The Least Auklet, as its name implies, is the smallest of the North American alcids (upright penguin-like birds).
Here is one photographed on St. Paul Island, Alaska, in June of this year.
This small bird is not only cute, it has cute names in other languages!
French: Starique minuscule.
Unangan (Aleut): Chuuchii.
