This is the audio player that entices nature’s most accomplished vocalists to visit a feeder, perch, or birdhouse. Designed in consultation with ornithologists, the device attracts birds using calls recorded in the field, not digitally synthesized, for maximum realism. Each song represents a number of individuals and plays at naturally occurring sound levels and intervals to give birds the impression others of their species are nearby. One setting plays the melodious songs of bluebirds, orioles, wrens, finches, and indigo buntings, while the other reproduces the song of beneficial purple martins. The attractor can be activated by its internal light sensor to play intermittently from dawn to dusk (four hours continuously for purple martins), or can play constantly. With volume control. Weather-resistant green plastic cabinet. Plugs into AC. 6 3/4" H x 5 1/2" W x 3 1/2" D. (3 lb.)
