Blyth's Leaf Warbler

Phylloscopus reguloides

西南冠纹柳莺

IUCN: Least Concern Found in China

Introduction

A small passerine bird in the family Phylloscopidae. Formerly classified within the Old World warbler assemblage, this species occupies a range extending through Southeast Asia, southern China, and along the Himalayan foothills to northern Pakistan. Its preferred habitat consists of subtropical and tropical moist montane forests. The species demonstrates complex birdsong patterns characterized by increased variation between distinct song types, contributing to overall song complexity measured by the number of distinct notes.

Distribution & Habitat

The species' range encompasses Southeast Asia, southern China, and extends along the Himalayan region to northern Pakistan. It inhabits subtropical and tropical moist montane forests throughout this geographic area. No specific migration patterns are described in available sources.

Behavior & Ecology

The species is noted for its complex vocalizations, with song complexity measured by the number of distinct notes. The complexity results from increased variation between different song types rather than simple note count. No specific information on diet, breeding behavior, or social structure is available.

Culture

The species was named in honor of Edward Blyth, an English zoologist who contributed significantly to ornithological taxonomy and study.
