204 ZOOLOGICAL RESICARCHES 



to the virgin forest , where it lives , in companies of five 

 or six specimens together, in the crowns of the highest 

 trees, generally out of reach of gunshot. There they play 

 together, especially in the morning and evening, running 

 along the branches to a somewhat exposed point where 

 they proudly stretch out their necks , spreading their wings 

 and flapping up and down their fan-like tails , uttering , 

 at the same time, a clamorous cry , like »cooruah , cooruah, 

 rook, rook, rook". Probably on account of its pride, the 

 Liberians call it » pea-cock" or » pea-fowl". It feeds upon 

 a kind of bush-plum and other wild fruits , of which an 

 enormous quantity is sometimes found in its crop.

The palm-bird, as the Liberians call it on account of 

 its principal food , is , like many of its congeners , a very 

 noisy bird. It keeps commonly in the highest forest-trees , 

 from whence it visits the oil -palms when the palm-nut- 

 season is at its highest (February-May). They live in small 

 families together but seem , when the nestlings are able 

 to keep on the wing and food begins to get scarce in the 

 country , to form large flocks , swarming through the fo- 

 rest but coming back to a regular sleeping-place. We were 

 once fortunate enough to come upon such a spot and were 

 much struck by the lowness of the roosting-places they 

 had chosen. This place was a swamp , surrounded by hills
