🐦 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.

👀 Named after British naturalist Robert Swinhoe, this bird is closely related to other white-eye species, with subtle differences in plumage and vocalizations.
🔬 Morphology & Physical Characteristics
Size: Small, about 8–10 cm (3–4 inches).
Weight: Lightweight, around 9–12 grams.
Coloration:
Bright greenish-yellow upper body.
Whitish underparts.
Prominent white eye-ring, a signature feature.

🌍 Habitat & Distribution
The Swinhoe’s White-eye inhabits forests, mangroves, and urban green spaces, preferring areas rich in flowering plants.
🌎 Key Habitats: ✅ Sundarbans (India & Bangladesh) 🌿 – Occasionally seen in mangrove edges. ✅ China, Taiwan, and Southeast Asia 🌏 – Primary breeding range. ✅ Northeast India & Coastal Woodlands 🌳 – Sighted in select regions.
📌 Preferred Habitat:
Mangrove forests & riverbanks – Provides food and nesting sites.
Flowering tree canopies & fruiting plants – Supports their omnivorous diet.
Urban parks & plantations – Found in areas with abundant flowering plants.
✨ Special Features & Adaptations
1️⃣ Social & Gregarious – Often moves in small, active flocks, constantly chirping. 🐦 2️⃣ Omnivorous Feeder – Feeds on nectar, fruits, and small insects. 🍃🐛 3️⃣ Soft, Musical Call – A sweet “tzee-tzee” sound, used for communication. 🎶 4️⃣ Pollination Role – Aids in flower pollination while feeding on nectar. 🌸 5️⃣ Fast, Darting Flight – Moves quickly between branches, rarely staying still. 🚀
🌿 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.
📌 Key Areas in the Sundarbans: ✔ Mangrove edges & mixed forest patches – Preferred foraging grounds. ✔ Flowering shrubs & canopy trees – Attracts them due to nectar sources. ✔ Seasonal sightings in riverine habitats – Possible during migration.
⚠️ 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.
✅ Conservation Efforts
✔ Mangrove & Woodland Conservation – Protecting their habitats. ✔ Eco-Tourism & Birdwatching Awareness – Encouraging conservation through education. ✔ Pollution Control & Pesticide-Free Zones – Supporting a healthy insect population.
🚨 Conservation Status
📌 IUCN Red List:Least Concern (Stable Population). 📌 CITES: Not Listed. 📌 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. 🌿🐦
