The E-edhead is a regular, though rare, migrant in New

 the female Whistler for the Red-head ; the former has a 

 dull reddish-brown head, and shows a considerable patch of 

 white on the wing. (See p. 297.)

Many of the diving ducks described in the preceding

 in the interior of New England and in eastern New York. 

 Two of the Mergansers described in the following section also 

 occur as migrants on inland ponds and streams. All these 

 species, however, dive for their food, and may be thus dis- 

 tinguished from the true river or pond ducks, which obtain 

 their food by tipping in shallow water, after the manner of
