NORTH AMERICAN FAUNA. 



[No. 7. 



The male Costa's hummingbird has a peculiar habit, probably 

 closely associated with the season of courtship, of flying up in the 

 air to a considerable height and then swooping down with great ve- 

 locity until near the ground, when it rises to its former position, to 

 repeat the manoeuver fifteen or twenty times before settling on some 

 perch to rest. The course taken by the bird forms a parabolic curve, 

 and when on the descent a booming, rushing noise is made, which can 

 be heard at a considerable distance.

Calypte anna. Anna's Hummingbird. 



A large hummer was seen in the Oajon Pass in the San Bernardino 

 Mountains on January 2, which was probably this species. Mr. Stephens 

 saw a number, mostly immature males, on the side of Eeche Canon, 

 September 22-24; Mr. Bailey found the species common at Monterey, 

 where he secured specimens October 3 and 6, and Mr. Nelson found it 

 common at Morro Bay, and saw a few south of that place in November.
