HAWAIIAN BIRDS. US 



spring of 1901. One of them was shot, but what became of the 

 other is unknown. It is possible that they were of the present 

 species, or they may have been one of the other west coast forms 

 that chanced to find their way here in company with the flocks of 

 ducks that each fall wing their way to the islands for the purpose 

 of wintering. 



Description.— Adult. Head and neck violet black with changeable re- 

 flections; rest of body greenish. In breeding dress, neck and rump with 

 white filamentous feathers; flanks marked with white. Juvenile birds of 

 a dusky brown. 



FAMILY SULID^'E. THE GANNETS. 



Sula cyanops (Sundev.). Masked Gannet. 



But one of .the gannets have been reported from the main group, 

 though the others may be expected to occur in the contiguous 

 waiters, at least casually. The present species breeds both on 

 Laysan and French Frigate Islands. No nest is made, but the 

 two eggs are laid on the sand. All the members of the family 

 live upon fish. 



Description. — Adult. White; wing-coverts and alulae sooty brown; tail 

 mostly sooty brown; feet yellowish. Length about 28 inches. The young 

 are brown above, lower parts white. ■ 



Sula piscator (Linn.). Red-footed Booby. 



Knudsen secured a specimen of this gannet on the coast of 

 Kauai, concerning which he says : "The other day, when the 

 men were out fishing, this bird came up to the canoe and tried to. 

 take the fish off their hooks." (Proc. U. S. Nat. Museum, Vol. 

 XII, p. 383, 1890.) 



This species is very plentiful on Laysan, as reported by Palmer, . 

 and was often seen, also, at sea. This and the following species 

 both make nests upon bushes. The red-footed booby is said to. 

 lay but one egg. (Rothschild.) 



Description. — Adult. White, head and neck with buffy tinge; remiges. 

 slate color; shafts of rectrices yellowish; feet yellowish. Length about 

 28 inches.
