Under the eaves and under the verandas of the houses are the nests of barn swallows, gray mud stippled up against a rafter, the fast-growing young almost crowding one another out. So gently familiar are these birds, and so little afraid of people, that one has built a nest under the frequented piazza of the big hotel, and the parent birds flit back and forth unconcerned by the rows of guests that often take chairs and watch the nestlings for long periods. Not only do the parents feed their young while thus watched by crowds but a few feet away, but they fly in under the veranda and capture food right over the heads of the promenaders with equal freedom from fear. Barn swallows are usually friendly, confiding birds. They seem here to have caught the sense of protection and safety which comes to all on the little island, and become even more fearless. It is much the same way with the tree swallows, which, having no hollow trees, build in bird boxes all about. These already have young in flight. Standing on the cliffs you see their steel blue backs as they swirl with the little waves in and out among the rockweed at low tide, seeking their food very close to land or water. Often the young sit on some safe pinnacle and are fed there, the old bird flashing up, twittering, delivering a message and a mouthful at the same time, then flashing away again, whirling and wheeling, never beyond call of the eager fledgling. Often the fledgling soars into space, hardly to be distinguished then from the older bird, and twitters back and forth near the parent. Then when the latter comes with a mouthful the former simply poises fluttering while the old bird dashes up, twitters and feeds, and is off again in the flash of an eye, so fleet of motion, so agile of turn, that it puzzles the watcher to follow the course of flight. At the bottom of the tide the rocks over which the tree swallows swirl with the waves are a golden olive with the sun-touched tips of the carrageen. Higher up the boulders lift their heads with the air-celled rockweed falling all about them like wet hair. Some of these tresses hang down in golden luxuriance, others are dark, almost black, as if blondes and brunettes were to be found among tide rocks as among men. Between these rocks are still pools of brine where mussels and crabs wait the deliverance of the full sea and kelp waves its long, dark-olive, ruffle-margined banners. Down among these with the ear close to the smooth, undulating surface you may catch the eerie plaint of the whistling buoy off the channel some miles to landward, telling its loneliness in recurrent moans.
