THE LIFE OF THE ABARY SAVANNAS.

Attention is called to the apparent immobility of the crest, 

 which is as fully erect in the crouching Hoatzin (Fig. 155) as 

 in the same bird a minute or two later, alert and about to fly 

 (Fig. 156). 



Thus it was that we took the first photographs ever made 

 of these most interesting birds.

Insects were abundant on the island and if we had taken 

 time we could have made an interesting collection. Three 

 species of bright Orange butterflies were numerous (Euptoieta 

 hegesia, Colaenis phaerusa and the familiar Red Silver-wing, 

 Agraulis vaniUae, of our northern fields), and \vith these were 

 also a White (Pier is monuste) and a Yellow (Callidryas statira).
