When temperatures start to dip toward late autumn, these cervids begin the long return journey to their more southern ranges, where food remains plentiful throughout the winter.<\/p>\n<p>Although some terrestrial animals can perform longer migrations, a 2019 study published in <em>Scientific Reports<\/em> revealed that the round-trip distance for <em>Rangifer tarandus<\/em> averaged about 1,200 kilometers in a straight line.<\/p>\n<p>This represents the largest distance ever documented for a species closely tracked throughout its migratory routine.

Driven by the pursuit of cervid herds, the packs in Alaska and the Yukon can cover about 5,630 kilometers within twelve months.<\/p>\n<p>As impressive as these distances are, they pale in comparison with those covered by certain bird species.<\/p>\n<p>In terms of nonstop migration, it is the red knot that takes the top spot, with a four-month-old individual covering 13,560 kilometers between Alaska and Tasmania in just 11 days.
