- Atlantic Murre, Guillemot (British)
- Guillemot marmette (French)
- Arao común (Spanish)
- In the Atlantic, some populations include "bridled" or "ringed" individuals, which have a white eye-ring and a white line extending backward from the eyes. Bridled birds are more common farther north.
- The high degree of variation in color and markings of Common Murre eggs may allow parent murres to recognize their own egg when they return to the colony from time at sea.
- The egg of a Common Murre is so pointed at one end that when placed on a flat surface and pushed, it rolls around in a circle. Such a shape may help keep the egg from rolling off of its nesting shelf.
Fish, squid and other marine invertebrates.
