extensile

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

It is really astonishing to see what large morsels they can dispose of with the assistance of their extensile mouths and stomachs.

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

They are, however, quite extensile, and can readily be made to hold three or four times this amount.
