The Individual

Abstract1. There is a considerable amount of observational evidence to show that in a number of bird species, especially colony-nesting sea birds, a bird's recognition of its mate and the mutual recognition of parent and young may, in certain circumstances, be based upon individual peculiarities of voice. However, with the exception of a preliminary account of the matter in the Guillemot, (Uria aalge), there is no analytical evidence to support these conclusions. 2. The Sandwich Tern (Sterna sandvicensis) provides good opportunity for study of one aspect of this problem, namely the individual distinctiveness of the 'fish-call' of the returning parent bird. Different individuals were recorded and the results analysed by sound spectrograph. 3. The fish-call is shown to be composed of three segments of sound; each segment displaying individual characteristics of duration, fine structure, pitch etc. The overall relations between them, the "patterning" of the call, is also shown to be characteristic. 4. The extent to which these separate individual characteristics are recognised as distinctive by birds themselves has not been investigated but it is clear that if the fish-call is to be used as an effective means of individual recognition in a large colony the patterning of the call (in the sense of the 'gestalt' or the overall relationship of the component parts) must play a major role.

Care Allocation

We studied parental-care allocation by males and females in three tern species. Female Common Terns (Sterna hirundo) and Little Terns (S. albifrons) performed more incubation and brooding than males, whereas in the Sandwich Tern (S. sandvicensis) the sexes shared these duties equally. In all three species, agonistic behaviors were performed equally by females and males. Prey types brought by males and females of each species were similar, but males tended to bring larger prey and had higher delivery rates than females. Information on parental-care allocation by female and male seabirds of various species, 5 gulls, 6 terns, and 1 skimmer, indicates that females perform most of the incubation and brooding in both gulls and terns, whereas males perform most territory attendance and agonistic behavior (gulls) and more prey provisioning (terns). These patterns are qualitatively consistent with the explanation that the differences between gulls and terns in sex-biased parental care are related to the fact that gulls exhibit sexual size dimorphism but terns do not. Contrary to theoretical predictions that in monogamous birds, females contribute more reproductive effort than males, in all the seabird species studied so far the total parental expenditure by males seems to equal or outweigh that by females.
