Yuhina brunneiceps

The Taiwan yuhina's most distinctive feature is its chocolate brown crest paired with a black beard stripe descending from its beak, a combination that sets it apart from other members of its genus.

The species measures 12 to 13 centimeters in length and weighs about 0.0125 kilograms, placing it firmly among small songbirds. Its back, wings and tail are dark ash brown, while its lower breast is noticeably lighter in color, creating a subtle two-toned effect along its body.

While the Yuhina genus shares a broadly similar body plan across its members, the Taiwan yuhina's particular coloration pattern is described as rather distinctive within the group, helping observers tell it apart from related species.

The Taiwan yuhina occupies hill forests across a range of about 13,700 square kilometers, entirely within Taiwan. It favors elevations between 1,000 and 3,200 meters, but is most commonly encountered between 1,500 and 2,500 meters, descending to lower altitudes during winter.

It keeps to a semi-open, lower forest layer and is notably gregarious, active and tame, frequently joining mixed flocks alongside tits. These flocks maintain a constant soft chatter while feeding, and the species' own call, rendered as "twi-MI-chiu," resembles the phrase "We MEET you."

Observation records through the year show a clear seasonal pattern, with counts rising sharply in the early months and peaking around March before declining through the rest of the year, suggesting greater presence or detectability during that period, though these figures reflect presence records rather than actual population size.

1. The name Yuhina comes from a Hindi word meaning "a small, singing bird," while brunneiceps combines Latin roots for "brown" and "headed," together describing the species' characteristic brown head.
2. The species was formally described by Ogilvie-Grant in 1906.
3. The Taiwan yuhina is recognized as part of Taiwan's cultural and natural heritage, featured in collections dedicated to showcasing the island's biodiversity.
