“…Copper Approximately twice the concentration of Cu was detected in the livers of male ducks as in the livers of female ducks in all dosed groups (Table 11). Hanson and Jones (1974) found significantly higher concentrations of Cu in the feathers of female Ross' geese (Anser rossii) than in males.…”

Toxicity of Ingested Bismuth Alloy Shot in Game-farm Mallards

et al. 1997

In a 30-day study involving penned game-farm mallards (Anas platyrhynchos), no harmful health effects were detected from dosing with either six, No. 4, bismuth/tin (Bi/Sn) alloy shot or six, No. 4, steel (Fe) shot, as compared with sham (0 shot) dosing. Survival, hematocrit (Hct) values, body weight, and mean weights of kidneys, livers, gonads, and gizzards were not affected. Mean concentrations of nutritionally essential elements (calcium [Ca], phosphorous [P], magnesium [Mg], zinc [Zn], copper [Cu], Fe, and Sn) were different among doses and between sexes in kidneys, livers, and gonads. However, concentrations of these elements in these organs and tissues in Bi-dosed ducks were not different from both 0- and Fe-dosed ducks. Bi/Sn alloy shot, as tested in this study, elicited no indications of toxicity in game-farm mallard ducks.

“…Variability between individuals of the same species is much more complex than within‐individuals and can be confounded with the effect of many variables that are intrinsic to the individual, such as age (Szép et al 2009, Mansouri et al 2015, Óvári et al 2018), sex (Hanson and Jones 1974, Bortolotti et al 1990, Óvári et al 2018), or even diet which can vary between habitats (Kelsall and Burton 1979, Bortolotti and Barlow 1988). Several studies have reported high variability in the mercury concentration of individuals for several seabird species (Furness et al 1986, Bond and Diamond 2008), but there is little information available on other elements or taxa.…”

Intra‐ and interspecific variation in trace element concentrations in feathers of north European trans‐African migrants

The knowledge of migratory connectivity is important for understanding the potential drivers of populations and it is thus important for conservation implications. Migratory connectivity of species can be studied using exogenous, such as rings and transmitters, or endogenous markers, such as stable isotopes and trace elements. The use of trace elements has been much less frequently studied compared to stable isotopes. Trace elements can be studied from the feathers of birds and this does not necessarily require trapping of individuals. Here we studied the variation of 18 different trace elements in feathers of two long‐distance trans‐African migrants, willow warblers Phylloscopus trochilus and barn swallows Hirundo rustica, using body feathers of museum specimens of birds from Finnish breeding grounds. The trace elements were measured using laser‐ablation inductively‐coupled‐plasma mass‐spectrometry (LA‐ICP‐MS). We show that trace element concentrations were relatively stable along the rachis within the same feather except in Ni and S, which showed a quadratic pattern. In general, variation within feathers of the same individuals was smaller than in feathers between individuals for most elements. Furthermore, concentrations of 11 trace elements showed significantly higher concentrations in willow warbler feathers collected in spring than in autumn, moulted in African wintering grounds and European breeding grounds, respectively. Last, concentrations of seven trace elements were significantly higher in the spring feathers of willow warblers compared to barn swallows. This suggests that trace elements could be used to separate moulting grounds of the birds on the larger scale within the same species, but also sampling design should be carefully considered.

“…It seems axiomatic that each set of flight feathers will, to some degree, reflect the chemistry of the particular area in which it was grown. Some preliminary success in identifying the origins of birds by chemical means have been reported ( Hanson andJones 1968: Devine andPetede 1968).…”

KELSALL, J. P., and W. J. PANNEKOEK. 1976. The mineral profile of plumage in captive lesser snow geese. Can. J. This is a contribution to a larger study aimed at development of a technique to determine the origins of waterfowl from their feather chemistry. Results are reported of an experiment designed to show whether there were differences in the mineral profile between primary feathers one-half to two-thirds grown and fully formed feathers, within a population of captive lesser snow geese. Primaries 1 and 10 were used as sample materials and the elements Na, Ca, K, Fe, Cu, Mn, Mg, Zn, and Si were used as variables. Statistically significant differences were shown between stages of growth in respect to all variables except Cu and Zn. The experiment also showed significant differences between different primary feathers in respect to all variables, and some differences attributable to the sex of birds from which samples were taken.
