Primary source abstract: "The foveas of nine avian species, initially selected for the presence of a deep fovea and representing a wide range of eye sizes and ecological habits, were studied with quantitative light microscope techniques." |

P.180 left column 3rd paragraph: "In the American kestrel, for example, the number of receptors per visual degree is 8,300 in the central and 7,700 in the temporal fovea, and the ganglion cell number per visual degree is 3,000 in the central and 700 in the temporal fovea (primary source)." |
