...bird-lime:

"A glutinous substance extracted from the inner bark of the holly, and used for catching birds. The bark is bruised, boiled with water till very soft, and then placed in pits to ferment."

-- T. Ellwood Zell's _Popular Encyclopedia_, 1871

Sign me, Dan what do we do with them once we've caught them Becker
