Abstract The prey displayed to mates and delivered to chicks by nesting Gull-billed Tern (Sterna nilotica) was studied in a colony on a coastal lagoon in eastern Spain during 2003. During 31 hours of observations, 1,091 prey items were observed. The trophic resources exploited by the species and seasonal differences in prey composition within the same breeding season were examined. Red Swamp Crayfish (Procambarus clarkii) was the main prey species (64% of prey items), followed by insects (17… 

Insectivory versus Piscivory in Black Terns: Implications for Food Provisioning and Growth of Chicks

It is concluded that adults were able to raise chicks through age 12 d at comparable growth rates with insect- or fish-dominated diets, and the capability to use both fish and insects may reduce potential variability in food availability during the breeding season.

The foraging ecology of Caspian Terns (Hydroprogne caspia) on Peel-Harvey Estuary, south-western Australia

The results of this study highlight the significance of the Peel-Harvey Estuary for the conservation of H. caspia in south-western Australia and the connectivity between the birds on the Estuary in the non-breeding period and those on Penguin Island during the breeding season.

Mudflat Use and Predation on Male Southwestern Atlantic Fiddler Crabs (Uca uruguayensis) by Gull-billed Terns (Gelochelidon nilotica)

The use of a southwestern Atlantic mudflat in Argentina and depredation of the southwestern Atlantic fiddler crab (Uca uruguayensis) by Gull-billed Terns are documents.

Patch use and departure rules by gull-billed tern Gelochelidon nilotica

Following several capture attempts by terns, crabs hide, producing a temporary decrease in their availability, forcing tern departure from the patches, which are no longer profitable, suggesting that the marginal value theorem may not necessarily apply when prey availability is affected more by predator activity than by consumption.

Long-term changes in the food resources of a guild of breeding Ardeinae (Aves) in Italy

The diet of five species of herons and egrets changed sharply after 1995, with the bulk of the diet now made up of completely new prey species, in particular the allochthonous Louisiana crayfish and Oriental weatherfish, that only recently colonized the study area.

Synthèse des connaissances sur le régime alimentaire de la Sterne hansel Gelochelidon nilotica en région méditerranéenne

It is confirmed that the Gull-billed Tern is an extremely opportunistic feeder and has adapted to a variety of habitats, helping to explain its cosmopolitan distribution.

Food and foraging rhythm of a specialized Gull-billed Tern population Gelochelidon nilotica

Gull-billed Terns nesting in the Valli di Comacchio (Northern Italy) fed their chicks mainly with lizards, while fish and insects were less important, and the tern switch to alternative prey in relation to the rhythm of their availability.

CHARACTERISTICS OF FORAGING HABITATS AND CHICK FOOD PROVISIONING BY TROPICAL ROSEATE TERNS

It is suggested that food is unpredictable on a daily and seasonal basis in tropical Roseate Terns on Aride Island, Seychelles, and the high daily variations in the amount of food brought to chicks, intermediate periods of low food delivery, and an apparent seasonal decline in the number of food items brought to the colony suggest thatfood is unpredictable.

Winter Breeding by Black-crowned Night Heron in Eastern Spain

Winter breeding by Black-crowned Night Heron in l’Albufera de Valencia, Spain, during three consecutive years is described, and it is suggested that the abundance of the introduced Red Swamp Crayfish increased food availability when rice field were ploughed in early winter, and mild temperatures may have encouraged them to extend their presence into the winter season.
