"Green woodpecker!" "Make that 12".
In desert areas the smaller owls rely primarily on holes made by woodpeckers in large cacti.
To build their nests, the parrots find holes made by woodpeckers seeking insects in bark.
It is this special design of the tongue that makes the woodpeckers efficient in catching the insects inside trees.
The shape of the barbet's bill, which is not at all chisel-tipped like that of a woodpecker, makes the excavation of cavities in trees a task requiring great effort, and it appears that only dead, well-rotted trees are used.
We take it for granted that the woodpecker makes the sound by striking the surface of a resonating object, but as recently as the 1940s, some people still maintained that the bird made the sounds vocally.
The videos are not directly equivalent because the Pileated Woodpeckers made only short escape flights to nearby trees, whereas the putative Ivory-billed Woodpecker in the Luneau video showed little sign of coming to rest before being lost from view.
More expensive sound systems can be programmed to make the predator sounds when a woodpecker comes close.
All were within the size range of nest holes made by pileated woodpeckers.
