Hundreds of birds, Chiang Mai, Thailand
Hundreds of birds singing on overhead power lines, recorded by Marcel Gnauk.
"I am not sure how many birds but at least a few hundreds are sitting on the powerlines and chirping extremely loudly. I remember a few months ago recording sounds of a few thousand herons in Bali but this one is a little bit different.
"I couldn’t avoid the street noise because its right next to four site intersections.
"I came back on the next morning to get some photos of the place but the birds are all gone. What you can see is a ton of poop on the ground, on the wires and on my helmet!"
