have seen declines in bird populations near noisy natural gas compressor sites.
Researchers,created a “phantom road” at a site in the Boise Foothills that is a stopover(short stay between journey) for migratory birds in the fall and put up 15 speakers in Douglas fir trees then played recorded sounds of a road.
After this they counted birds at three locations where the road sounds heard and three locations where the sounds could not be heard.When the noise was Played, “fewer birds were present there.” The cedar waxwing and yellow warbler completely avoided it.
The only Cassin’s finch, was seen near the noisy place.Noisy areas can be bad because noise interfere with bird communication, So birds avoid noisy areas.
