REPORT OF THE 
DIRECTOR OF THE ZOOLOGICAL PARK 
TO THE BOARD OF MANAGERS. 
HE year 1911 was marked by substantial advancement along 
several lines. The installations for animals gained im- 
portant additions, the animal collections were greatly strength- 
ened by new accessions, and the health of the animals continued 
to be satisfactory. 
NEW INSTALLATIONS FOR COLLECTIONS 
The Zebra House.—The old moose range has been dedicated 
to the wild horses and zebras of the world; and the site is well 
adapted to the purpose it is now about to serve. The Zebra 
House itself, an excellent brick structure, one hundred and 
seventy-four feet long by thirty-six feet wide, contains twelve 
box stalls and a series of yards connecting therewith on the east. 
In addition to this, two log barns are situated a few rods west- 
ward, each of which is surrounded by large corrals. These barns 
are intended for wild horses and other wild equines that have 
been acclimatized here and are known to be able to withstand 
our winters without detriment to their health and comfort. ' 
The Zebra House, exclusive of the yards, has been erected 
by Joseph Balaban, at a cost of $25,181 for the original contract, 
to which additions have been made. 
The Hagle and Vulture Aviary.—In accordance with an 
imperative duty and a long-cherished plan, early in 1911 the 
Director and Civil-Engineer Beerbower designed an adequate 
aviary to accommodate the eagles and vultures of the world. 
Up to this time, a fine collection of the larger birds of prey has 
been scattered throughout the Park, from the Ostrich House to 
the Aquatic Bird House, without distinctive character, and 
therefore quite unappreciated. Moreover, the temporary quarters 
of the birds of prey at the Aquatic Bird House always have been 
lamentably inadequate. 
Occupying the semicircular hillside that originally was used 
as a caribou range, there now stands an aviary that is fully up to 
the standard of our other installations. It is 208 feet long, and 
its depth from front to rear is, in the main, thirty-three feet. It 
consists of thirteen cages, seven of which are very large and six 
are of smaller size. The interior of the central, and largest cage 
is twenty-four feet wide, thirty-three feet deep and thirty-two
