GREY ^kOi'lkXh—iMotacilla suMurea; formerly, 

 M. boarula). 



Less plentiful than the Pied Wagtail, equally ele- 

 gant and more beautiful, this little bird resembles the 

 other in its ways and habits. Its nest is placed on 

 the ground at no great distance from water, which has

 "Nanny Washtail." The materials and general 

 structure are, in the main, the same as in the last case; 

 feathers and wool beincr introduced as a lininor. There 

 are often five or six eggs in it, of a faint white ground- 

 colour, mottled and streaked with very light brown, a 

 few streaks being sometimes of a darker tint. — Fig. 20,

Ray's Wagtail, Cow-bird. — A summer visitor, and,

 ground, in corntields or fallows ; sometimes on a stump 

 of a tree level with the ground, or on a bank of earth 

 overhanging water, or in a hole in a wall in the same 

 vicinity. The said nest is made of moss, roots, dry 

 grass, and lined with the same, only finer, and a little 

 hair. Four to six eggs are laid, which, Mr. Yarrell 

 says, "are not unlike those of the Sedge Warbler,
