No. 21.—THE AVIARY. 
Pending the construction of a new Aviary at the south¬ 
eastern end of the Garden, between the Lake and Thirty- 
fifth street drive, the collection of birds will be found much 
crowded. 
The order Passeres , or Perching Birds, is the largest and 
most comprehensive of all the higher groups, and includes 
almost all our songsters. In fact, a very large proportion of 
the smaller birds which are /amiliar in 'our midst][will be 
found classed within its limits. 
The Thrushes are represented here by the Wood Thrush 
(Turdus mustelinus) of America, the Robin ( Turdus migra- 
torius ), the English Blackbird ( Turdus meruld ), the Mock¬ 
ing Bird ( Turdus polyglottus ), the Cat Bird ( Turdus caroli- 
nensis ), and a number of other species.
