Spectral transmission of the ocular media of the pegion (Columba livia).
Spectrophotometric and microspectrophotometric measures of relative spectral transmission were obtained from the cornea, lens, and vitreous body and from the whole eye of young and adult pigeons. Transmission was above 90% throughout the visible spectrum and was maintained at or above 50% into the near-UV at 310 nm. No age-related changes in transmission were found. The results concur with the pigeon's behavioral UV-detection abilities.
