Abstract In seabirds, colors of feathers and external tissues have only recently been studied, and ultraviolet (UV) color has not yet been detected. Using live individuals as well as museum skins, we found UV peaks of reflectance in two large Aptenodytes species, King (A. patagonicus) and Emperor (A. forsteri) Penguins. UV reflectance did not occur on the feathers, claws, or skin of these species, nor did we find UV reflectance in five other genera of penguins (11 species). UV peaks overlapped… 

Sexual selection, social selection and individual quality : underlying mechanisms and ultimate consequences of ornamentation in a monomorphic species, the King penguin (Aptenodytes patagonicus)

TLDR
The king penguin is a monomorphic bird species and an outstanding model to study ornament evolution, and results show that those ornaments are partly condition-dependent, and reliable traits that may be used to assess the quality of a potential sexual partner, implying that their evolution and maintenance is partly determined by sexual selection.

Mutually honest? Physiological ‘qualities’ signalled by colour ornaments in monomorphic king penguins

TLDR
Over an exhaustive set of physiological variables, several suggestive patterns indicated the conveyance of honest information about mate quality in this monomorphic species, however, sex-specific patterns suggested that monomorphic ornaments may signal different information concerning body mass and oxidative balance of males and females, at least in king penguins.

The best dressed are less stressed: associations between colouration and body condition in a North American owl

TLDR
Facial white, but not eye colour, was a robust predictor of short- and long-term body condition, permitting detection of individuals in the best and most consistent condition.

Beak colouration as a possible sexual ornament in gentoo penguins: sexual dichromatism and relationship to body condition

TLDR
The results suggest that the red colour of the beak spot has the potential to be a secondary sexual character in males, and experimental manipulation of beak colouration will be needed to ascertain the role of this trait.

"YELLOW SPOT"—A NEW TRAIT OF GENTOO PENGUINS PYGOSCELIS PAPUA ELLSWORTHII IN ANTARCTICA

Colour patterns of terrestrial birds have been well studied, but relatively less is known about seabird coloration (Jones & Hunter 1993, Jouventin et al. 2005). Among the six genera belonging to

Is there any proof of UV-sensitivity and its role in king penguins (Aptenodytes patagonicus)?

TLDR
It is argued that based solely on the microspectrophotometric analysis of two Humboldt penguin retinae, without electrophysiological spectral sensitivity measurements and spectral transmission records for the dioptric structures, there is no hard evidence for UVvision in king penguins.

Ornamental colors reveal age in the king penguin

TLDR
The results suggest that head ornaments in king penguins could signal sexual maturity or social status, and no sex differences were found in the intensity of colored ornament, which can result from mutual mate choice or genetic correlation between sexes.

Brighter is better: bill fluorescence increases social attraction in a colonial seabird and reveals a potential link with foraging.

TLDR
The bill pigment is unique in the Genus Aethia, and its spectra did not match any known molecule, and it occurred in two phenotypes that may differ geographically, perhaps due to environmental heterogeneity.

How king penguins advertise their sexual maturity

Glowing in the light: fluorescence of bill plates in the Crested Auklet (Aethia cristatella)

TLDR
Differences in ornamentation and fluorescence may be related to life-history strategies associated with sexual selection and predator avoidance in auklet species.

Synchronous Underwater Foraging Behavior in Penguins

TLDR
Electronic time-depth recorders used to examine the synchronous foraging behavior of penguins both at the surface and underwater indicate that the penguins were visually in contact during the dives and suggests a coordinated underwater behavior to search and catch prey.

TLDR
The first example of nearly pure UV colouration in passerines, the Asian whistling-thrushes (Myiophonus spp.), is presented and the barb-born UV-structure seems to be a modification of the taxonomically widespread ‘spongy structure’ producing blue and violet feather colours.

Diving Behavior of Emperor Penguins Nurturing Chicks at Coulman Island, Antarctica

TLDR
Although few in number, occurrence of dives > 450 m appeared consistently during the commute of every bird and suggests some important but unknown function, it is proposed that such dives may not occur during the austral winter night.

Behavioural and physiological effects of absence of ultraviolet wavelengths on European starlings Sturnus vulgaris

TLDR
Stress effects of UV-deficient lighting appear small relative to the overall impact of captivity, but may nevertheless become apparent after the initial effects of capture subside.

Ultraviolet plumage ornamentation affects social mate choice and sperm competition in bluethroats (Aves: Luscinia s. svecica): a field experiment

TLDR
This work reports the first experimental evidence that UV signalling influences male mating success in free–ranging birds, and concludes that the treatment affected both social and extra–pair mate choice.

Individual color variation and male quality in pied flycatchers (Ficedula hypoleuca): a role of ultraviolet reflectance

TLDR
The results suggest that in pied flycatcher males, the UV reflectance of plumage may be positively correlated with individual quality.

On the measurement and classification of colour in studies of animal colour patterns

TLDR
New methods make it practical to measure the colour spectrum of pattern elements (patches) of animals and their visual backgrounds for the conditions under which patch spectra reach the conspecific's, predator's or prey's eyes.

Diving Behavior and Energetics During Foraging Cycles in King Penguins

TLDR
It was concluded that deep—diving, for unknown reasons, is an important component of foraging success, and diving capacities of King Penguins are remarkable compared to other birds and many pinnipeds, and calculated foraging energetics can be closely estimated from time—energy budgets.
