 chiefly ai'ound larger end, with browns. 



Food. — Mainly reptiles and insects. 



The swallow-tailed kite lives inaiuly on the wing and by virtue of 

 its long tail lias a remarkably graceful flight. When hunting it 

 flies close to the ground like a marsh hawk, but at other times sails 

 above the treetops, sometimes so far above that it takes a good eye 

 to see it. The kite picks up both food and nesting materials while 

 on the wing, carrying its food in its talons and eating as it goes. 

 Its call-notes have been given as a shrill, keen e-e-e or we-ice-we, uttered 

 in a high key which carries a long distance.
