The southern coast and its inland waters are frequented by several species of petrel, among which are the Procellaria gigantea, whose strength and rapacity led the Spaniards to call it quebranta huesos (breakbones), the Puffinus cinereus, which inhabits the inland channels in large flocks, and an allied species (Puffinuria Berardii) which inhabits the inland sounds and resembles the auk in some particulars of habit and appearance.
Of those species that frequent the North Atlantic, the common StormPetrel, Procellaria pelagica, a little bird which has to the ordinary eye rather the look of a Swift or Swallow, is the "Mother Carey's chicken" of sailors, and is widely believed to be the harbinger of bad weather; but seamen hardly discriminate between this and others nearly resembling it in appearance, such as Leach's or the Fork-tailed Petrel, Cymochorea leucorrhoa, a rather larger but less common bird, and Wilson's Petrel, Oceanites oceanicus, the type of the Family Oceanitidae mentioned above, which is more common on the American side.
