Abstract
Blue jays trained to detect Catocala moths in slides were exposed to two types of slide series containing these moths: series of one species and series of two species intermixed. In one species series, detection ability increased with successive encounters with one prey type. No similar effect occurred in two species series. These results are a direct demonstration of a specific search image.
