The confusion hypothesis states that the stripes confuse predators, be it by: making it harder to distinguish individuals in a group as well as determining the number of zebras in a group; making it difficult to determine an individual's outline when the group runs away; reducing a predator's ability to keep track of a target during a chase ...
Circadian migration is where birds utilise circadian rhythm (CR) to regulate migration in both fall and spring. In circadian migration, clocks of both circadian (daily) and circannual (annual) patterns are used to determine the birds' orientation in both time and space as they migrate from one destination to the next.
Zebras have a less efficient digestive system than ruminants but food passage is twice as fast. [15] Thus, zebras are less selective in foraging, but they do spend much time eating. The zebra is a pioneer grazer and prepares the way for more specialised grazers such as blue wildebeests and Thomson's gazelles. [9] Lions feeding on a zebra
The zebras were being transported from Washington to Montana when the driver took the Interstate 90 exit for North Bend, located about 30 miles (48 kilometers) southeast of Seattle, to secure the ...
A "lost" continent that once connected Asia to southern Europe may have formed an ancient passageway that helped animals migrate west, according to new research. Scientists hunt for remains of ...
Many hummingbird species migrate north in late winter and spring after spending the cold winters in Central America or Mexico. According to the American Bird Conservancy, some hummingbirds travel ...
Mountain zebras live in hot, dry, rocky, mountainous and hilly habitats. They prefer slopes and plateaus as high as 2,000 m (6,600 ft) above sea level, although they do migrate lower during winter. Their preferred diet is tufted grass, but in times of shortage, they browse, eating bark, twigs, leaves, buds, fruit, and roots. They drink every day.
Zebras appear to be a monophyletic lineage [10] [11] [12] and recent (2013) phylogenies have placed Grévy's zebra in a sister taxon with the plains zebra. [10] In areas where Grévy's zebras are sympatric with plains zebras, the two may gather in same herds [13] and fertile hybrids do occur. [14]
