A Case of Cooperative Polyandry in the Common Tern

Waterbirds, 2004
Abstract The first case of cooperative polyandry in the Common Tern (Sterna hirundo) is reported. During the breeding season of 2000 two males, originating from the same brood, bred together with a female, who was paired in the previous season with one of the males. Both males copulated with the female.

DDE and reproductive success in some Alberta common terns

Canadian Journal of Zoology, 1973
A study of the relationship of DDE to reproductive success of an inland breeding population of common terns. Sterna hirundo, had been carried out in 1969 and 1970 at Chip Lake, Alberta. Although a continuing decrease of DDE residues in eggs bad occurred, eggshell thickness remained unchanged.

Divorce and asynchronous arrival in common terns, Sterna hirundo

Animal Behaviour, 1999
We investigated which of three hypotheses (better option, incompatibility or asynchronous arrival) best explains divorce in the common tern. One partner did not return the next year in 18.5% of 150 pairs. Among the 106 pairs in which both mates returned, the divorce rate was 18.9%.

Calibrating the telomere clock in common terns, Sterna hirundo

Experimental Gerontology, 2003
Field biologists often work with animals for which there are no prior history. A marker of an animal's age would offer insight into how age and experience affect reproductive success and other life history parameters. We previously reported that length of telomere restriction fragments shorten predictably with age in the captive zebra finch ...

Nocturnal behaviour of breeding Common terns

Ethology Ecology & Evolution
Breeding Common terns Sterna hirundo typically remain at the colony at night, yet nocturnal colony desertion may occur due to predation, nocturnal foraging, or prospecting. We used GPS telemetry data to investigate nocturnal colony attendance and movements of Common terns at multiple freshwater and marine colonies.

Factors in the Incubation Behavior of the Common Tern

The Auk, 1943
Hartert (Nov. Zool., 32: 147, 1925) says: "This peculiar bird is known only from the type specimen. It is very peculiar, the crown to the base of the upper bill nearly black, underside heavily striped. I am not sure about its relationship." Hartert and Steinbacher (V6gel pal. Fauna, Erganzungsband, 4: 374, 1935) says: ". . .

Effects of a rabbit on nesting common terns

Canadian Journal of Zoology, 1979
Reproductive biology of common terns (Sterna hirundo) was studied at an insular breakwater site at Port Colborne, Ontario in 1976 and 1977. The unusual occurrence of an eastern cottontail rabbit (Sylvilagus floridanus) in the ternery in 1977 disrupted nesting activity and nocturnal incubation attentiveness.

Geography and Seasonal Movements of the Common Tern in Australia

Emu - Austral Ornithology, 1965
The status of the Common Tern in Australian waters is examined in the light of specimen records from the mainland, Lord Howe Island, Torres Strait, and Papua, and of limited observations from Queensland, New South Wales, and Victoria. These data suggest that south-eastern Australia is a minor wintering area for the black-billed race, Sterna hirundo ...
