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.
Kitchen-middens of England, Ireland and Denmark reveal the existence of the capercally, Tetrao urogallus, and of the great auk or gare-fowl, Alca impennis; both species long since vanished from those countries.
The Bulletin of the Nuttall Ornithological Club was published from 1876 to 1884, when it was superseded by The Auk.
Hence anAu = auk t a22a33...ann, where the cofactor of an is clearly the determinant obtained by erasing the first row and the first column.
A special interest attaches to the great auk (Alca impennis), owing to its recent extinction and the value of its eggs to collectors.
