Some antelope remain in small areas throughout the year, but many species undertake seasonal movements over a large range.
Because of that, in Sakha, snow sheep undertake seasonal movements of 80 120 km (50 70 miles) to winter on the southern or eastern slopes of mountains, while in Kamchatka migrations of over 50 km (30 miles) have been documented.
Whitetip reef sharks generally remain within a highly localized area; only rarely do they undertake long movements, wandering for a while before settling down somewhere new.
Many species, such as dunlin Calidris alpina and western sandpiper Calidris mauri, undertake long movements from their Arctic breeding grounds to warmer locations in the same hemisphere, but others such as semipalmated sandpiper C. pusilla travel longer distances to the tropics in the Southern Hemisphere.
However this assumption is invalid for species that undertake large movements to find suitable conditions because of vast temporal fluctuation in conditions [41].
Sedentary species may undertake local movements in response to weather events [14], and their distribution might be limited by climatic extremes [10], two factors that are better accounted for with weather models than climate.
However, they do not migrate out of Australia in large numbers, although they do undertake intracontinental movements and occupy the same habitats as migratory shorebirds.
Some moths display vertical take-off flight, which carries them above the flight boundary layer and allows them to undertake migratory movement in upper wind systems.
Without a goat's strong front legs and flexible musculature, a person undertaking goatlike movements, such as galloping or leaping to the ground head first, would be badly hurt.
The dusky shark is nomadic and strongly migratory, undertaking recorded movements of up to 3800 km; adults generally move longer distances than juveniles.
