Future Oliver! costar Ron Moody adds most of the spice to this above-average fifth-season Avengers episode. Moody plays Jordan, one of several people involved in a plot to smuggle military secrets to the Enemy by way of a parrot named Captain Crusoe. In the course of the Avengers' investigation, Emma once again finds herself in one of those perilous situations which require her to begrudgingly accept Steed's gallant assistance (on the other hand, she does get to show off her high-diving skills). Scripted by Brian Clemens from a story by Alan Pattillo, "The Bird Who Knew Too Much" was first seen in England on February 11, 1967, and in America on March 10 of that same year (after being rescheduled from its original February 10 playdate).
