THE LIFE OF THE ABARY SAVANNAS. 375 



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 look the first photographs ever made 

 of these most interesting birds.

Insects were abundant on the island and if wc had taken 

 time we could have made an interesting collection. Three 

 species of bright Orange butterflies were numerous (Euploieta 

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

 Agraulis vanillae, of our northern fields), and with these were 

 also a White (Pieris monuste) and a YtWo^'iCallidryas statira).
