These loudcheeps and peeps might give the location of the nest away to a listening hawk or raccoon, resulting in the death of the　defenseless nestlings. In fact, when tapes of begging tree swallows were played at an artificial swallow nest containing　an egg, the egg in that “noisy” nest was taken or destroyed by predators before the egg in a nearby quiet nest in 29 of　37 trials.(Begging by Nestlings)
