CINCINNATI ZOO GUIDE 
The American White Pelican (Pelecanus thrachrhynchus). 
The most familiar species in America. It is a very beautiful bird, 
and is rarely seen further east than Cape Hatteras. It is quite 
common on the Gulf coast. 
The Brown Pelicans are abundant in Florida, and are widely 
spread over the swamps and large lakes in that State. Their 
food in captivity consists entirely of fish. 
The European Pelican (Pelecanus onocrotalus). Found in 
many parts of Africa and Asia, as well as in Europe. It is 
characterized by an extremely large pouch, capable of holding 
nearly a half gallon of water. 
HERONS 
Like storks and ibises, are generally large, having long necks 
and tufts of feathers on both sides of the breast and posterior 
parts of the body. When they fly they double their necks and 
stretch back their legs. They feed on fish, reptiles, frogs, snails, 
slugs, and insects. They are often seen standing in the water, 
watching for prey that may come within reach of their spear- 
shaped bills. 
The Great Blue Heron (Ardea herodias). This is a very 
familiar bird in the eastern part of the United States. It is also 
common in South Africa. It has a sharp, conical-shaped bill, 
with which it pierces its prey. It varies greatly in plumage and 
measurements. 
Cranes. Cranes are found in warm countries. Their migrations 
are long. They have long, slender legs and plume-like feathers. 
Visitors to the Zoo are greatly amused by the grotesque appear¬ 
ance of these long-legged birds. The common crane is about 
four feet in height. There are several species of these birds. The 
most notable in our collection are the Stanley crane and the 
sand hill crane. 
The cranes, blue herons and pelicans are all taken to the 
Winter Quarters in winter, but the other birds remain here the 
entire winter. The ice is kept broken in places for their benefit, 
and sometimes, when the weather is extremely cold, the keeper 
throws straw on the island and they stay on that.
