What if, some birds can unlock their ultraviolet vision super-sense?

Wow. I did not know this.
Some birds have been found to be as intelligent as mammals. And some that can see ultraviolet (UV) light live in a super-sensory world apart, able to transmit and receive signals between each other in a way that is invisible to many other species.

Now the ability of finches, sparrows, and many other birds to see ultraviolet (UV) light is explained in a study published in the journal eLife by scientists at the Washington University School of Medicine in St. Louis.
There are two types of light-sensitive cells, called photoreceptors, in the eye: rods and cones. Cone photoreceptors are responsible for color vision. While humans have blue, green, and red-sensitive cones only, birds have a fourth cone type which is either violet or UV-sensitive, depending on the species,” says senior author Joseph Corbo, MD, PhD, Associate Professor of Pathology and Immunology.
Carotenoid pigments determine bird’s UV perception or not.

News to me too.
It made me think about how birds seem to know in advance when a natural "disaster" of some kind is going to occur. Maybe this "Super Vision" plays a role in that as well.
If I were a researcher, I think I'd look into that possibility.

I'm sensitive to UV light. When I walk into a room with a "Black Light" for posters, I can feel it on my flesh.
It's an uncomfortable feeling.
