Why in News?

Recently the Kenyan government has announced an action plan to eliminate a million Indian House Crows (Corvus splendens) by the end of 2024.

• This decision stems from the birds' significant negative impact on local ecosystems and their nuisance to the public, particularly in the Kenyan coastal region.

What is the Kenyan Government Action Plan?

• Invasive Species Issue: The Indian House Crow is described as an invasive alien species from India and parts of Asia, introduced to East Africa via shipping activities.
• Ecological Impact: The crows prey on endangered local bird species, destroy nests, and eat eggs and chicks, leading to a decline in indigenous bird populations.
  • This decline disrupts the ecosystem, allowing pests and insects to proliferate, further harming the environment.
• Historical Effort: A similar effort in Kenya over 20 years ago managed to reduce their numbers temporarily.
• Government and Community Response: An action plan to combat the crow menace includes mechanical and targeted methods for culling the birds, and use of licensed poison for population control.
