... also contribute to the olfactory landscape and may act as an orienting map. To test sensitivities to a colony scent we studied whether King penguins ( Aptenodytes patagonicus ) could detect the smell of sand, feathers or feces by holding presentations beneath their beaks while they naturally slept...

...Anna P. Nesterova; Jules Chiffard; Charline Couchoux; Francesco Bonadonna SUMMARY King penguins ( Aptenodytes patagonicus ) live in large and densely populated colonies, where navigation can be challenging because of the presence of many conspecifics that could obstruct locally available cues. Our...

... is limited. To address this trade-off we investigated muscle maturation in both the pectoral and pelvic girdles of king penguin chicks. This species has an exceptionally long rearing period (1 year), which is prolonged when parental food provisioning is drastically reduced during the sub-Antarctic winter...

... of mouth parts (recorded with a Hall sensor). In the present study, we used these three techniques to compare their validity and obtain information about the feeding activity of two free-ranging king penguins ( Aptenodytes patagonicus ). Crucially, and for the first time, two types of beak-opening events...

... orientation in King Penguin ( Aptenodytes patagonicus )chicks that live in a large and densely populated colony. The two main objectives were to determine whether chicks displaced to a novel location away from the colony (i) can orient towards the colony and return to their crèche and (ii) rely on visual...

...Thierry Aubin; Pierre Jouventin SUMMARY King penguin chicks identify their parents by an acoustic signal, the display call. This call consists of a succession of similar syllables. Each syllable has two harmonic series, strongly modulated in frequency and amplitude, with added beats of varying...

... of this study was to determine whether a decrease in non-esterified fatty acid (NEFA) release from adipose tissue could be a component of this signal. Lipolytic fluxes and primary triacylglycerol:fatty acid (TAG:FA) cycling were determined in vivo in breeding, fasting king penguins ( Aptenodytes patagonicus...

Flipper beating stopped during the latter part of ascent: at 29±9 % (mean ± S.D.) of dive depth(mean dive depth=136.8±145.1 m, N =425 dives) in king penguins,and at 52±20 % of dive depth (mean dive depth=72.9±70.5 m...
