GRALLATORES.— THE WADERS* 



None of the Waders winter in the fur-countries. They arrive generally between 

 the third week of April and middle of May, and depart again early in September, 

 part lingering, however, on the flat shores of Hudson's Bay till the middle of 

 October, when the progress of winter drives the last of them to a milder climate.

This bird breeds on the coast of Hudson's Bay as low as the fifty-fifth parallel. 

 Mr. Hutchins informs us that it makes its nest in the marshes, rudely of grass, 

 and lays four dusky-coloured eggs, spotted with black, — incubation commencing 

 in the middle of June. It feeds chiefly on marine insects.

* For the reason assigned in p. 328, Mr. Swainson has been unable to continue his remarks on the natural groups ; 

 and it being desirable that no attempt at a natural arrangement should be offered, unless it has been tried, as in the 

 preceding sheets, by the test of strict analysis, we have given the Grallatores in the order in which they occur in 

 Temminck's Manual, as being one of the most generally received of the artificial systems. — R.
