50 yards to 200 or more

Duration of observation:

30 minutes

Habitat: 

Open lake of a fairly shallow lake.

Behavior of bird: 

Upon our approach they craned their heads in a sign of alarm, I observed the long black and white necks. and long bill, then they dived and separated.  They could stay under water a long time and would come up 100 yards away.  I think they heard the motor and swam under the water away from the sound.  I did not see them resting, except on our initial approach, when they sat on the water with a slight bend in the neck. We chased them for less than an hour just familiarizing ourselves with a new species of bird.

Description:

They were black and white, with a longish dull yellow bill.  neck long white front and black rear, black back, gray in part of the wing barely visible, very agile at diving and swimming under water.  These are birds about twice the size of Eared and Horned Grebes, although slimmer in overall impression. 

Voice:

Not heard.

Similar species:

The Red-necked Grebe is noticeably smaller and chunkier and darker over all.  It does not have a black and white neck.  Horned Grebe in winter has a similar black and white neck, but it is much shorter and a much smaller bird.  I don't see how any bird but the Clark's Grebe could compare, and the Clark’s did not exist in a nomenclaturally sense, at that time.
