Abstract: Apparatus and method for detecting when an animal is in heat is provided. The apparatus includes a logic controller, a power source, a clock, an actuator, and a presentation interface such as an array of LEDs (Light-Emitting Diodes) that records breeding behavior in animals and presents corresponding data in a manner that can readily be observed from a distance. The method includes, according to some embodiments, receiving a first stimulus, validating that the first stimulus was received incident to a first mating-behavior event, receiving a second stimulus incident to a second mating-behavior event; and storing the occurrence of the first stimulus along with a time indicator for future retrieval and display on a presentation interface, wherein the presentation interface includes an LED array.
