🐦 Swinhoe’s White-eye (Zosterops simplex) – The Lesser-Known Canopy Dweller

The Swinhoe’s White-eye is a small, social songbird closely related to the Indian White-eye (Zosterops palpebrosus). This species is known for its distinct white eye-ring, vibrant green plumage, and melodious calls. Although more common in China and Southeast Asia, it is occasionally spotted in India’s coastal and mangrove regions, including parts of the Sundarbans during seasonal movements.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Aves
  • Order: Passeriformes
  • Family: Zosteropidae
  • Genus: Zosterops

🌿 Presence in the Sundarbans

While not a resident species, the Swinhoe’s White-eye has been occasionally spotted in the Sundarbans, particularly where flowering and fruit-bearing trees are present.

šŸ“Œ Key Areas in the Sundarbans:
āœ” Mangrove edges & mixed forest patches – Preferred foraging grounds.
āœ” Flowering shrubs & canopy trees – Attracts them due to nectar sources.
āœ” Seasonal sightings in riverine habitats – Possible during migration.

āš ļø Threats & Conservation Challenges

🚨 Habitat Loss Due to Deforestation – Reduces nesting and feeding grounds.
🚨 Climate Change Impacting Migration – Alters food availability.
🚨 Declining Insect Populations – Affected by pesticide use.
🚨 Illegal Pet Trade – Occasionally captured due to its small size and attractive appearance.

āœ… Conservation Efforts

āœ” Mangrove & Woodland Conservation – Protecting their habitats.
āœ” Eco-Tourism & Birdwatching Awareness – Encouraging conservation through education.
āœ” Pollution Control & Pesticide-Free Zones – Supporting a healthy insect population.


🚨 Conservation Status

šŸ“Œ IUCN Red List: Least Concern (Stable Population).
šŸ“Œ CITES: Not Listed.
šŸ“Œ Indian Wildlife Protection Act: Schedule IV (Moderate Protection).

While not endangered, deforestation and climate change could impact their distribution in the future.


The Swinhoe’s White-eye is a small but ecologically important bird, playing a role in pollination and insect control. Its presence in the Sundarbans, though occasional, highlights the region’s rich avian diversity. By protecting forests and promoting sustainable tourism, we can help preserve this cheerful, social species. 🌿🐦
