- 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.
- Crowd Control.
Stone, Daniel // National Geographic; Jun2014, Vol. 225 Issue 6, p25
The article discusses research on huddling behavior in emperor penguins in the Antarctic by physicist Richard Gerum of the University of Erlangen-Nuremberg in Germany that found when one bird moves, it triggers waves of motion as the others adjust to limit the space between themselves to stay warm.
- 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...
- 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...
