About Kaziranga national park 

  • Kaziranga, home of the world’s most one-horned rhinos, has 96 speciesof wetland birds , one of the highest for wildlife preserves in India.
  • Much of the focus of conservation efforts in Kaziranga are focused on the ‘big four’ species— rhino, elephant, Royal Bengal tiger and Asiatic water buffalo.
  • The park also has more than 250 seasonal water bodies, besides the Dipholu River running through it.

Importance of wetland for the water bird population

  • Some birds depend on wetlands almost totally for breeding, nesting, feeding, or shelter during their breeding cycles. 
  • Birds that need functional access to a wetland or wetland products during their life cycle, especially during the breeding season, can be called “wetland dependent”
  • Other birds use wetlands only for some of their needs, or they might use both wetland and upland habitats.

Number of birds in a wetland depends on:

  • Number of wetlands in the area
  • Wetlands’ size and water depth
  • Climate 
  • Species of bird and the bird’s adaptations to wetlands.

Significance:

Data on avian wealth is important because the wetlands nourish Kaziranga’s ecosystem. Increase or decrease in the number of birds is indicative of the park’s health.
