DEPARTMENT OF BIRDS. 
C. William Beebe, Curator. 
In this department the leading event of the year was the as- 
sembling of a large collection of North American song-birds in 
an addition to the Large Bird House, which is known as the Glass 
Court. The thirty-nine large cages of that structure provided 
accommodations for a great number of passerine birds, and they 
were promptly filled. The song-birds previously quartered in 
the noisy parrot-room of the main building, and handicapped by 
their screaming neighbors, were removed to the new cages, 
where they were able to exercise their powers of song. Of the 
nineteen families in the Order Passeres, eighteen are repre- 
sented by living specimens, the majority of which are ranged, 
by Families, in zoological sequence. 
There is cause for satisfaction in the fact that on December 31, 
1906, the Zoological Park. contained living examples of 26 
Orders of Birds out of the total 31 Orders. The net increase 
over the bird collection of 1905, is 136 species, and 549 specimens, 
making a grand total of 2,104 specimens. The birds of the United 
States are represented by about 170 species, of which about 
70 belong to the Order of perching birds. 
Throughout the year, the collection of wild geese was made a 
special feature. A representative series was installed in the Ducks’ 
Aviary, for which large descriptive labels were prepared and dis- 
played. The series contained seventeen species out of the world’s 
total of thirty-five species, and it attracted much attention. 
The owl collection was enriched by the addition of a fine pair 
of giant eagle owls, and also tawny, Cape eagle, horned, and 
grass owls, and European little owl. Other important additions
