Polymelia and polydactyly in White Stork (Ciconia ciconia)
We report polymelia and polydactyly in an immature White Stork (Ciconia ciconia). Polymelia and polydactyly are unusual leg malformations and have been rarely recorded in birds. To our knowledge there is no study indicating the two cases observed in the same bird. We observed a White Stork which has two pairs of fused legs, with a total of nine and 10 toes on left and right fused legs respectiv...
متن کاملExtra-pair paternity in the socially monogamous white stork (Ciconia ciconia) is fairly common and independent of local density
Although many birds are socially monogamous, most (>75%) studied species are not strictly genetically monogamous, especially under high breeding density. We used molecular tools to reevaluate the reproductive strategy of the socially monogamous white stork (Ciconia ciconia) and examined local density effects. DNA samples of nestlings (Germany, Spain) were genotyped and assigned relationships us...
متن کاملSkeletal pathology in white storks (Ciconia ciconia) associated with heavy metal contamination in southwestern Spain.
In 1998, a mine tailings dyke in southwestern Spain broke, flooding the Agrio-Guadiamar river system with acid tailings up to the borders of one of the largest breeding colonies of white storks in the western Palearctic, Dehesa de Abajo. Over the following years, a high proportion of nestlings developed leg defects, prompting this study. Ten fledglings with leg deformities from the spill area w...
متن کاملDisrupted bone metabolism in contaminant-exposed white storks (Ciconia ciconia) in southwestern Spain.
In 1998, the Aznalcóllar mine tailings dyke in southwestern Spain broke, flooding the Agrio-Guadiamar river system with acid tailings up to the borders of one of the largest breeding colonies of white storks in the western Palearctic, Dehesa de Abajo. Over the following years, a high proportion of nestlings developed leg defects not seen before the spill, prompting this study. Nestlings with de...
متن کاملMercury in white stork (Ciconia ciconia) chick feathers from northeastern Mediterranean areas in relation to age, brood size, and hatching order.
Mercury (Hg) levels in white stork (Ciconia ciconia) feathers collected in the mid-1990s from five northeastern Mediterranean (Greece) areas varied, with mean ranges between 301 ng g(-1) dry weight (dw) (Pinios River) and 1911 ng g(-1) dw (Sperchios Delta). A significant increase of Hg levels in chick feathers with age (surrogated by bill size) was found in the Evros and Pinios River areas, a n...
