and ranges upward to 3,700 m. Mountains it inhabits include Alishan, Da Yu Ling, Hehuanshan, Yu Shan, and the higher areas of Anmashan. They prefer conifers in which to forage, and are usually found in the forest canopy, but will sometimes venture into lower vegetation. An analysis of the distribution of Taiwan's 17 endemic bird species, using data from bird surveys conducted from 1993 to 2004, classified the firecrest as uncommon (along with the Formosan magpie, Taiwan bush warbler, yellow tit and Taiwan barwing). It found that the flamecrest occurred in high- and mid-altitude coniferous forests, and in high-altitude broad-leaved mixed forests, mainly at 2000–3600 m above sea level. The sites where it was recorded had an average altitude of about 2550 m, the highest of all the endemic birds. Its habitats had the coldest mean temperature and lowest warmth index of all 17 endemics, as well as the highest annual rainfall for the five uncommon species, though its distribution regarding vegetation and human disturbance was similar to those of the others. Behaviour Flamecrests are active and restless birds, hopping and fluttering about in the canopy. These lively songbirds are mainly solitary but will move around actively in small, loose flocks of their own species as well as with coal tits and Eurasian nuthatches. The flight is weak and whirring. Their breeding biology is poorly known. Feeding The flamecrest is primarily an insectivore. The birds may be seen feeding on insects and their larvae on the branches and leaf sheathes of trees in coniferous forests, hovering and gleaning from leaf to stem. Weeds and berries may be taken occasionally. A study of the foraging ecology of alpine forest birds on conifers in the Taroko National Park found that, when compared with Eurasian nuthatches, coal tits, green-backed tits and black-throated tits, flamecrests were the most generalised foragers, utilising almost all of the crown of a tree, rather than specialising in parts of it as with the other species, with which it associates in mixed-species foraging flocks during the non-breeding season. Voice Flamecrests have fine, shrill and high-pitched calls, zi zi yi. Although noisy at close range, the voice is soft and does not carry far.
