Can swallows see in the dark?

Swallows, like many bird species, have good eyesight adapted for their active lifestyle, particularly during the day. They are diurnal, meaning they are primarily active during daylight hours, and their vision is optimized for seeing in bright light rather than low-light conditions. While they may have some ability to see in dim light, they are not nocturnal birds and do not have the adaptations necessary for effective night vision.
