Other Names.—Dabchick; Hell-Diver; Dipper; Dipper-Duck (erroneous).

Description.—Sexes similar. Adults in summer: Glossy, dark brown above; throat black; neck, breast, and sides grayish, washed with brownish and indistinctly mottled with blackish; lower breast and belly glossy white; black band across bill. Immature birds and adults in winter: Similar, but without black on throat and bill. Length: 13½ inches.

Range in Pennsylvania.—Rare as a summer resident, chiefly because 12there are so few lakes and marshes suited to its nesting; fairly common as a migrant from April 1 to May 15 and from August 25 to October 30.

Nest.—Flat, composed of decaying vegetation, floating among water-weeds or anchored by plants which are attached to the bottom. Eggs: 4 to 7, dull white, usually so heavily stained as to be brownish in appearance.
