Reindeer UPSC NOTE

 Why in News

  • Researchers have discovered that the more time reindeer spend ruminating, the less time they spend in non-rapid eye movement (non-REM) sleep. 

  • EEG recordings revealed that reindeer’s brainwaves during rumination resemble the brain waves present during non-REM sleep.

  • These brainwave patterns suggest that the reindeer are more “rested” after ruminating.

  • The researchers speculate that this multitasking might help reindeer get enough sleep during the summer months.

  • When food is abundant and reindeer feed almost 24/7. 

  • The results were published on December 22 in the journal Current Biology.


  • Common Name: Sangai, Brow antlered deer, Dancing Deer

  • Scientific Name: Rucervus eldii

  • The brow-antlered deer, or sangai, is the state animal of Manipur.

    • The animal’s coat is a dark reddish brown during winter months and it becomes a much lighter shade in summer.

  • Native to Cambodia, China, India, Laos and Myanmar, these animals were earlier spread widely across habitats in south and south-east Asia.

  • The deer’s habitat has varied from shrubland and grassland to dry forests and marshland, depending on the country they’re found in.

  • In India, these animals are found only in Manipur’s famed Loktak lake.

  • While globally habitat loss has been a grave concern in the conservation of this deer, hunting is an additional threat in Manipur.

  • While the habitats have been encroached for grazing, cultivation, and fish farming, the animals are highly threatened by a hydro-electric project in the lake.
