Examines the behavior of foraging emperor penguin in the western Ross Sea, Antarctica. Distribution of foraging birds from four colonies; Use of time-depth and satellite transmitters in getting foraging and distribution data; General foraging patterns of birds; Range of diving depths.
- Why Emperors huddle.
Hickey, Georgina; McG, K. // Nature Australia; Winter98, Vol. 26 Issue 1, p16
Presents information on a metabolic study conducted by Andre Ancel from the National Center for Scientific Research in France, which investigated why Emperor Penguins (Aptenodytes forsteri) huddle. Information on the male Emperor Penguin during the breeding season; How the study was conducted;...

- PENGUINS DO THE HUDDLE.
Dutton, Gail // National Wildlife (World Edition); Oct/Nov2011, Vol. 49 Issue 6, p10
The article reports on research by Antarctic scientist Daniel Zitterbart on the huddling behavior of male emperor penguins as they incubate eggs during winter breeding season, finding coordinated movements among the birds thought to benefit blood circulation and concentrate their body warmth.
- HUDDLE UP!
Dutton, Gail // Cobblestone; Feb2014, Vol. 35 Issue 2, p50
The article discusses the behavior of animals who use cooperate and help each other, with information on the sharing of food by vampire bats, female mule deer's protection of fawns, and the gathering of emperor penguin's to stay warm by sharing body heat.
- Extreme dives by free-ranging emperor penguins.
Wienecke, Barbara; Robertson, Graham; Kirkwood, Roger; Lawton, Kieran // Polar Biology; Feb2007, Vol. 30 Issue 2, p133
We examined the incidence of extreme diving in a 3-year overwintering study of emperor penguins Aptenodytes forsteri in East Antarctica. We defined extreme dives as very deep (> 400 m) and/or very long (> 12 min). Of 137364 dives recorded by 93 penguins 264 dives reached depths > 400 m and 48...
- Non-consumptive factors affecting foraging patterns in Antarctic penguins: a review and synthesis.
Ainley, David; Ballard, Grant // Polar Biology; Jan2012, Vol. 35 Issue 1, p1
Recent research has clearly shown that the fear of predation, i.e. aversion to taking risks, among mesopredators or grazers, and not merely flight from an apex predator to avoid predation, is an important aspect of ecosystem structuring. In only a few, though well-documented cases, however, has...
