Pied-billed Grebe 9 
Description.—Adult—Crown and back of the neck greyish-black, 
becoming a paler grey on the sides of the head and front of the neck ; 
a black oval patch on, the chin and throat ; rest of the upper-parts and 
wings dark fuscous-brown; u little white on theinner webs of the 
secondaries ; below silvery white, but obscured on the sides and across 
the breast by dusky and buffy mottlings ; iris brown and white, bill 
yellowish, bluish-white in life, encircled by a broad black band, legs 
blackish. Length 13:0; wing 55; culmen -90; tarsus 1-75. 
In winter the bill is dull yellowish and has no black band ; the throat- 
patch is absent and there are more or less distinct pale edges to the 
feathers of the upper-parts. Young birds are like the adults in winter, 
but the throat and sides of the head have indistinct brownish streaks. 
Distribution—Nearly the whole of America, from Saskatchewan 
to Patagonia, breeding throughout most of its range; wintering from 
about New Jersey and the southern United States southwards. 
This Grebe does not appear to be a common bird in Colorado ; 
generally it is a summer resident but is more abundant on migration. 
The first breeding record is that of W. G. Smith who found several 
nests at Loveland, but it probably also breeds at San Luis Lakes as 
there is a specimen in the Aiken collection from that place, taken on 
July lst. It reaches Loveland in spring in the latter half of April, 
and was seen by Carter on migration at Breckenridge (Cooke). Warren 
informs me he has noticed it on a small lake near Crested Butte at 
9,000 feet in October. It is included by Henderson in the Boulder co. 
list, and is a common breeder at Barr in May and June (Hersey & 
Rockwell), the letter of whom has recently published some notes and 
photographs of its nesting habits. I have not heard of it in the south- 
west or western part of the State, though it probably occurs there. 
Habits.—This, the most familiar of the Grebes in the 
East, is often known as the Water-witch, Hell-diver 
or Divedapper ; it does not materially differ from the 
other Grebes in its habits, nor has anything special been 
noticed about its occurrence in Colorado. Nests found 
by Smith in a lake close to Loveland contained six eggs 
as a rule and were, when first laid, a pale pea-green colour, 
but soon became stained by the wet weeds with which 
they were covered. A clutch of six eggs taken by 
I. C. Hall at Storm’s Lake near Greeley on May 25th, 
1902, and presented by him to the Colorado College
