JOB POSTING: SECURITY GUARD PREFERRED CANDIDATE: BLUE JAY The glaucous raucous blue jay is ever alert. Even the soft pads of the bobcat's feet fail to escape its detection. This sagacious sentinel IDs potential danger, the bobcat preparing to crouch, and blows its cover. Intruder right here, the blue jay's repeated calls alert other avians in an APB. Now the blue jay has backup. The bobcat gets off with a stern lecture and a warning.
