another nest, the proprietors of which were feeding it as if it had been their own : I am sure 

 of this fact, because there was no other nest near it containing two young birds. Some of the 

 eggs were quite fresh, while others had been so far sat upon that we could not blow them ; and 

 many of the young birds must have been hatched some two or three weeks. We regarded 

 these birds as the Falcons of the sea, for we repeatedly saw them compel the Terns, Boobies, 

 and Gannets to disgorge their prey, and then adroitly catch it before it fell to the ground or 

 water. We never saw them settle on the water, but constantly soaring round and round, appa- 

 rently on the watch for what the smaller birds were bringing home. I have found in their 

 pouch young turtles, fish, cuttlefish, and small crabs."
