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 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 کاملProlonged Incubation and Early Clutch Reduction of White Storks (Ciconia ciconia)
—Two cases of prolonged incubation by White Storks (Ciconia ciconia) were observed in the same nest in 2009 and 2010 in southwest Poland. Incubation lasted at least 59 and 65 days, respectively; i.e., 84 and 103% longer than the average incubation period. Extended incubation was accompanied by other abnormal breeding behavior. The lack of observed copulation in either breeding season, an extrem...
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 کاملThe turnover of White Storks Ciconia ciconia on nests during spring migration
It is widely accepted that the first White Storks to arrive at a nest remain there to breed. In contrast to this belief, the paper describes the replacement of at least three males and at least one female at one nest in SW Poland during the spring of 1994. The first pair occupied the nest for 5–8 days, the second pair for one day, and probably only the third pair remained at the nest to actuall...
