Escaped peacock freezes to tree in Chicago as temperatures drop to -24C Not a proud moment... A peacock froze to a tree branch in the Chicago area as temperatures plummeted to -24C. AN ADVENTUROUS peacock had to be rescued by Chicago-area firefighters after he flew from his heated pen to a nearby tree and froze to a branch in polar-like temperatures. The Daily Herald reports that Blue the peacock is recovering after Tuesday's misadventure that lasted about 90 minutes. Blue managed to fly from his enclosure at the Randall Oaks Barnyard Zoo in Dundee and perched atop a nearby pine. Firefighters with a ladder helped zoo staff pluck the wayward bird from the tree. The temperature at the time was about -24C. Brian Mangiaracina is Randall Oaks' park and division manager. He says the whole thing was a "freakish accident" and that Blue is in quarantine. Dundee is about northwest of Chicago.
