 IVoni its armed wing can be struck ■\\'itli considerable force. The bird is not, however,

The food of the Horned Screamer consists chiefly of vegetable substances, such as the 

 leaves and seeds of aquatic plants, in search of which it wades througli tlie reptile- 

 haunted morasses. Its flight is strong and easy, its walk is erect and bold, and its

Another well-known example, the Crested Screamer, or Chaja, is a finer-looking

It is a native of Brazil and Paraguay, and is generally found near the banks of rivers. 

 It is a shy and generally solitary bird, being mostly seen singly, sometimes in pairs, and 

 now and then in small fiocks. Like the horned Screamer, the Chaja is armed with two 

 spurs on each wing, and can employ them to such purpose, that it can drive away even a
