In 2000–2001 juvenile individuals of black-headed gull (Larus ridibundus) were repeatedly found in a Nadeje fishpond system in the Trebon Basin Area that were incapable of flying, with deformed wings. The investigation proved the rotation of metacarpal bones and luxation of the carpal joint. The Roentgen photograph did not show any consequences of any fracture, but this was evidently a post-traumatic state. A possible explanation is traumatisation of developing wings in young birds that got stuck by their wings in viscous mud around the nest colony.Keywords:
