99. LARUS PHILADELPHIA, (Ord.} Coues. 

 (BONAPARTE'S GULL.) 



First observed August 9, and afterwards became very 

 abundant. About August 16 they began to assemble in 

 large flocks. This bird is sometimes eaten by the inhabi- 

 tants, although the flesh is exceedingly fishy. 



ioo. STERNA HIRUNDO, L. 

 (COMMON TERN.) 



A very abundant species everywhere. During my daily 

 excursions along the shore this beautiful little bird was 

 always to be met with, sometimes sailing over me uttering 

 its harsh scream of anger, or again holding itself suspended 

 in the air, with head bent down and expectant gaze, watch- 

 ing for the reappearance of some small fish which it had 

 caught sight of. This is the only representative of its family 

 that breeds on the islands, at least the only one which was 

 found, and was the only species taken during July and August. 



Breeds abundantly on some of the islands.
