A curious species of
bird, loosely related to woodpeckers, that produces a wolf-whisle-like call when it locates cheesy-smelling fungi in trees. The species' anatomy is unlike any other
bird, as its body is attached upside-down to its legs, in comparison with other birds. As such, it is able to
peck with much more efficiency than other woodpeckers, using itself like a pendulum to burrow with force into the
tree. The species is found exclusively in northerly areas of the Brazilian Amazon, and is extremely rare.
In modern
slang, to be referred to as a Brazilian Cheese Whistle is to be related to the
bird's extremely unusual stance. It can be somewhat similar to 'idiot', and could be alternatively explained as 'deformed moronic fool'.
