These are approx. 8 min long cartoons in a half hour format. Two Birdman cartoons bracketed a Galaxy Trio cartoon. This series originally aired on NBC. It premiered September 9, 1967. It was a Hanna-Barbera Production. Birdman is a superhero with wings on his back and gets his strength from the sun, which he is continually having to recharge. He uses the sun energy in the form of heat rays and force beams and can produce a sheild made of solar energy. His sidekick is a giant eagle named Avenger, and they sometimes work for the U.S. government under the direction of a covert operative named Falcon 7. Birdman's one downfall is his habit of shouting his name constantly.
