Word Origin and History for stool pigeon
n.

"police informer," 1868, American English; earlier "one who betrays the unwary (or is used to betray them)," 1821, originally a decoy bird (1812); said to be from decoys being fastened to stools to lure other pigeons. But perhaps related to stall "decoy bird" (c.1500), especially "a pigeon used to entice a hawk into the net" (see stall (n.2)). Also cf. pigeon.

Idioms and Phrases with stool pigeon

stool pigeon

A decoy or informer, especially a police spy. For example, Watch out for Doug; I'm sure he's a stool pigeon for the supervisor. This term alludes to a bird tied to a stool or similar perch in order to attract other birds, which will then be shot. However, one writer believes that stool is a variant for stale or stall, both nouns used for a decoy bird before 1500 or so. [ c. 1820 ]
