   Note: The {Lanius excubitor} is the common butcher bird of
         Europe. In England, the bearded tit is sometimes called
         the {lesser butcher bird}. The American species are
         {Lanius borealis}, or {northern butcher bird}, and
         {Lanius Ludovicianus} or {loggerhead shrike}. The name
         butcher bird is derived from its habit of suspending
         its prey impaled upon thorns, after killing it.
