What is a "yellowhead"?

A yellowhead, also known as the yellowhead honeyeater, is a small passerine bird native to New Zealand. It is named after its distinctive bright yellow head, contrasting with its olive-green upperparts and yellow underparts. This bird is characterized by its energetic and agile nature, often foraging in the forest canopy for insects and nectar. The yellowhead is known for its melodic and varied song, consisting of high-pitched trills and whistles that echo through the forest. It is a social species, often seen in small groups or family units, and it builds intricate cup-shaped nests made of moss, lichens, and spider webs. The yellowhead is an endemic species of New Zealand and plays an essential role in the ecosystem as a pollinator and seed disperser.
