'The seagull defecation scheme (WW11). Admiral Sir Frederick Inglefield RN succeeded in convincing the Admiralty that seagulls could be trained to locate and defecate on raised periscopes. For months in the back water of one of the less crowded harbors, Admiral Inglefield and his reluctant staff attempted to encourage and train several seagulls to deposit droppings on any of several dummy periscopes floating in the harbor. Developing incontinence in the seagulls proved too much for him, and Admiral Inglefield was quietly placed in a position of less responsibility -- far less responsibility. The seagulls went back to defecating on everything, and the Allied navies began serious ASW planning.' Naval Historian Kit Bonner.
Bubbleheads dont like those buzzy choppers anyways so converting 'em to gulls is a non-starter. Besides gulls 'aint nice - all that pecking on the superstructure drives the matelots mad.
