Extensive Definition

Fantails are small insectivorous birds of southern Asia and Australasia belonging to the genus Rhipidura in the monotypic family Rhipiduridae. Most of the species are about 15 to 18 cm long, specialist aerial feeders, and named as "fantails", but the Australian Willie Wagtail, is a little larger, and though still an expert hunter of insects on the wing, concentrates equally on terrestrial prey.
The true wagtails are part of the genus Motacilla in the family Motacillidae and are not particularly close relatives of the fantails.


The fantails are small bodied (11.5-21 cm long) birds with long tails; in some species the tail is longer than the body and in most the tail is longer than the wing. When the tail is folded it is rounded at the end, but when spread in display or aerial foraging it has a characteristic fan shape that gives the family its name.
Fantails adopt a hunched horizontal posture most of the time, with the wings drooped and held away from the body and the tail half cocked. There are some exceptions to this, particularly the Northern Fantail of New Guinea and the Cockerell's Fantail of the Solomon Islands, which have a more upright posture reminiscent of the monarch flycatchers.
The wings of fantails are tapered and have sacrificed speed for agility, making fantails highly efficient at catching insect prey. Overall the fantails are strong fliers, and some species can undertake long migrations, but the thicket-fantails (Sooty Thicket-fantail, White-bellied Thicket-fantail and Black Thicket-fantail) are very weak fliers, and need to alight regularly.
The bills of fantails are typical for arial insect eating birds, being flat and triangular. The gape is surrounded by two rows of rictal bristles which are long, often as long as the bill.The bills of most species are fairly weak, limiting fantails to softer insects, although the more terrestrial Willie Wagtail has a relatively stronger bill.
The plumage of most fantails shows some variation, most species are relatively uniform with some markings.

Range, migration and habitat

Fantails are an Australasian family that has spread as far as Samoa to Pakistan. In the south the Grey Fantail ranges as far as the Snares off New Zealand, in the eastern extend of the family has several endemic forms in western Polynesia. There are numerous species in Indonesia, the Philippines and in South East Asia, and the family ranges into southern China, India and the Himalayas. Some species have a widespread distribution, particularly the Willie Wagtail, Grey Fantail, White-throated Fantail and Northern Fantail; others have a highly restricted range and in the case of some insular species may be restricted to a single island. The Mussau Fantail is restricted to a single island in the Bismark Archipelago, and the Kadavu Fantail has a similarly restricted distribution in the Kadavu Group of Fiji.
Most fantails, particularly the tropical or insular forms, are sedentary and undertake no migration. Some northern and southern species undertake a variety of movements; the Yellow-bellied Fantail of the Himalayas is an altitudinal migrant, breeding between 1500-4000m, but moving to lower altitudes (as low as 180m) in the winter. Some Australian fantails undertake seasonal migrations, although these show considerable variation even within individual species. Most populations of the Rufous Fantail exhibit little migratory behaviour, but the south-eastern population moves en-mass to northern Queensland and New Guinea.
Fantails exhibit fairly catholic tastes in habitat; while the majority of species are found in rainforests fantails exist in most available habitats from deserts and mangrove forests to highly modified agricultural and urban environments. Most species are able to survive in a variety of habitats. Of all the species the Mangrove Fantail has the most restricted habitat requirements, being entirely restricted to mangrove forests over some of its range, although it can exist 3km away in the absence of other fantails. Some of the more primitive species are generally more restricted to primary rainforest, but most other species can survive in more disturbed forest. The most adaptable species is the Willie Wagtail, which is abundant in every habitat type in Australia except for dense rainforest.


The behaviour of many species of fantail has not been studied, but overall the family is highly uniform in its habits. Anecdotal observations of less studied species suggest a high degree of similarity with the better studied species. Fantails are highly active birds, with several of the smaller species continuously on the move; even when perched they continue to rock back and forth, spin 180° on the spot, wag their tail from side to side or fan and unfan it. In flight they are highly agile and undertake highly aerobatic and intricate looping flights.

Diet and foraging

The majority of the diet of fantails composes of small insects and invertebrates. The larger Willie Wagtail is capable of tackling small skinks, but this is exceptional. Insect prey is generally small and easily handled, but larger items sometimes need to be subdued by banging it on branches, an action that also removes the wings of larger prey items like moths.
There are two general techniques used by the family in order to obtain prey. The first is known as "static searching", where the fantail will remain at a perch and watch for ariel prey which it will then sally towards and snatch from the air before returning to the perch in order to consume and resume searching. The second method used is known as "progressive searching", where the fantail moves through vegetation searching for insect prey which it gleans; the movement of the searching fantail also flushes out hidden prey which is also pursued and consumed. The Willie Wagtail performs a terrestrial version of this technique, pumping its tail from side to side and undertaking quick darting movements across open ground in order to flush up prey.
Fantails frequently form associations with other species in order obtain prey. Some species perch on the backs of cattle, which they use both as a vantage point and because the cattle flush up insects. This behaviour has given the Willie wagtail the nickname "Shepherd's Companion". Fantails are often very bold around people and will approach them closely in order capture insects flushed by them. Different species are also frequently found in Mixed-species feeding flocks, travelling with other small insectivorous birds on the periphery of the flocks taking advantage of flushed prey.


Fantails are territorial and aggressively defend their territories from conspecifics (other members of the same species) as well as other fantail species and other flycatchers. Within the territory the female selects the nesting site, these sites are often close to the previous year's nest. Breeding responsibilities, nest building,incubation and chick feeding, are shared between both sexes.
The nest, a small cup of grass stems neatly bound together in spider silk, takes around 10 days to construct. Many species incorporate a trailing tail into the base of the nest; this possibly breaks up the shape of the nest, although there little other effort is made to conceal the nest. To compensate for the high visibility of the nest fantails will aggressively defend their chicks from potential predators.
Female fantails will also distract a potential predator by appearing to be injured and luring the predator away from the nest. While the female is pretending to be injured the male may continue to attack the predator. In spite of this fantails have a generally low nesting success.
