This is the most common Grebe in New England, where 

 it is a summer resident. It undoubtedly breeds in all these 

 States, as it is frequently taken in the breeding season ; but 

 its nest, owing to the secluded habits of the bird, is very 

 rarely found. It is described as being similar to that of the 

 preceding species. The eggs, five in number, are covered 

 with a calcareous deposit, which gives them a dirty yellow- 

 ish-white color : on scraping this off, the shell beneath has 

 a bluish-white tint. The form of the egg is exactly ovoidal. 

 Specimens in my collection, from Illinois, measure about 



2.17 inches in length by 1.45 inch in their greatest breadth. 

 Another, from Wisconsin, is only 1.95 inch in length, and 



1.18 inch at its greatest breadth.
