A baby monitor, placed on or near my feeder broadcasts the bird chirps and chips into my kitchen. Most battery-powered baby monitors are made up of two separate elements: a monitor unit with a microphone in it that picks up the sounds of baby (or bird) and a receiver that broadcasts the sounds through a speaker simultaneously.

Baby monitors are not terrifically expensive. I found a used one at a yard sale, and thus did not feel at all guilty about leaving it outside in the cold and snow.
