The Tickellās Leaf Warbler is a small, energetic passerine bird known for its rapid movements and high-pitched song. This warbler, named after British ornithologist Samuel Tickell, is primarily found in woodlands, scrublands, and riverine forests, including parts of the Sundarbans, where it can be spotted during migration.

š¶ A skilled insect hunter, the Tickellās Leaf Warbler plays an essential role in controlling insect populations in its habitats.
š¬ Morphology & Physical Characteristics
Size: Small, about 10ā11 cm (4 inches).
Weight: Lightweight, around 5ā7 grams.
Coloration:
Olive-green to yellowish-brown upper body for camouflage.
Pale yellowish-white underparts.
Distinct white or pale-yellow eyebrow stripe (supercilium).
Distinct Features:
Slender, pointed beak, specialized for picking insects.
Thin legs with strong claws, allowing it to perch easily.
Constantly flits between branches, searching for food.
š Habitat & Distribution
The Tickellās Leaf Warbler inhabits forested regions, scrublands, and riverine ecosystems.
š Key Habitats: ā Sundarbans (India & Bangladesh) šæ ā Winter migrant, seen in mangrove fringes. ā Himalayan Foothills & Northeast India š³ ā Breeding range. ā Myanmar, Thailand, and Southeast Asia š ā Common wintering areas.
š Preferred Habitat:
Dense forests & mangrove edges ā Provides food and protection.
Bushy scrublands & hilly regions ā Used for nesting in breeding areas.
Riverbanks & wetlands ā Attracts insects, their main food source.
⨠Special Features & Adaptations
1ļøā£ Hyperactive Forager ā Always moving through leaves, picking small insects and larvae. š 2ļøā£ Camouflaged Plumage ā Helps blend in with foliage to avoid predators. š 3ļøā£ Long-Distance Migrant ā Travels hundreds to thousands of kilometers during seasonal changes. š« 4ļøā£ Melodious, Repetitive Call ā Used for territorial defense and communication. š¶ 5ļøā£ Strong Feet for Perching ā Allows it to move quickly between tree branches. š³
šæ Presence in the Sundarbans
Although the Tickellās Leaf Warbler is not a resident species, it is frequently spotted in the Sundarbans during migration.
š Key Areas in the Sundarbans: ā Mangrove tree canopies ā Active among branches hunting insects. ā Shrubby undergrowth & forest edges ā Prefers mixed vegetation zones. ā Seasonal stopover sites near riverbanks ā Found during migration periods (SeptemberāApril).
ā ļø Threats & Conservation Challenges
šØ Habitat Loss & Deforestation ā Loss of woodlands reduces their nesting and feeding grounds. šØ Climate Change ā Affects migration patterns and food availability. šØ Pesticide Use ā Reduces the availability of insect prey. šØ Predation by Larger Birds ā Being small, it often falls prey to raptors and other avian hunters.
ā Conservation Efforts
ā Forest Conservation Initiatives ā Protecting natural tree cover. ā Sustainable Eco-Tourism ā Raising awareness about bird conservation. ā Wetland & Mangrove Protection ā Preserving stopover sites for migratory birds.
šØ Conservation Status
š IUCN Red List:Least Concern (Stable Population). š CITES: Not Listed. š Indian Wildlife Protection Act: Schedule IV (Moderate Protection).
Although the population is currently stable, habitat loss could threaten their long-term survival.
The Tickellās Leaf Warbler is a small but vital bird species that helps regulate insect populations. Its presence in the Sundarbans during migration makes it an exciting sight for birdwatchers. By preserving forests, mangroves, and wetland habitats, we can ensure this migratory species continues to thrive in its natural range. šæš¦
