TL;DR: Investigation of daily variations of blood chemistry during the 1990-91 Antarctic smnmer solstice in six adult chinstrap penguins in the absence of eat-fast cycles found that the daily cycle of light intensity is the most likely timekeeper for circadian rhythms in blood parameters of chinstrape penguins.

TL;DR: Results suggest that well nourished females produce more numerous and better nourished nestlings, with the largest and earliest broods being better nourishing.
Abstract: The relationship between clutch-size, brood-size and nutritional condition in Imperial Eagle nestlings in Donana National Park (southwest Spain) was studied during 1986–¸88 Urea and uric acid level in blood were used to determine nutritional condition Clutch-size, brood-size and hatching date were closely related to the physiological condition of nestlings, with the largest and earliest broods being better nourished Sex and size order in the brood had no significant effect on nestling nutritional condition These results suggest that well nourished females produce more numerous and better nourished nestlings
