Changes in White Blood Cell Parameters of Common Terns (Sterna hirundo) Exposed to Low Levels of Oil
Ian C. T. Nisbet, Auteur ; Florina S. Tseng, Auteur ; Christine V. Fiorello, Auteur ; Victor Apanius, AuteurLittle is known about sublethal effects on birds of low level exposure to oil. White blood cell parameters (total leukocyte counts and/or differentials) were measured in blood samples from Common Terns (Sterna hirundo; n = 71) exposed to low lev[...]

Ian C. T. Nisbet, Auteur ; David Monticelli, Auteur ; Jeffrey A. Spendelow, Auteur ; Patricia Szczys, AuteurUnequal sex ratios can reduce the productivity of animal populations and are especially prevalent among endangered species. A cohort of 333 Roseate Tern Sterna dougallii chicks at a site where the adult sex ratio was skewed towards females was s[...]
Article
Jeremy J. Hatch, Auteur ; Ian C. T. Nisbet, AuteurManipulation of clutch size during incubation has been used in a number of studies to investigate life-history costs of incubation. We increased or decreased clutches of Common Terns Sterna hirundo during incubation and measured subsequent chick[...]

Andre R. Breton, Auteur ; Ian C. T. Nisbet, Auteur ; Carolyn S. Mostello, Auteur ; Jeremy J. Hatch, AuteurDispersal is increasingly recognized as a process of fundamental importance in population dynamics and other aspects of biology. Concurrently, interest in age-dependent effects on survival, including actuarial senescence, has increased, especial[...]
Article
Anthony J. Gaston, Auteur ; Charles M. Francis, Auteur ; Ian C. T. Nisbet, AuteurUse of soft-metal (aluminum alloy) bands on gulls (Laridae) is known to result in high rates of band loss and, as a result, hard-metal (monel, incoloy, or stainless steel) bands are superior for most studies. However, the U.S. Bird Banding Labor[...]

Ian C. T. Nisbet, Auteur ; David Cabot, Auteur ; Karl Partridge, AuteurSandwich (Thalasseus sandvicensis), Common (Sterna hirundo), and Roseate Terns (S. dougallii) made overland flights from a breeding site in Brittany (northwest France) to forage in a semi-enclosed basin (Rade de Brest) ∼30 km away in 1976 and 19[...]
Article
André Chiaradia, Auteur ; Ian C. T. Nisbet, AuteurWe measured parental care (attendance patterns, foraging trip durations and meal sizes) and chick growth patterns in 45-54 pairs of Little Penguins Eudyptula minor at a breeding colony in southeast Australia during five breeding seasons. Chick s[...]
Article
Ian C. T. Nisbet, Auteur ; Peter Dann, AuteurWe measured breeding performance of little penguins Eudyptula minor at Phillip Island, Victoria, Australia, during a 21-year period. All birds considered in this paper (n=307) were of known age (2-22 y) and sex, and most were of known, or closel[...]
Article
Brian G. Palestis, Auteur ; Ian C. T. Nisbet, Auteur ; Jeremy J. Hatch, Auteur ; Jennifer M. Arnold, Auteur ; Patricia Szczys, AuteurBoth male and female Roseate Terns (Sterna dougallii) have unusually long outer tail feathers, and males tend to have longer tails than females. We examined whether these tail streamers may have evolved as a result of sexual selection, using dat[...]

Jennifer M. Arnold, Auteur ; Darren Sabom, Auteur ; Ian C. T. Nisbet, Auteur ; Jeremy J. Hatch, AuteurAdult Common Terns (Sterna hirundo) reportedly respond to nocturnal predation by deserting colonies from the time of disturbance until dawn the following morning. However, direct evidence for this behavioral response is limited because the noctu[...]
