Ruby-cheeked Sunbird

Chalcoparia singalensis

紫颊太阳鸟

IUCN: Least Concern Found in China

Introduction

The sunbird inhabits forests of South and Southeast Asia, ranging from the eastern Himalayas and Bangladesh through Indochina to the islands of Indonesia. It occupies tropical lowland forests, mangrove forests, and montane forests up to 1,500-1,800 meters elevation. The species feeds on nectar while foraging among flowering plants. Eleven recognized subspecies are distributed across its range, exhibiting regional variations in plumage and size. While not considered globally threatened, habitat deforestation and fragmentation may affect populations in parts of its range.

Distribution & Habitat

Found across Bangladesh, Bhutan, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Thailand, and Vietnam. The species occupies subtropical and tropical moist lowland forests, mangrove forests, and subtropical or tropical moist montane forests. Subspecies show geographic specialization: assamensis occurs from the eastern Himalayas and Bangladesh to south China, northern Thailand, and northern Myanmar; koratensis ranges through eastern Thailand and Indochina; various subspecies are distributed across different regions of the Malay Peninsula, Sumatra, Borneo, and Java.
