 shore birds and other birds. Large falcons

apparently of this species have been seen at 

 several places in the Zone, but especially at the 

 Pacific canal entrance. On April nth, 1926, 

 one was seen to chase and dive six or eight times 

 at a turkey buzzard (Cathartes aura), for what 

 purpose I do not know, unless for diversion. 

 The buzzard apparently had no difficulty in 

 avoiding its attacks, though made very swiftly 

 from a great height, by turning and side slipping 

 at the last instant.
