In Rajaji National Park
Rajaji National Park, with its varied ecosystems ranging from riverine forests and grasslands to broadleaf woodlands, provides the perfect habitat for the Yellow-bellied Fantail. The bird is commonly spotted in:

Behavior and Ecology
The Yellow-bellied Fantail is a lively and agile bird, often seen flitting from branch to branch or hovering mid-air. Its behavior is marked by quick, darting movements and a constant fanning of its tail.
Feeding Habits
This insectivorous bird is an expert at aerial foraging, feeding on small insects and spiders. It employs a strategy called “hawking,” where it captures prey mid-flight. The bird’s agility and precision make it a vital part of the ecosystem by keeping insect populations in check.

- Both parents participate in feeding the chicks, showcasing a cooperative parenting style.
Social Behavior
Fantails are known for their gregarious nature. While they can often be seen foraging alone or in pairs, they sometimes join mixed-species foraging flocks, enhancing their chances of spotting prey.
