If you enjoy birdwatching, this little device is a must. Named in honor of the National Audubon Society by its inventor, it is ingenious in its simplicity. Twisting the birch barrel around the metal plug produces a variety of sounds that will pique the curiosity of most birds; by varying the speed and direction of rotation, you can create a fair imitation of birdsong.
Measuring just over 2 1/2" long, it’s easy to tuck into a pocket before a walk, or you can attach a lanyard or key ring (not included) to the head. If you keep it dry and occasionally add a bit of resin (a vial of powdered resin is included), it will last for several years.
