areas, while others are as widely distributed. It is to the latter 
category that the Grebes or members of this family pertain ; for my 
experience tends to prove that one or other of the numerous species 
are found throughout the entire globe; even in the islands of the 
South Pacific they are to be met with, and also all over North and 
South America. They do not appear to be limited by elevation, but 
tenant the lowest waters and the highest lakes, one of the finest 
being an inhabitant of the celebrated Lake of Titicaca in Peru. 
Grebes are characterized by a peculiarity of structure which enables 
them to chase the nimble fishes and other aquatic creatures under 
water in a different manner from other birds. They construct 
their floating nests on the lakes; and the eggs are frequently in- 
cubated in the water. Although divided into many genera, those 
inhabiting Britain have been retained in the genus Podiceps.
