Contrary to the mistaken opinion that hamsters have poor eyesight, let’s say right away – nature has endowed them with sufficient vigilance for a safe life in the field. This vigilance is far from ideal, but it is supplemented by other sensory organs that help animals to navigate in space, learn about danger and distinguish “their from others”.
But do hamsters see in the dark as well as during the day, or vice versa – their vision is activated only at night, fading in the light of day? Now let’s make it clear.
Boring monochrome or how hamsters see the world
The vision of rodents of different breeds can differ only in the radius of coverage, but its quality remains the same for everyone. For example, the size of the eyes of the Syrian hamster is slightly larger than that of the Dzungarian hamster, so the field of view will be slightly wider with a similar perception of colors and the sharpness of distinguished objects.
Hamsters are short-sighted animals, which prevents them from seeing a clear picture of the world, even at a distance of one meter.
The world through the eyes of a hamster is a blurry outline of objects or moving bodies, among which the animal can only perceive their contours and two shades – yellow and green.
Despite the apparent scarcity of vision, rodents are well adapted for survival. Such a quality of perception for them is the best option, comfortable for a safe existence.
This feature is associated with the way of life of animals that are born in pitch darkness – underground mink, and they spend most of their time in it. Sunlight gives acute discomfort to hamsters. They begin to squint, always trying to avoid direct contact with the source of irritation.
Hunting time: what is the vision for hamsters at night
Rodents are representatives of the nocturnal lifestyle. Most of the daylight hours they rest, starting to be active in the late afternoon. In the dark, the vision of the Dzungarian hamsters (or any other hamsters) becomes more clear and the opportunity to distinguish colors. The perception of rodents is available in the color scheme of yellow-green tones, which helps them get food and hunt.
Orientation in space and the ability to recognize danger to hamsters are provided by the organs of touch, which largely replace their vision:
- vibrissae (or numerous animal whiskers) are located in places with a high concentration of nerve endings, thanks to which it easily scans the surrounding space. This helps the hamster avoid obstacles in its path;
- the hearing developed by the hamsters at a high level allows them to perceive the sound of the world in a conventional and ultrasonic format. This ability allows them to identify unfamiliar sounds at a great distance and have time to hide in case of danger;
- the sense of smell helps the animals to find out where among his brethren are females and where are males. The sharp smell accurately identifies an extraneous smell and, if it smells “hostile,” the hamster tries to avoid contact (in some cases, even with the owners if they stroked the cat).
Life in solid colors is compensated by rodents with a set of useful tools that help them live in safety, get food and find a mink for tens of kilometers.
Therefore, whether hamsters distinguish all the colors of the rainbow or are content with the two main ones, their life does not lose agility and comfort.
