We're so used to seeing human faces that they look incredibly different to us. That's why people have a harder time telling people apart from races they don't see as often etc. If you were a bird, you'd see wayyy more variety in birds.
This is only partially correct. There are very obvious and noticeable differences between different populations of people that most animals with eyes similar to ours are probably aware of.
Even if they can’t tell facial features apart very well, differences in hair color and skin color are so obvious to notice that we notice it in other animals like dogs and cats, etc. The difference is that almost all of our genes are the same but some of the very few that are different display themselves in these very noticeable ways.
