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 […]

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 […]

American Golden Plover (Pluvialis dominica) Science Article 8 abstract American Golden Plover (Pluvialis dominica) has the fame of making a long transoceanic flight in autumn from Nova Scotia to northern South America and after a short stop proceeding to its winter quarters in Argentina. In spring the birds are said to return in a long […]
Morphometric features of Pacific and American Golden-Plovers withcomments on field identification.
American Golden Plover (Pluvialis dominica) Science Article 2 abstract We measured linear dimensions and evaluated identification criteria in Pacific and American Golden-Plovers(Pluvialis fulva and P. dominica) captured for banding. Most of the fulva sampled were wintering birds inHawaii, representative of the mid-Pacific flyway; additional fulva and all dominica were from breeding groundson the Seward Peninsula, […]
Featured Photo: Identification of Adult Pacific and American Golden Plovers in their Southbound Migration
American Golden Plover (Pluvialis dominica) Science Article 6 abstract Connors (1983) and Connors et al. (1993) confirmed that American (Pluvialis dominica) and Pacific (P. fulva) Golden-Plovers breeding in sympatry in Alaska are distinct species, a conclusion adopted by the A.O.U. (1993). Distinguishing these two species requires that the bird’s age or plumage class be determined […]
