The Fire-tailed sunbird chooses to inhabit temperate forests and sub-tropical or tropical damp mountain forests.

These birds, while primarily consuming nectar, will also incorporate insects into their diet when the opportunity arises.

The breeding behaviors of this species in the Himalayas and the Hengduan Mountains are not well understood, but it has been noted that the nesting period typically lasts around 19.5 days. Both male and female birds participate in feeding their young, although females tend to feed their offspring more frequently than males. Compared to other birds that live at lower altitudes, the Fire-tailed Sunbird invests more energy into caring for its offspring by laying fewer eggs and providing greater parental care to its young.

The Fire-tailed Sunbird is fortunately not considered to be at high risk, as it falls under the category of Least Concern on the IUCN Red List. You can observe and hear this bird through the video provided below.
