Abstract: Disclosed is a bird deterrent device to prevent pest birds from landing and nesting in various outdoor areas. The bird deterrent device of the present invention includes an elongated stem with a pointed lower end that is adapted to be inserted into various penetrable surfaces such as soil or ground. The stem further includes a plurality of spike members disposed near the top end thereof, wherein the spike members branch outward from various locations around the elongated stem and extend outward therefrom at various angles. The spike members may also overlap one another to prevent birds from roosting on the bird deterrent device. When the device is positioned, the spike members span out in a fan-like arrangement to eliminate open areas within its immediate perimeter. In this way, the present invention prevents birds from landing and resting in specific areas without harming the pest birds.
