Bird-Lore, Volume I—1899

by Various

It was the 21st of May when I first peeped in upon the little bracket against the chimney wall that became the stage for the enactment of scenes filled with absorbing interest to me in the weeks that followed. It was not placed in an angle, but against the north side of the flue, beneath a slight projection formed by an accumulation of soot.

In a week one egg was apparent, but there may have been others, for the little builders had been adding one twig after another to the front edge of the nest, so that it had become impossible to see the bottom. Two more days passed, after which it could be seen that there were at least two eggs, and yet the structure continued to be enlarged.

June 5 marked the beginning of incubation. In mid-afternoon of this day I saw the sitting bird had flown, and, going out-of-doors to study birds, my attention was attracted to a Swift flying among the branches of the locust trees near by. This was an unusual sight to me, and, recalling that I had read that Swifts never alight in trees, I watched eagerly to see what it might mean. Soon I saw that the bird was snatching at little dry twigs. She flew round and round, and presently was gone. Suspecting that it was my little friend, I ran quickly upstairs, and sure enough, there sat my bird upon the nest, with a twig in her mouth, panting as if tired by extra exertion. Resting a moment, she proceeded to apply the salivary glue and adjust the twig, and then settled again to the task of sitting.

After a few days there came a cold storm, and it was believed that the little brooder proved unfaithful to her duties, for late one evening and early the following morning she was seen huddled with others of her kind beneath the nest. Great were my fears that no birds would ever come from these chilled eggs, but time made it clear that the tiny creature knew what she was doing. This was the sole act of parental neglect that was apparent during all the weeks required to rear the family. Under date of June 17, I noted that the eggs were constantly protected. At whatever time of day I looked I saw a sitting bird.

June 24 dawned fair and warm. As was my custom, I called to say "good morning" into the chimney before going down to breakfast, when I found that there was excitement in the little home. A faint peep reached my ear, which caused the mother anxious restlessness each time it was repeated. From half-past eight until ten o'clock that morning I sat at my post of observation, during which time it appeared that two or three more young were hatched, for there was much peeping on the part of the little ones and much fidgeting about by the adults. Two shells, or parts of shells, were tossed from the nest. Occasionally the parents exchanged places, one brooding the infants while the other went out into the air. Even at the tender age that must be reckoned by minutes, these young birds were fed, seemingly, by regurgitation.

During the progress of my study I found that one of the pair, which from manners and appearance I judged to be the female, had lost a tail feather, and this one I affectionately dubbed "Swiftie." She appeared worn out with anxiety added to the confinement of a long period of incubation, and embraced every opportunity to rest, but seasons of sleep were of short duration, for it seemed that the body of the brooding bird was lifted each time a movement was felt beneath. The mate, with his sleek coat, bright eyes and calm demeanor, formed a decided contrast to the ragged, unkempt appearance of the female.

Even four days showed perceptible growth in the swiftlings. They were not allowed to remain uncovered, a wise precaution, for their bodies were perfectly naked. At this age the instinct of cleanliness began to assert itself. The weak, awkward little creatures would struggle backward from beneath the brooder, up to the edge of the nest and deposit over it that which, remaining within, would have made their home uninhabitable.

From this time forth a third Swift was seen to enter into the care of the nestlings, taking its turn at brooding and feeding. Was this a nurse-maid employed to relieve the overburdened mother, or a kind and helpful friend or neighbor, or the younger and less care-taking of two wives? Who can tell?

It was not until the sixth day after hatching that I knew to a certainty how many young birds there were. Then, to my surprise, I found there were five. They had grown to be very clamorous for food. Two, at most three (later but one), were served at one feeding, and the process was after this manner: "Swiftie" would drop into the chimney and alight below the nest, her throat bulging with the fullness of captured insects. The little ones that were hungry were alert, for all had learned that a rumbling noise in the chimney, followed by a sound of "chitter, chitter, chitter," meant something to eat. After resting a moment, the mother would scramble up over the nest, and, with closed eyes, feel about until she came in contact with an open mouth, whereupon she would place her beak far down the throat, deposit a portion of food, then seek another yawning cavity. No system appeared to be observed in the matter of feeding. The hungriest youngsters made the greatest effort to reach the source of supply.

July 1 feathers began to appear. They grew rapidly, especially those of wings and tail, and in a week the bodies were about covered. With feathers came employment, for they must often be dressed, though from a habit of yawning frequently, common to the family, one might be led to believe that time hung heavily on their claws.
