The Answer To This Question is . . .From The way a Puffin Looks.

Puffins like to be near the sea, preferably on an open, grassy cliff-top where they can dig their nests. (Yes, dig.) They're found in the north atlantic/arctic ocean. I recently went to see a colony...
Because otherwise there is no need to communicate. If you don't want to communicate, why bother?
