21. These studies are generally directed to the altitudinal shifts in forest species on mountains. 22. The Scots pine reaches its altitudinal limit about 200 m lower than the mountain birch. 23. Although resident in many areas, they may make altitudinal movements in response to rains. 24. The sightings cover a fairly wide altitudinal range, from sea level to 2000 m. 25. Its altitudinal range on Mount Tahan is known to extend from 800 to 1350 m. 26. It is apparently a resident bird; there is no indication even for altitudinal migrations. 27. Temperate bat species are also altitudinal migrants. 28. Over 30 % of birds and other species in montane forests show altitudinal migration patterns. 29. Shorter migrations are common, including altitudinal migrations on mountains such as the Andes and Himalayas. 30. Altitudinal migration is common on mountains worldwide, such as in the Himalayas and the Andes.
