These sweet birds sense light, sound, touch and movement and respond with real bird songs and chirps. Placed on the handle of a walker, the bird sings as you move. When you stop, it chirps out a sweet "don't forget me" reminder. Set on a tabletop, it sings when touched, spoken to or senses movement. Perch included. Requires 3 AAA 1.5V batteries (included). Ages 5-105.
