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.
