Birdlime

Bird-lime, a sticky, viscid substance, used by bird-catchers. The bird-lime is spread on twigs, and around a cage containing a decoy bird. The birds, attracted by the singing of the decoy, alight on the prepared twigs, from which they are unable to extricate themselves. It may be prepared by bruising holly bark, boiling with water, and allowing to stand for some weeks; or from flour, by immersing in water in a calico bag, and squeezing out the starch; also by boiling linseed oil until the desired consistency is obtained.
