[The physiologic electroretinogram of the raptor bird--clinical and theoretical aspects]

A method of electroretinography applicable to birds is described in this paper by the example of common buzzard (Buteo buteo L.). Electroretinograms (ERG) under dark and bright adaptation as well as flicker ERGs were recorded from 15 common buzzards, and normograms were established. Methodological reliability was verified by a tenfold test on one animal. The results are compared with ERG findings from dog and are discussed with reference to behaviour physiology and clinical diagnosis.
