Thermoregulation in Newly Hatched Black-legged Kittiwakes
The development of gull chicks is typically considered semi-precocial, because the birds remain in or near the nest for some days after hatching and depend on parental care, but hatch with downy coverings and possess some thermoregulatory ability (Drent 1967; Palokangas and Hissa 1971; Dawson et al. 1972, 1976; Dunn 1976; Dawson and Bennett 1980. 1981). Newlv hatched chicks of several gull spec...

متن کاملExperimentally reduced corticosterone release promotes early breeding in black-legged kittiwakes.
Breeding at the right time is important for successful reproduction. In birds, stressful environmental conditions are known to delay the timing of breeding but the underlying mechanisms are poorly understood. The stress hormone corticosterone appears to be a good candidate for mediating egg-laying date according to early environmental conditions and physiological state. By experimentally reduci...
متن کاملEarly Spring Wreck of Black-legged Kittiwakes Rissa Tridactyla in North Norway, April 2003
Barrett, R.T., Josefsen, T.D. & Polder, A. 2004. Early spring wreck of Blacklegged Kittiwakes Rissa tridactyla in North Norway, April 2003. Atlantic Seabirds 6(2): 33-45. Large numbers of dead Black-legged Kittiwakes Rissa tridactyla were washed ashore in 'orth 'orway in late April 2003. Inspection of 51 corpses indicated that they had died of starvation. More than 90% of those collected were m...
متن کاملCorticosterone and time-activity budget: an experiment with Black-legged kittiwakes.
In vertebrates, the well established increase in plasma corticosterone in response to food shortage is thought to mediate adjustments of foraging behavior and energy allocation to environmental conditions. However, investigating the functional role of corticosterone is often constrained by the difficulty to track time-activity budget of free-ranging animals. To examine how an experimental incre...
