This is a computer program that plays bird sounds. A rare bird might sing every day for a long period of time, but it is not likely. The probability that a blackbird or a chaffinch will sing during night time is small, but it might happen. Some days the jackdaw will sing together with the nightingale, other days with the magpie, or on its own, in solitude. Start the program and wait for the birds to start singing.
