Food parasitism occurs when an individual of one species steals an item of food from an individual of another species after the victimized individual has already located and caught the food. During a trip to Maine in 1968 we noticed that Common Terns, Sterna hirundo, on Petit Manan Island regularly pursued and stole fish from Arctic Terns, Sterna paradisaea, nesting on the same island. In 1969 we returned to this island to extend our observations of food parasitism and to obtain some…

Coloniality in Terns: The Role of Social Feeding
TLDR
Ward and Zahavi's (1973) "informationcentre" hypothesis predicts that, given equal habitat and predation factors, species which depend upon food that is unpredictable in space and time and/or distributed over large areas should nest in larger colonies than species feeding on a more uniformly-distributed food source close to the nest site.
Living with gulls
TLDR
Sandwich Terns are well adapted to the kleptoparasitic behaviour of their associative breeding species, and if they cannot avoid the attacks of the gulls by moving away from them, they increase their foraging effort and compensate for these losses.
Individual Foraging Strategies of Kleptoparasitic Roseate Terns
TLDR
Observations indicate that kleptoparasitism by Roseate Terns is a specialized behavior, used regularly by only a few individuals at this breeding colony, consistent with a recent theoretical prediction regarding kleptonitism in birds.
Food and Feeding Biology of the Common Tern during the Nonbreeding Season in Samborombon Bay, Buenos Aires, Argentina
TLDR
The diet of Common Terns, which breed in North America and migrate into the southern hemisphere in winter, show a wide nonbreeding distribution that includes the Atlantic coasts of Argentina and Brazil, was assessed by the analysis of regurgitated pellets collected at Punta Rasa.
Influence of diet and foraging strategy on reproductive success in two morphologically similar sympatric seabirds
TLDR
This study suggests that interspecific differences in diet and foraging strategies can support total reproductive output in morphologically similar species.
Resource partitioning in three congeneric sympatrically breeding seabirds: Foraging areas and prey utilization
TLDR
This study demonstrates the successful use of a visual tracking method to show how morphologically similar sympatric seabird species partition resources by diet, foraging area, and response to increasing brood age.
Do Co-Nesting Arctic and Common Terns Partition Foraging Habitat and Chick Diets?
TLDR
Overall, Arctic and Common terns at this site show foraging habitat segregation, but similar chick diets.
Feeding Behavior and Ecology of Colonial Waterbirds: A Synthesis and Concluding Comments
TLDR
A synthesis of foraging by both "marine" and the more "coastal" colonial birds is presented, using these Symposium contributions as examples.
Composition, spatial and temporal variation of Common and Arctic Tern chick diets in the Gulf of Maine
TLDR
Long-term diet data sets gathered from multiple sites are the best way to characterize waterbird diets and significant inter-annual and intercolony differences in the diversity and proportions of prey types were found.
CONTRASTING BROOD SIZES IN COMMON AND ARCTIC TERNS: THE ROLES OF FOOD PROVISIONING RATES AND PARENTAL BROODING
TLDR
The number of chicks that Arctic Terns could raise may have been limited not only by the rate at which parents could supply food to the nest but also by the requirements of chicks for brooding.

Predation and Piracy by Gulls at a Ternery in Maine
TLDR
It will be shown that a substantial number of chicks are now lost to the large gulls and that fish-stealing is likely to be significant when the terns find fishing difficult.
BODY SIZE, PREY SIZE, AND ECOLOGICAL SEGREGATION IN FIVE SYMPATRIC TROPICAL TERNS (AVES: LARIDAE)
TLDR
It is argued that the phenomenon of ecological segregation need not indicate the operation of competitive exclusion, and it is suggested that many natural habitats cannot be assumed to contain the greatest number of related species that could coexist there indefinitely if the opportunity to establish themselves arose.

The total number of species is proportional to the total range of the environment divided by the niche breadth of the species, which is reduced by unequal abundance of resources but increased by adding to the dimensionality of the niche.
