==Feeding and ecology==
The feeding behaviour of auks is often compared to that of penguins;  both groups are [[wing]]-propelled, pursuit divers. In the region where auks live, their only seabird competition are [[cormorant]]s (which are dive-powered by their strong feet). In areas where the two groups feed on the same prey, the auks tend to feed further offshore. Strong-swimming murres hunt faster, schooling fish, whereas auklets take slower-moving krill. Time depth recorders on auks have shown that they can dive as deep as {{Convert|100|m|ft|abbr=on}} in the case of ''Uria'' guillemots, {{Convert|40|m|ft|abbr=on}} for the ''Cepphus'' guillemots and {{Convert|30|m|ft|abbr=on}} for the auklets.
