Owls are popular for their late-night hootenannies, yet they aren't the only ones murmuring by moonlight. Environments all over the world host an amazing assortment of night birds — from songbirds and mockingbirds to corncrakes, potoos, and whip-poor-wills — whose voices can be as tormenting (or invigorating) as any owl hoot.br Their after-dim arias are staples in nature's sunset to-day break soundtrack. They are seldom seen but frequently heard, which makes those with huge and various collections hard to recognize.br Peruse on about these birds and their delightful if-shocking tunes so that whenever you're beguiled by a secret performer, you may very well know the craftsman.
