The Northern Fantail searches for insects in forests and along forest edges in northern Australia. A regional field guide describes a gray bird with a fine pale eyebrow and white throat, and notes that its tail is less fanned than that of other fantails.
It is about 19–22 cm long. The gray bird has a fine pale eyebrow and white on the throat, chin, and tail edges. The guide describes its bill as longer and its tail as less widely fanned than the Grey Fantail's.
It feeds on insects in forest margins, mangroves, vine thickets, along waterways, and in open forest. These are habitat records from the guide's region, not an exhaustive species-wide list.
