short answer : hearing
long answer (found on Petplace.com) To a rabbit hearing is a vital sense, hence the large upright ears. The auditory system is used to detect predators, as well as to help a rabbit perceive the area around him. Acoustics help to overcome the reduced visual abilities by allowing the rabbit to navigate without difficulty. Sound waves bounce off objects, allowing the rabbit to recognize the arrangement of his surroundings. Most rabbits have large, erect ears. When alert, the ears move forward and backward as they attempt to pinpoint the danger. When the rabbit is relaxed, the ears lie along his back, but they are quite responsive to noise. The slightest sound can be detected from very far away. A rabbit's sense of sound is vastly developed, far more finely tuned than his vision.

Rabbits have long external ears. Frogs do not have external ears. Or, maybe they have some kind of hole at most. Take a look at some pictures of frogs.
