Thread: What is it that makes the high pitched ringing/screaming noise in the trees in

Marmaris, Turkey? On holiday recently in Turkey we kept hearing this shrill noise from the trees all day. We initially thought it may be crickets perhaps, but they'd have to have been thousands of them! I was wondering if it was the trees themselves?

As a matter of fact there ARE thousands of crickets in Marmaris forests. We are a little nature-ignorant, are we?
