Diet:

  • Binturongs are omnivores with a diet that includes fruits, leaves, small mammals, birds, and eggs.
  • They have a keen sense of smell, which they use to locate food in their forest habitat.

Conservation Status:

  • The binturong is currently classified as "Vulnerable" on the International Union for Conservation of Nature (IUCN) Red List.
  • Threats to their population include habitat loss due to deforestation and the pet trade.

Significance in Kaziranga National Park:

  • The recent addition of binturongs to Kaziranga National Park and Tiger Reserve in Assam highlights the park's biodiversity.
  • As a Schedule I species under the Wildlife Protection Act of 1972, efforts are likely in place to ensure their protection and conservation in this region.

Small-Clawed Otter

Physical Characteristics:

  • The small-clawed otter is the smallest otter species, with a slender and streamlined body.
  • It has short, sleek fur that is usually dark brown on the back and lighter on the underside.

Communication:

  • Small-clawed otters are vocal animals, using a variety of sounds, including whistles, chirps, and squeaks, to communicate with each other.

Conservation Status:

  • The small-clawed otter is listed as "Vulnerable" on the International Union for Conservation of Nature (IUCN) Red List.
  • Threats include habitat loss, pollution, and illegal wildlife trade.

Significance in Kaziranga National Park:

  • The recent addition of small-clawed otters to Kaziranga National Park and Tiger Reserve in Assam highlights the park's commitment to biodiversity conservation.
  • Being designated under Schedule I of the Wildlife Protection Act of 1972 emphasizes the need for protective measures to ensure their survival in this region.

Reproduction:

  • Small-clawed otters have a monogamous mating system, forming long-term pair bonds.
  • They build nests using vegetation, and both parents are involved in raising the offspring.

PRACTICE QUESTION

Q. Consider the following statements:

1.Kaziranga National Park is situated on the banks of the Subansiri River.

2.Binturongs are primarily ground-dwelling mammals, rarely venturing into trees.

3.The Small-Clawed Otter is the largest otter species.

How many of the above statements are correct?

A)      Only 1

B)      Only 2

C)      All

D)      None
