112 The Pred Wagtazl, 


where pebbles, both large and small, project above the 
surface. 
When the Pied Wagtail is taking a long flicht, 
either from fright or design, it can be told by the 
curved line it moves in, which resembles a chain hang- 
ing in curves from point to point—each abrupt stop 
being about the distance of three or four yards from 
each other.
