US Patent 7802405 Metal bird spike with memory shape base

A bird deterrent device is presented having a base that is at least partially composed of a metal or metal composite. The base can be configured such that the base has sufficient resiliency to revert to an original form after being bent at least 15°. A plurality of spikes can be coupled to the base so that the device is stackable with other such devices while the spikes are oriented at least 5° out of parallel with respect to a plane of the base. It is contemplated that the devices can be stacked such that the base of one device is less than 3 cm from the base of an adjacent device in the stack.
