Waltham animal control officers are looking to find the owner of a lost pet bird that flew into a Waltham police officer’s open cruiser window Monday and landed on his shoulder. “We haven’t found the correct owner, but a lot of people have asked about it,” said animal control officer Deanna Gualtieri. The bird, a sun conure, is currently in a foster home, but animal control is hoping that the owner will come forward. Conures resemble parakeets, and people often call them that. Anyone with information is asked to call the Waltham Animal Control Division at 781-314-3596.
