Population dynamics, recruitment, individual quality an d reproductive strategies in Common Terns Sterna hirundo marked with tran sponders

Common Tern (Sterna hirundo) Science Article 2 abstract From 1992 to 1999, we used subcut aneously injected transponders, enabling remote an d automatic annual identification with the aim of performing an integrated population study of a Common Tern Sterna hirundo colony. Within a few years, population parameters an d their inter-year variation could be calculated […]

Growth and energetics of chicks of the sooty tern (sterna fuscata) and common tern (s. hirundo)

Common Tern (Sterna hirundo) Science Article 7 abstract We measured the energy budgets of chicks of the Common Tern (Sterna hitundo)on Great Gull Island, New York and of the Sooty Tern (S. fuscata) on the Dry Tortugas, Florida. The respiratory energy requirement was determined by measuring oxygen consumption in a closed system. We calculated the […]

Some observations on the occurrence of three generations of primaries in Common Terns Sterna hirundo

Common Tern (Sterna hirundo) Science Article 3 abstract In adult Common Terns Sterna hirundo, the post-nuptial primary moult begins either near the breeding grounds (Cramp 1985) or upon arrival at the wintering grounds (L Underhill pers comm). Moult starts with the innermost primary (p1, numbered descendantly) and all birds initiate moult by October (Cramp 1985, […]

Individual quality and recruitment in the common tern, Sternahirundo

Common Tern (Sterna hirundo) Science Article 4 abstract We investigated the individual histories of more than 1 300 fledglings from an intensively studied colony of commonterns, Sterna hirundo. Based on six cohorts (1992-1998), which had recruited almost completely by 2002, we found that thebody mass of a fledgling was positively related to return and recruitment […]

Population dynamics, recruitment, individual quality and reproductive strategies in Common Terns Sterna hirundo marked with transponders

Common Tern (Sterna hirundo) Science Article 6 abstract From 1992 to 1999, we used subcutaneously injected transponders, enabling remote and automatic annual identification with the aim of performing an integrated population study of a Common Tern Sterna hirundo colony. Within a few years, population parameters and their inter-year variation could be calculated with a high […]

Body mass fluctuations and mortality in Common Tern Sterna hirundo chicks dependent on weather and tide in the wadden sea germany.

Common Tern (Sterna hirundo) Science Article 5 abstract In three Common Tern colonies in the German Wadden Sea the relationships between mortality, body mass of chicks, weather and the tide-dependent change in the daily span of time favourable for feeding (TFO-DH) were studied. On the island Oldeoog weather fluctuations between years were more pronounced and […]

Responses of nesting common terns and laughing gulls to flyovers by large gulls

Common Tern (Sterna hirundo) Science Article 8 abstract Disturbance can reduce productivity by disrupting nesting behavior. We examined responses of nesting Common Terns (Sterna hirundo) and Laughing Gulls (Larus atricilla) to frequent overhead flights by Herring (L. argentutus) and Great Black-backed (L. murinus) gulls to determine if such flyovers may have contributed to declines in […]

Brood size and food provisioning in Common Tern s Sterna hirundo an d Arctic Terns S . paradis a: consequences for chick growth

Common Tern (Sterna hirundo) Science Article 1 abstract Food provisioning rates and chick growth rates of Common Te rns Sterna hirundo and Arctic Tems S. paradis a were studied in Northeast Engl and. Adult tems of both species fed large broods more frequently th an those containing fewer chicks . Energy supply per nestling declined […]
