    TOPOGRAPHY AND MORPHOLOGY OF RETINAL GANGLION-CELLS IN FALCONIFORMS - A STUDY ON PREDATORY AND CARRION-EATING BIRDS
    (WILEY-LISS, 1991) INZUNZA, O; BRAVO, H; SMITH, RL; ANGEL, M
    The topographic distribution of retinal ganglion cells and their cell body size have been studied in five Falconiform species, including predatory (chilean eagle Buteo fuscenses australis, and sparrow hawk Falco sparverius) and carrion-eating (chimango caracara Milvago chimango; condor Vultur gryphus, and black vulture Coragyps atratus) birds. All these species had a well defined nasal fovea and a horizontal streak. Instead of a temporal fovea as in eagles and hawks, an afoveate temporal area is present in chimango, condor, and vulture. The highest ganglion cell density was found in the nasal fovea of Falco and Buteo with 65,000 and 62,000 cells/mm2, respectively.
