The cack cack cack and the craw craw craw of the monochrome magpie and the rainbow jackdaw. With an act of ungentlemanly birdfare, they awaken the wood pigeon to a torrid nightmare. But are they really such deadly sinners? As we scare them from the feeder, they just want their dinners. The cack cack cack and the craw craw craw of the monochrome magpie and the rainbow jackdaw.

The cack cack cack and the craw craw craw of the monochrome magpie and the rainbow jackdaw.
