DEPARTMENT OF BIRDS. 
In this department the most important events of the year were 
the beginning, and two-thirds completion, of the large Bird 
House, the completion of the Ostrich House, and the beginning 
of the Pheasants’ and Doves’ Aviary. The temporary Pheasants’ 
Aviary was removed and devoted to other purposes than the ex- 
hibition of birds, and the collection it had contained disappeared 
from exhibition. On account of the plans for the rebuilding of 
this aviary, no efforts were made to increase the collection, either 
by breeding or purchases. 
The completion of the Ostrich House, and its opening on De- 
cember 25th, afforded great relief to the Bird Department. Sev- 
eral weeks before the building was completed, it was filled by 
its legitimate occupants of the Order Ratitae—ostriches, emeus, 
rheas, and cassowaries—and a miscellaneous assortment of large 
land birds which had been crowded out of the Aquatic Birds’ 
House, and sorely needed comfortable shelter. The arrival of 
three delicate but very valuable deer from Paraguay made it 
necessary, for the preservation of their lives, to quarter them in 
the best place to be found for them, which proved to be in two 
of the Ostrich House cages,—where their lives were saved. 
A full description of the Ostrich House appeared in our Bulle- 
tin No. 16. Thus far this building has proven a most gratifying 
success. Although as light as the outside world, it is easily kept 
warm and comfortable, and its living inhabitants appear to enjoy 
life uncommonly well. The series of cages with high floors dis- 
play their contents better than those which are on a lower level. 
A fine series of descriptive labels, a chart of the Order Ratitae 
and several large drawings of allied fossil birds, all prepared by
