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, 
100. 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.
