QUANTIFYING DISTURBANCE FACTORS AND EFFECTS IN COMMON TERNS (STERNA HIRUNDO) USING VISUAL, AUDIO, AND REPRODUCTIVE DATA
The common tern is designated as a species of special concern in Upstate New York. The largest inland tern colony in New York is located on Oneida Lake, which is habitat to many other colonial waterbird species and an area of high human use during the tern breeding season. In addition to …

Foraging ecology and parental care of common terns (Sterna hirundo) nesting in Windermere Basin, Lake Ontario
The relationships among chick feeding, size and type of prey item, and foraging time away from the brood have not been well studied in seabirds. This study investigated spatial and temporal patterns of foraging and chick-provisioning among 23 radio-tagged male common terns nesting at Hamilton …

„The spatial and temporal link between Common Terns Sterna hirundo and their prey fish in the Wadden Sea“
Der Einfluss räumlicher und zeitlicher Verteilungsmuster von Fischen auf die Reproduktion von Flussseeschwalben im Wattenmeer wurde untersucht. Langfristige Veränderungen des Bruterfolges konnten mit der Heringsabundanz in der Nordsee erklärt werden. Die Nahrungsfischdichte hatte einen größeren …

Nest-site selection, nocturnal nest desertion, and productivity in a common tern (<i>sterna hirundo</i>) colony at Detroit River, Michigan
<p>Common terns are declining in the Great Lakes region and represent a population relatively distinct from that of eastern North America. On an artificial site, I studied the substrate and vegetation preference and productivity of nesting terns at two scales: general habitat and nest-site. Terns …

Floating seaweed as ephemeral neustonic habitat
… shift towards surface pecking and dipping in Sterna hirundo. The association behaviour of the encountered species and their (optimal) use of the transient resources offered by floating seaweeds potentially have important ecological consequences, like for example the passive dispersal of …

Parental care in the common tern (Sterna Nirundo): sexual roles in a monogamous seabird
… behaviour of male and female Common Terns (Sterna hirundo) was documented throughout two breeding seasons at a colony near Port Colborne , Ontario. Thirteen and fourteen pairs of terns were chosen for intensive study in 1982 and 1983, respectively. The delivery of fish by males to their …

Potential Interaction Analysis of Offshore Wind Energy Areas and Breeding Avian Species on the US Mid-Atlantic Coast
… collected GPS location data on common terns (<em>Sterna hirundo</em>) at Dawson Shoals, Virginia during their 2017 nesting season. We analyzed their movement and behavior in relation to offshore wind sites. We determined that common terns most often utilized an area roughly half the size of the …

Life History Variation of Common Terns in the Gulf of Maine
… conditions.</p> <p>Common tern (<em>Sterna hirundo</em>) life history phenotypes vary between islands in the Gulf of Maine. Common terns on offshore islands (>10km from mainland) and nearshore islands (5 to 10km from mainland) lay smaller clutches, hatching chicks with slower growth …
