The island of Annet (i.e., Little Agnes) is the largest breeding-ground. It is a low-lying, sandy tract, serpentine in shape, rising towards the north to a height of sixty feet, and surrounded by dangerous rocks. It is covered with bracken and tufts of the sea-thrift, which latter is in full flower during the breeding-season, making a bright pink background for the white and black plumage of the birds.
Annet is known by the name of “Bird Island,” from the immense numbers that breed there. In the early summer the sea all round is black with puffins and razor-bills, their white breasts being hardly noticeable as they sit on the surface of the water; and the air above is dark with clouds of gulls, and full of their ceaseless cry. Puffins (also called sea-parrots) have bred on the islands from time immemorial. An old name for them was “Coulter-neb,” from the peculiar shape of their beaks, which were thought to resemble the coulter of a plough.
They were formerly much esteemed for food, chiefly pickled and salted, because by this means their rank and fishy flavour was disguised; and one imagines the three hundred puffins payable at Michaelmas for the rent of the islands in the time of Edward I. must have been destined for treating in this way rather than for eating fresh.
William of Worcester, writing in 1478, records the presence of “pophyns” on Rascow (i.e., Tresco); and Richard Carew (1602) says: “The Puffyn hatcheth in holes of the cliffe, whose young ones are thence ferreted out, being exceedingly fat, kept salted, and reputed for fish, as comming nearest thereto in their taste.”
Their flesh used to be allowed by the Church on Lenten days.
It is a most ludicrous-looking bird during the breeding season, for then its beak becomes enlarged to double its usual depth, quite out of proportion to the dimensions of its owner. And not only is the size of the beak remarkable, but it is gorgeously coloured with carmine, blue-grey, and yellow; so that for a bird which carries a sober yellow-brown beak all the winter it must be almost embarrassing to appear in such a garish guise! The legs are a bright orange-red, a ring of carmine encircles the eye, and altogether, with his black coat and white waistcoat, he presents a very striking appearance.
The puffin is entirely an oceanic bird, only coming to land to breed. It lays its solitary egg at the end of a long burrow dug in the sand or peat. The isle of Annet is simply honeycombed with these burrows, so that it is impossible to walk even a few steps without finding the ground give way beneath one’s feet, and sinking, sometimes knee-deep, into the soft soil. The springy tufts of sea-pink which cover the island offer more resistance and a firmer foothold than the sandy earth.
By the end of April the birds are busy digging a new hole with their sharp nails, or overhauling that of the previous year. In making the hole they throw themselves upon their backs, and with their bills and claws burrow inwards, until they have made a hole perhaps eight to ten feet long, and sometimes with several windings and turnings.
A week or ten days after the hole is ready a single round white egg is laid. Both birds assist in digging the burrow, and also in hatching, which takes about a month. Sometimes a forsaken rabbit-hole will save the pair the labour of digging out a habitation for themselves; and occasionally, where a spot between three stones has been carefully chosen for excavation, one may see a lintel and door-jambs of granite forming the entrance into the burrow! Puffins and Manx shearwaters will sometimes share the same hole; or they will have a common entrance with passages branching out in several directions, as in some of our “desirable residential flats.”
They feed their young on the fry of certain fish, and are particularly fond of the lance, or sand-eel. The parent bird may be seen returning to the burrow, with numbers of small fish hanging from its bill. How it could retain its hold of, say, the first nine caught while capturing the tenth used to be a subject for wondering conjecture: but an examination of the inside of the beak has shown an arrangement of barbed hooks projecting backwards, on which each fish is speared as it is caught. The discovery of this wonderful provision of Nature is due to Mr. C. J. King of St. Mary’s.
