Feathers, eggs, and excreta of Gentoo penguin (Pygoscelis papua ellsworthii), adults, from Livingston Island (South Shetlands), chosen as bioindicators, were used to test the quality of the Antarctic environment. Sex was not examined. The bioaccumulations of toxic trace elements (Cd, Pb, Al, and As), essential trace elements (Fe, Cu, Zn, Mn, Cr, V, Ni, and Sr), and major essential elements (Na, K, Mg, Ca, P, and S) were established. For the first time data about the element contents in Gentoo… 
Humboldt penguins' feathers as bioindicators of metal exposure.
Trace Element Concentrations in Biotic Matrices of Gentoo Penguins (Pygoscelis Papua) and Coastal Soils from Different Locations of the Antarctic Peninsula
The aim of this work is to increase the information on trace metals in seabirds and coastal soils in the Antarctica. Concentrations (mg kg−1 dry weight) of Cd, Cu, Cr, Ni, Mn, Zn and Pb were
Trace elements in feathers and eggshells of brown booby Sula leucogaster in the Marine National Park of Currais Islands, Brazil
Levels of trace elements investigated in feathers and eggshells of brown boobies Sula leucogaster from one bird colony in the Marine National Park of Currais Islands, Brazil, showed no significant difference, but future studies on Paraná coast should focus on the speciation of the elements, especially As, Ni, and Zn, which proved to be a possible problem for the environment and biota.
Assessment of trace metals and porphyrins in excreta of Humboldt penguins (Spheniscus humboldti) in different locations of the northern coast of Chile
The results indicated that penguin colonies from Cachagua Island are more exposed to metal contamination than penguin Colonies from Pan de Azúcar and Chañaral Islands, thus being more likely to develop certain diseases caused by contamination with metals.
Pygoscelis antarcticus feathers as bioindicator of trace element risk in marine environments from Barton Peninsula, 25 de Mayo (King George) Island, Antarctica
Iron, cobalt, and arsenic concentrations in feathers found in this study were the lowest compared to measurements were in several penguin species in Antarctica, confirming to feathers like effective indicators for the trace elements incorporated in the penguins.
Influence of Pygoscelis Penguin Colonies on Cu and Pb Concentrations in Soils on the Ardley Peninsula, Maritime Antarctica
Penguins can bioaccumulate metals, a portion of which can be deposited in the environment through organic remains such as excrement, carcasses, and eggshells. In order to determine Cu and Pb
Metals in Feathers of African Penguins (Spheniscus demersus): Considerations for the Welfare and Management of Seabirds Under Human Care
The concentrations of 15 essential and non-essential metals were investigated in African penguins' feathers from a Northwestern Italian zoological facility, and certain elements reflected the bioaccumulation phenomena that occur through the marine food chain.
Trace elements in feathers of Cape Petrel (Daption capense) from Antarctica
Hg concentration in D. capense is lower than other Procellariiformes which indicate interspecific variations that may be related to their proximity to pollution sources, which can be useful in the environmental monitoring of the trace elements in polar environments.


The penguin feathers as bioindicator of Antarctica environmental state.
Heavy metal accumulations in Adelie penguin, Pygoscelis adeliae, and their variations with the reproductive processes
The concentrations and distribution of heavy metals in the organs and tissues of the Adelie penguin collected around Syowa Station, Antarctica, in 1981 are reported and the changes of heavy metal accumulation with the reproductive activity are discussed.
Mercury and major essential elements in seals, penguins, and other representative fauna of the Antarctic
The results suggest that several control mechanisms operate to maintain physiologically required levels that decreases any effect of heavy metal toxicants such as Hg and Cd.
Mercury, Lead and Copper in Feathers and Excreta of Small Passerine Species in Relation to Foraging Guilds and Age of Feathers
In the present study excreta and feathers of five species of adult passerine birds from Montepulciano wetland were assayed for trace elements between January and August 2006 and copper levels were found to be high mainly in insectivorous birds.

Mercury and other metals in eggs and feathers of glaucous-winged gulls (Larus glaucescens) in the Aleutians
The levels of most metals in feathers are below those known to be associated with adverse effects in the gulls or their predators, however, levels of mercury in some gull eggs are within a range suggesting that several eggs should not be eaten in one day by sensitive humans.
Can Excrement and Feathers of Nestling Songbirds Be Used as Biomonitors for Heavy Metal Pollution?
It is concluded that excrement of great and blue tit nestlings can be used as a biomonitor for heavy metals (lead, cadmium, arsenic, and copper), whereas feathers appear only to be suitable for lead pollution.
Spatial Patterns in a Bioindicator: Heavy Metal and Selenium Concentration in Eggs of Herring Gulls (Larus argentatus) in the New York Bight

Herring gull egg contents can be used to monitor metal concentrations at nearby colonies to indicate areas of concern for particular metals, and may confirm suspected associations or identify hitherto unsuspected problems.
Amino acid composition of feather barbs and rachises in three species of pygoscelid penguins : nutritional implications
The composition of contour feathers of three species of penguins, Pygoscelis adeliae, P. antarctica, and P. papua, showed a large mismatch between nonkeratinous mixed tissue proteins and feathers that could result in highly inefficient reutilization of tissue amino acids in feather synthesis during the molt fast.
