Night diving by some emperor penguins during the winter breeding period at Cape Washington
Evidence is obtained that some birds may feed before the egg is laid, and if they do, and some are males, then their fast is much less than 115 days, which is a better chance of completing the 65 day incubation fast and success in fledging the chick.
Energy saving processes in huddling emperor penguins: from experiments to theory
These processes, linked together, explain how huddling emperors save energy and maintain a constant body temperature, which ensures a successful incubation in the midst of the austral winter.
One for all and all for one: the energetic benefits of huddling in endotherms
This is the first attempt to review the various implications of this widely used behavioural strategy, huddling, in animals faced with high heat loss due to a high surface‐to‐volume ratio, poor insulation, or living in cold environments.
Body temperature changes induced by huddling in breeding male emperor penguins.
The first data on body temperature changes throughout the breeding cycle of emperor penguins is presented, suggesting that the energy savings of huddling birds is due to a metabolic depression, the extent of which depends on a reduction of body surface areas exposed to cold.
How do weather conditions affect the huddling behaviour of emperor penguins?
The first investigation into the effects of changes in wind speed and ambient temperature on different components of penguin huddling behaviour is reported, finding that emperor penguins complex huddled behaviour was modulated differently depending on these two parameters.
Huddling behavior in emperor penguins: Dynamics of huddling
This complex social behavior enables all breeders to get a regular and equal access to an environment which allows them to save energy and successfully incubate their eggs during the Antarctic winter.
Aptenodytes Forsteri Optimization: Algorithm and applications
Collective self-optimization of communicating active particles
The proposed optimal field–based collective interactions represent a generic concept at the interface of active matter physics, collective behavior, and microbiological chemotaxis which might serve as a useful ingredient to optimize ensembles of synthetic active agents or to help unveil aspects of the communication rules which certain social groups use to maximize their survival chances.
Social interaction and the thermogenic response of chicken hatchlings
Social interaction without physical contact decreased the thermogenic response to cold as much as huddling did, Presumably, during the cold exposure, social interaction lowered the additional energetic cost of the stress of isolation.
Aggregation behavior of juvenile Neptunea cumingii and effects on seed production
The results broaden the understanding of gastropod aggregation behavior and can be used to develop and improve commercial breeding strategies and resource recovery for N. cumingii.

It is suggested that IMR within the thermoneutral zone might be close to basal MR in most antarctic and sub-antarctic sea birds.
Energy expenditure for thermoregulation and locomotion in emperor penguins.
The data suggest that walking 200 km (from the sea to the rookery and back) requires less than 15% of the energy reserves of a breeding male emperor penguin initially weighing 35 kg.

Thermoregulation in fasting emperor penguins under natural conditions.
Emperor penguins breed during the cold antarctic winter; the males incubate the single egg while fasting for up to 4 mo and losing some 20 kg of their body mass, higher than predicted from general metabolic equations for birds.
Animal Physiology: Adaptation and Environment
This chapter discusses the regulation of movement, muscle, biomechanics, and information and senses in the body during the menstrual cycle and the role that food and energy play in this process.
