Abstract: Materials and methods for making and using a bird call device involving a surface having a central axis perpendicular to the surface and an opening that is displaced from the central axis by a distance, with the opening being shaped to emit a bird call when the surface is rotated about the central axis.

Abstract: A device for exercising strengthening and toning the musculature of the face comprises a head enclosure with a central portion covering a user's face from the top of the skull to under the chin and jaw line, and from ear to ear; an aperture surrounding a user's eyes and mouth; a series of straps extending from the central portion around the upper and lower sides of the user's head and connecting at the back of the user's head; a top strap extending over the user's head and connecting at the back of the user's head, and a removable neck strap, which can be attached to the sides of the device and extends either around the front of the device under the jaw line, or behind the device around the back of the neck.
