Vision and visual perception is indispensable for birds, while the necessity for fully functional vision is bound to the specific living and keeping conditions. Fully functional vision is vital for rehabilitation and survival in the wild, for commercial poultry to survive in the flock. For raptors multiple aspects such as diurnal vs. nocturnal species, living in the wild vs. falconry keeping, one eye vs. two eye sight have to be considered and interpretated. For pet birds, visual impairment or even total blindness may not be an indication for euthanasia.
Based on initial outlines how to clinically determine avian sight, the round table discussion will focus on drawing a practical orientated decision guideline for the interpretation and consequences of vision and visual impairment in birds considering specific species and living conditions.
