STATE OF INDIA'S BIRDS (SoIB)

STATE OF INDIA'S BIRDS (SoIB)

 
 
 
1. Context
A large number of bird species in India are either currently declining or projected to decline in the long term, according to a report based on data from about 30,000 birdwatchers that was released on Friday (August 25). Out of the 942 bird species that were assessed, 142 are diminishing and only 28 are increasing
2. Bird Species in India
India is home to a diverse range of bird species due to its varied landscapes, climate, and ecosystems
India is home to a diverse range of bird species, with over 1,350 recorded

here are some notable bird species found in India:

  1. Indian Peafowl: The national bird of India, known for its vibrant and iridescent plumage.

  2. Indian Roller: A colorful bird with shades of blue and green that is often seen perched on wires or tree branches.

  3. Indian Paradise Flycatcher: A stunning bird with long tail feathers, known for its elegant appearance.

  4. Asian Koel: A bird known for its distinctive "kuhoo" call, often associated with the arrival of the monsoon.

  5. Brahminy Kite: A medium-sized bird of prey with striking reddish-brown plumage.

  6. Indian Pitta: A brightly colored bird with a green and blue back and a coral red belly.

  7. Painted Stork: A large wading bird with striking black and white plumage and a distinctive pink bill.

  8. Indian Pond Heron: A small heron with mottled brown and white plumage, often found near water bodies.

  9. Greater Flamingo: These iconic pink birds can be found in various wetland areas across India.

  10. Sarus Crane: The tallest flying bird, with a distinctive red head and neck, often seen in wetlands.

  11. Indian Hornbill Species: Including the Indian Grey Hornbill, Malabar Pied Hornbill, and Oriental Pied Hornbill.

  12. Indian Vulture Species: Including the critically endangered Indian White-rumped Vulture and Long-billed Vulture.

  13. Indian Robin: A small bird known for its distinctive orange breast and white belly.

  14. Common Kingfisher: A brightly colored bird often seen perched near water bodies, known for its swift dives to catch fish.

  15. Rose-ringed Parakeet: A common parrot species with bright green plumage and a distinct ring around its neck.

3.Major threats to birds in India
 
3.1. Climate Change
  • The average global temperature has risen by over 1 degree Celsius since pre-industrial times, resulting in catastrophic consequences not only for humans but also for other living beings, like birds.
  • Climate change affects bird reproduction and survival through the disruption of species interactions by phenological mismatches, it occurs when the timing of annual events like breeding, nesting and migration become out of sync.
  • According to report "Mismatches in seasonal timing (of migration, breeding, emergence) between birds and their prey can reduce survival and reproduction and also lead to fatal competition with other species"
  • Soaring temperatures force sedentary birds to go through rapid adaptive changes. For instance, Amazonian birds over 50 years lost body weight to lose heat more efficiently
  • Moreover, sapping heat compels birds to change their behaviour. They tend to spend more time looking for shade instead of searching for food. This can have an adverse effect on their survival and reproduction.
  • Climate change leads to new and dangerous interactions between different species. A case in point is Hawaii, where with rising mercury, mosquitoes have colonised higher altitudes. This has given rise to malaria among mountain birds (Yes, humans aren’t the only ones who get malaria from mosquitoes)
3.2. Urbanisation
  • The most urbanised regions in India have the least number of bird species, the least number of rare species, and the fewest insectivorous species, according to the report.
  • It’s because urbanisation results in loss of natural habitat for birds and it exposes them to more air pollution and high temperatures.
  • Not only this, cities have noise pollution, which forces birds to “sing louder, or at different frequencies, or, in the worst case, to abandon otherwise suitable habitat,”
  • Meanwhile, light pollution may confuse and disorient them, causing them to collide with buildings.
  • Ultimately, lack of food supplies in urban areas leads to the homogenisation of bird communities as only behaviourally dominant species such as House Crows and feral Rock Pigeons are able to survive.
3.3. Monoculture
  • Monoculture is the practice of growing one type of seed in a field at a time.
  • In India, commercial monoculture plantations of rubber, coffee, and tea have been rapidly expanding in recent years. For example, tea plantations have grown from 5,214 sq km to 6,366 sq km from 2003 to 2020
  •  Oil palm plantations have also increased across the country with expanding hotspots located in Andaman and Nicobar Islands, and the northeastern Himalaya.
  • However, such plantations are detrimental to the well-being of birds. The report mentioned: “Commercial monocultures are known to harbour fewer bird species than natural forests within the same biome.”
  • For instance, oil palm plantations in Mizoram support only 14% of the bird species found in comparable rainforests.
  • In Uttarakhand, teak plantations can shelter just 50% of the total woodpecker species seen in the state’s sal forests.
3.4. Energy Infrastructures
  • In the context of the looming climate crisis, countries have started to generate power using renewable resources instead of depending on conventional methods like coal-fired power plants.
  • It has led to an increase of wind turbines in a country like India, where they have been installed in a wide range of landscapes including coastal areas, Western Ghats mountaintops, open arid lands, agricultural lands, and grasslands.
  • Although wind turbines are eco-friendly, they have emerged as a threat to birds, the report has revealed.
  • A wide range of species are known to have been killed due to collisions with wind turbines. Several of them have migrated to regions where there aren’t such giant devices.
  • The report said the transmission lines have also led to the death of many large-bodies species because of collision and numerous small-bodies species have been electrocuted. “A literature review reveals that over 60 species from 33 families of birds are affected by collisions and electrocution at power lines in India,”
