[The eye of birds of prey. Electroretinographic and histologic approach].

Birds are an excellent material for the study of retinal adaptation. In this work, the purpose of the authors is to analyse differences between electroretinograms of species of diurnal habits (Falconiformes) and electroretinograms of species of nocturnal habits (Strigiformes). The same is done on histology material about the two types of retina. The electroretinography answers and the retina histology can be correlated with the different species habits.
