This small yet vibrant bird adds to the rich tapestry of avian life within the park. In this comprehensive overview, we will delve into the characteristics, habitat, behavior, and conservation status of the Iora in Rajaji National Park, while also addressing frequently asked questions to enhance understanding.
A Brief Overview
The Iora is a small passerine bird that belongs to the family Aegithinidae. It is renowned for its striking plumage and melodious calls. The bird’s most distinctive feature is its bright green and yellow coloration, which makes it a visual treat for bird watchers. Males are especially vivid, sporting a bright green body with contrasting yellow underparts, while females are generally more subdued in color.
Physical Characteristics:
- Size: The Iora measures about 11 to 13 centimeters in length.
- Coloration: Males are adorned with vivid green and yellow plumage, whereas females have a more muted olive-green coloration.

Occasionally, it may also consume small fruits and nectar. The bird’s feeding behavior is often accompanied by its melodious call, which is a series of high-pitched notes.
Breeding:
During the breeding season, which typically occurs from April to June, the Iora constructs a small, cup-shaped nest in the fork of a tree. The female lays a clutch of 2 to 4 eggs, which she incubates for about 14 to 16 days. Both parents participate in feeding the chicks, which fledge within 14 to 16 days after hatching.
