The birdhouse or birdfeeder attracts birds. The birds sing and make other sounds. The microphone picks up the sounds and songs of the birds and transmits them to a receiver. The birdsongs can then be heard through one or more speakers attached to the receiver, thereby, allowing one to view and hear the birds simultaneously. | |
