GREY SQUATAROLLE.

This bird inhabits the gravelly borders of lakes 

 and humid fields of the temperate regions of Eu- 

 rope : it is most abundant in France and Switzer- 

 land, and rare in Germany, Holland, and England; 

 being found in the latter country only in the 

 summer, as it breeds within the Arctic circle ; 

 which is the cause of the variety called the Swiss 

 Sandpiper not occuring in these parts. It feeds on 

 worms, and associates in small flocks of six or 

 seven. In the roof of the mouth of this bird is 

 a double row of spinous appendages, pointing 

 inwards.
