Broad-winged Hawks are small stocky hawks of the buteo genus commonly found throughout Northeastern and North central North America. Their backs are brown and they have chestnut barring on the chest and abdomen. They have a notable black and white striped tail visible during flight. They produce a high pitched whistle call which is an easy identifier, as they are more secretive during nesting season. Though they can be spotted in the thousands during migration. These huge flocks are called kettles.
