THE DIVIN(} BIRDS — PYUOPODES. 



It 



southern limit of this species during the breeding-season. Among these ishinds it 

 is (juite numerous, breeding in the caves and hollows of the generally inaccessible 

 cliffs. Noticing, early one morning, many of these birds, frightened by the report 

 of his gun, issuing out of a ravine hemmed in by high rocky cliffs and terminating 

 in a low, narrow cave, Mr. Hensliaw gained access to the latter, a' id succeeded in 

 finding their eggs. No nest at all had been jjrepared for tliese, bui. they liad been 

 deposited on the sandy fioor of the cavern, and at its farther end, where it was so 

 dark that he could not see them without the aid of a light. Other pairs had availed 

 themselves of the nooks and fissures in the face of the wall, laying their two eggs 

 on the bare rock, lie was able to find but a few of the many eggs that must have 

 been there, as the shelves of the rocks were in most instances too high to be reached. 

 The birds submitted to this pillage without a murnuir, though not without solicitude, 

 as was evinced by the anxious manner in which they swam back and forth at tlu! 

 entrance to the ravine, keeping well out of gunshot. lie describes their eggs, when 

 fresh, as having a faint greenish white ground, spotted, mostly at the larger end, 

 with irregular blotches. 



Eggs of this specicis are in the Smithsonian collection from Coal Harbor, Alaska, 

 T'uget Sound, Kadiak, and the Farallones. The ground-color varies from a glaucous 

 white to a deep butt". The nuirkings are a deep warm tint of claret-brown, deepening 

 into blackness, in bold, large blotches interminghul with smaller, subdued cloudings 

 of a faint lavender and puri)lis]i slate. Two eggs in my own collection, from the 

 Faralloues, measure : 2.30 by 1.70 inches ; 2.45 by 1.G5.
