A swamp in Luisiana was livened up by a claim that an ivory-billed woodpecker had been spotted. Thought to be extinct for the last sixty years, birdwatchers flocked to the area, cameras and tape recorders in hand, to catch a glimpse of this holy grail of the ornithological world.
Cornell University set a series of recorders and Zeiss Sports Optics sent a team of scientists, who managed to record the double-tap of this largest American woodpecker (with a wingspan of 72 cm or 30 inches).
However, close analysis of the double-taps on the tape revealed that the noise was caused by shotguns going off, as hunters bagged wild turkeys.
The ivory-billed woodpecker remains elusive.

How many angels are there on the tip of the needle? This question is just as pointless as an attempt to find an answer to the question of how many NATO missiles there are in Europe
