extensile

It has an excessively long, slender muzzle, and a worm-like, extensile tongue.

Three thousand of them, for a single meal, he has been known to lick out of a hill with his long, round, extensile, sticky tongue.

Bill shorter than the head, straight, conical; tongue long and extensile; nostrils without bristles, partly closed by a membrane; wings with the second primary somewhat the longest; tail-feathers soft and flexible.

Most of the caterpillars have oval, slug-shaped, smooth bodies, with the under surface flattened, and very small heads, which in many species can be extended by means of an extensile neck.

The only other North American birds that have a tongue built upon this plan are the hummingbirds, in which also it is extensile.
