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 ...

Common Tern (Sterna hirundo) Use of a Staging Site in the Chesapeake Bay

Northeastern Naturalist
In 2021, we initiated fieldwork to assess the relative importance of a staging area for Sterna hirundo (Common Tern) at a pier at the confluence of the Patuxent River and Chesapeake Bay, MD.

Individual Black Terns Chlidonias niger and Common Terns Sterna hirundo can vary the degree of primary-moult completion from year to year

Ringing & Migration
Black and Common Terns can both suspend and arrest their primary moult, allowing them to adjust their moult to variation in environmental conditions. Both species arrest a second primary-moult series in Africa before migrating to Europe.

Individual Recognition by Auditory Cues in the Common Tern (Sterna hirundo)

Nature, 1970
IN many socially organized vertebrates, successful parental care depends on individual recognition1. Particularly with birds breeding in dense colonies there are clear signs that the basis for recognition may be mainly auditory rather than visual. In the sandwich tern (Sterna sandvicensis), for example2, the “fish call” used by the parent returning ...

Endocrine Patterns during Aging in the Common Tern (Sterna hirundo)

General and Comparative Endocrinology, 1999
Blood samples were taken from breeding common terns (Sterna hirundo) of known age during two successive breeding seasons to determine if plasma concentrations of estradiol, progesterone, androgen, and luteinizing hormone (LH) reflect the process of aging. Males and females were trapped and sampled once between laying of the first and the second eggs in

Intraspecific variability in isotopic composition of a monomorphic seabird, the Common Tern (Sterna hirundo), at wintering grounds

Emu (Print), 2019
Understanding sex differences in foraging behaviour has important implications for breeding biology and population ecology. This requires the evaluation of segregation throughout the annual cycle, including the non-breeding period.
