Next week searchers with telephoto lenses in-hand plan to commence a 10-day survey of the Cache River Refuge by helicopter in the ongoing search for the Ivory-billed Woodpecker in Arkansas, hoping to scour ~100,000 acres:

There's always been some debate over whether such overflights increase the likelihood of spooking an IBWO out into the open for catching on film, or only cause them to cower more tightly in the safety of the tree canopy... but, there would seem to be little to lose at this point in the effort. Back in 1958, wildlife biologist Herb Stoddard reported sighting an Ivory-bill during a flyover (small plane) of the Altamaha River Basin in Georgia.
Addendum: For the sake of completeness, someone informs me that the helicopter search will include the White River NWR and Wattensaw SWA in addition to the Cache River NWR. Good to know.
