GULLS and Allies of Africa
Gulls, terns, skimmers, skuas, puffins, and their allies belong to the order Charadriiformes and suborder Lari. In general they take food from the sea. Charadriiformes also contains the sandpipers, plovers and their allies. They are in suborder Charadrii and often feed along the shoreline. It is a matter of debate whether the coursers and pratincoles belong with the gulls or with the sandpipers.
Auks
Order Charadriiformes Suborder Lari Family Alcidae
Auks and their allies (auklets, guillemots, razorbills, puffins) are superficially similar to penguins due to their black-and-white colours, their upright posture and some of their habits. Nevertheless they are not closely related to penguins. Their closest living relatives appear to be the skuas, Auks have to a large extent sacrificed flight, and also mobility on land, in exchange for swimming; their wings are a compromise between the best possible design for diving and the bare minimum needed for flying. The auks are restricted to cooler northern waters. Their ability to spread further south is restricted by their prey hunting method, pursuit diving. This becomes less efficient in warmer waters. The speed at which small fish can swim doubles as the temperature increases from 5°C to 15°C, with no corresponding increase in speed for the bird. Auks live on the open sea and only go ashore for breeding. They vary from 15-45 cm. [abstracted from Wikipedia]
Genus Uria
Guillemot, Common aka Guillemot aka Common Murre Uria aalge Found: north parts of North America, Europe, Asia, Africa
The Common Murre and Thick-billed Murre are similar in appearance. The Common Murre may be brindled, not so for the Thick-billed Murre. The Thick-billed Murre has a white gape stripe, the Common Murre never does.
