Excerpt from Homing and Related Activities of Birds, And, the Acquisition of Skill in Archery, Vol. 7 In 1907, while the senior author was making a study Of the nesting behavior of the noddy and sooty terns at Bird Key, Tortugas, Florida, * the fact was Observed that these birds possess a well-developed homing sense. Only a few experiments were made at that time (see p. But the results were so promising that Dr. Alfred G. Mayer, Director Of the Marine Biological Station Of the Carnegie Institution of Washington, made special arrangements for the continuation Of the work in 1910, 1912, and 1913. Since the homing sea son is only 5 to 6 weeks in length (being limited to the laying and brooding periods), the present summary Of the three years' work is far from being satis factory. Notwithstanding Our failure to work out completely the problems Of homing in the terns, we feel that we have made so many improvements in our technique - in the matter Of caring for the birds on trips, locating them on return, etc., that it is advisable to report both what we have on homing and on the control of homing experiments. Some care has been taken in the pres ent investigation to supplement the 1907 work on the instinctive life Of the terns. This was found to be desirable in view of the fact that in the control Of the experiments on homing it becomes essential to have some accurate data on the ability Of the birds to swim and to remain on the water at night; the length of time the nesting impulse remains strong; the length Of time habits Of reacting to one nest and to one mate are retained, etc. The actual experi mental material On distant orientation will be given in detail, but the Observa tions upon the instincts and habits Of the birds will be presented in a more or less abridged form. On pages 34 and 35 we give the location Of Bird Key, a description of the colony Of terns dwelling there, and the complete setting Of our experimental work. Before presenting our own work we shall give in some detail the general historical setting Of the problem Of homing in vertebrates.

Excerpt from Homing and Related Activities of Birds, Vol. 7: The Acquisition of Skill in Archery The present series of studies on the behavior of birds is a direct outgrowth of an investigation made on the noddy and sooty terns nesting on Bird Key, Tortugas, Florida, by the writer under the auspices of the Marine Biological Laboratory of the Carnegie Institution of Washington in 1907 (publication 103). The homing "instinct" is the central topic in all the papers. In the 1907 investigation the fact appeared that terns possess a homing sense, behaving exactly as do homing pigeons when sent away from their nests and young. Such good subjects did the terns appear to be that it was soon decided to make this homing sense the chief object of the Tortugas researches. The topographical situation of Bird Key makes that island especially suitable for carrying out such experiments. In the first place, it is the northern limit of migration of these tropical birds. It becomes possible there to test whether the birds can home in a region never before, in all probability, visited by them. This can be accomplished by sending the birds anywhere north of Bird Key. Secondly, on account of the fact that Bird Key is the last body of land between the coast of Florida and the coast of Texas, the birds can be sent out for hundreds of miles over open water. There is thus afforded an opportunity for testing homing where apparently no "visual landmarks" can exist. These two conditions have never before been realized, and they are conditions which are indispensable in even a preliminary scientific study of homing. The 1907 investigation already referred to is concerned largely with instincts in terns - those of feeding, nesting, brooding, etc. It was necessary to have some survey made of these instinctive types of behavior before the homing instinct itself could be investigated. A part of the opening paper, pp. 35-45, in the present series gives much additional data on the nesting activities which have a bearing upon the control of experiments on homing. These observations are concerned with the instincts connected with the brooding of the egg, such as the number of shifts at the nest; retention of mate and nest habits; water habits and instincts, etc. It is thought that these observations, when taken in connection with those made in the first study, afford accurate means of testing the homing ability in these two species of terns. Having made the necessary investigation of the instinctive life of the terns, it became possible to carry out homing experiments. Preliminary experiments in 1910 (p. 47) showed clearly that in order to make a success of the work, some well-trained investigator would have to be sent out with the birds. In the 1910 work the terns were sent out with responsible men attached to the laboratory but who had had no training in feeding and caring for them. On account of this, usually something like half of the birds died en route, and the rest were released at the more distant points in very poor condition. In order to meet this difficulty, Dr. K. S. Lashley was asked in 1913 to associate himself with the work. The very successful returns from the second Galveston trip (p. 54) are due largely to his care of the birds on the forward journey. In addition to his invaluable aid in the problem of distant orientation, Dr. Lashley separately began a study of proximate orientation (p. 61), i.e., of the behavior of the terns in locating the nests, mates, young, etc. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
