        Twinter and often hunts well before dark in summer if it has
        a family to feed.At such times, it allows excellent views, frequently
        at roadsides where verges may provide almost the only remaining
        rough grassland over which it can hunt for voles. It also frequents
        marshy areas such as rough grassland beside reedbeds or along
        embankments.There is little chance of misidentification, although
