Bird visual ecology
Although all bird eyes share the same basic features, we expect specific adaptations to the ecology – for instance in seabirds, night-active birds and raptors – but such adaptations have rarely been studied.
- how the bird cone mosaic and ganglion cell density relate to behavioural spatial resolution of chromatic and achromatic stimuli
- how the eyes of nocturnal birds such as owls and nightjars are adapted to their nocutrnal lifestyle
- how good birds really can discriminate colours, and how well they can do this in changngling light environments
- how seabird eyes are adapted to a life at sea
- how well birds can see stationary and moving contrast patterns
and some other questions. Our pet birds are budgerigars and chickens, but we have looked at a large range of birds. Students with interest in birds and bird vision are welcome!
