Evolution and systematics

Fantails, also called wagtail flycatchers, are a component of the large Australo-Papuan songbird group, the so-called "corvine radiation." They are closest to the drongos of the Dicruridae family and monarch flycatchers of the Monarchinae family. The fantails are either classified in their own family or as a subfamily of the monarch flycatchers, or in a broader drongo-monarch grouping. There is no doubt that they represent a distinctive group of insectivorous birds. Generally the 40 or more species are referred to the single genus Rhipidura, although the yellow-breasted fantail (R. hypoxantha) is sometimes placed in the monotypic genus Chelidorhynx. Within the genus Rhipidura, there are several distinct subgroups.

The largest of the fantails, the willie wagtail (R. leucophrys), is perhaps the most atypical member of the genus. It spends much more time on the ground than other species. The northern fantail (R. rufiventris) is one of several more sedate species; although capturing prey in flight, these do so without the aerial flourishes of most fantails. The thicket-fantails, like the sooty thicket-fantail (R. threnothorax), are shy and secretive inhabitants of dense rainforest understory. The remaining species of fantail, however, are active and conspicuous. These are distributed across the family's range. The gray fantail (R. albiscapa), streaked fantail (R. spilodera), and rufous fantail (R. rufifrons) species-groups each include a number of species spread across substantial parts of Indonesia, Australasia and the southwestern Pacific. Other species have less obvious connections with other fantails. The tiny yellow-bellied fantail has a unique color pattern and other minor differences, and the blue-headed fantail (R. cyaniceps) and blue fantail (R. superciliosa) are also unusual in their color; otherwise these are fairly typical members of this family.

A species may be distributed on mainlands and many islands across a wide area. This makes it difficult to differentiate between species when they are so closely related. The species limits among the 13 or so members of the rufous fantail group are sometimes rather arbitrary. In his detailed 1987 review of Australian populations of the gray fantail, Julian Ford recognized the mangrove-inhabiting population of the northern coasts as a distinct species, the mangrove fantail (R. phasiana). Subsequently, studies by Richard Schodde and Ian Mason of the gray fantail both in and beyond Australia recommended that the New Zealand populations be specifically classified as New Zealand fantails (R. fuliginosa), and the Australian birds as R. albiscapa. Richard Holdaway and his colleagues went even further, dividing the fantails of New Zealand's North, South, and Chatham Islands into three different species. Multi-island distributions have given rise to

numerous subspecies in widespread species; the northern fantail, for example, has 24 named forms scattered across the Bismarck Archipelago, northern Australia, New Guinea, and islands of the Moluccas and Lesser Sundas.

On occasion, the two small flycatchers in the genus Culicapa have been associated with the fantails. Although the proper taxonomic placement of these south and southeast Asian species is uncertain, it does not appear to belong to the genus Rhipidura.

Physical characteristics

Fantails are small birds, ranging from the yellow-bellied fantail at 5.5 in (15 cm) and 0.2 oz (6 g), to the larger willie wagtail at 8.5 in (21.5 cm) and 0.9 oz (25 g). The obvious feature of this family, from which the group name is derived, is the distinctive long, rounded, fan-shaped tail, which may represent 50% or more of a bird's total length. Fantails also have the flat, triangular bill characteristic of many aerial insectivores. The bill is surrounded by rictal bristles, in an unusual double row arrangement. With the exception of the more terrestrial species, fantails have short tarsi and small feet. The wings are rather rounded, sacrificing speed but allowing a highly maneuverable, usually very buoyant flight.

Fantails are generally not brightly plumaged, with the major colors being brown, rufous, white, gray, or black, or a combination of these. This generalization breaks down along the northwestern and western periphery of the family's distribution, where two species have large amounts of blue in the plumage and another one, yellow. The overall color of many species is muted or drab, but a few species, such as the black-and-cinnamon fantail (R. nigrocinnamomea), have boldly contrasting colors. Males and females rarely exhibit dimorphism in their plumage; an exception is the black fantail (R. atra) of New Guinea, with black males and rufous females. The New Guinea dimorphic fantail (R. brachyrhyncha) also has two color phases: a dark one in which the tail is black and rufous, and a light phase with a light gray tail. Young fantails look like adults with washed-out colors and rusty edges to some feathers, particularly the wing coverts. Widespread species, particularly those that are found over a number of islands, show marked plumage variation among the populations.

Distribution

Although primarily an Australasian family, the fantails distribute well beyond this region. Species are found in eastern Pakistan, India, Sri Lanka, the Himalayas, southern China,

southeast Asia, the Philippines, Indonesia, New Guinea, Australia, New Zealand, and the islands of the southwestern Pacific, east of Samoa and north to Micronesia. Several species may coexist, particularly in New Guinea, with up to seven found in the same locality. Some species are quite widespread, such as the white-throated fantail (R. albicollis), which is found from eastern Pakistan through south and southeast Asia to Borneo. Another example is the rufous fantail, which ranges from the Moluccas to the Santa Cruz islands in the east and to Micronesia in the north. Other species are restricted to only a single small island; the Ponapé fantail (R. kubaryi) and Matthias fantail (R. matthiae) are endemic to Ponapé, Micronesia, and to Mussau, in the Bismark Archipelago, respectively.

Habitat

The fantail family has representatives in many types of habitats, but most species are found in rainforest, either exclusively or as part of their broader range of habitat preferences. The mangrove fantail, as the name suggests, is restricted to mangroves. In Australia, the rufous fantail is primarily a bird of rainforest and wet sclerophyll forest in the breeding and non-breeding seasons; during migration, individuals may wander into a range of more open habitats, including city centers. The greatest diversity of habitat preferences is that of the willie wagtail. Although it favors open situations, this species occurs in all but the densest rainforest, and seems equally at home in deserts and city parks. Where several species of fantails occupy the same habitat, they favor different elevations in the forest or different parts of the tree. Some, like the sooty thicket-fantail, choose low, dense thickets. The willie wagtail is the most terrestrial species, spending much of its time foraging on the ground.

Behavior

The tail is usually held cocked, alternately fanned and closed, and often swung from side to side while a bird is perched or moving about the foliage. This tail posture is also used when species engage in highly aerobatic, looping flights to capture flying insects. So active are these flights at times that they have been described as "hysterical." These species are restless, rarely perching still for long. This behavior gave the gray fantail the colloquial nickname of "mad fan". Some species, such as the northern fantail, are more sedate, spending more time perched and making more direct sallies for insects. The willie wagtail rarely fans the tail, but swings it energetically from side to side.

Many fantail species are tame and confiding towards humans. They may come close to capture insects flushed by a moving observer. Other large, harmless animals are used in a similar fashion; willie wagtails frequently use domestic cattle both as a perch and to flush insects. This behavior contrasts with the response to animals perceived as predators or territorial intruders. Fantails can be boldly aggressive towards larger birds, fearlessly attacking birds of prey, even landing on their backs. Aggressive behavior in a willie wagtail is signaled by its rasping, scolding calls and a greatly expanded white eyebrow. If the conflict involves a territorial dispute, the losing bird will shrink the eyebrow until it is no longer visible. The thicket-fantails, unlike most species, are shy and secretive in the presence of humans and can be difficult to see as they skulk in dense undergrowth.

As a general rule, populations near the equator do not migrate. Thus, most tropical species are sedentary, remaining in the same area throughout the year. In more southern temperate regions, and at higher elevations, birds may exhibit marked seasonal movements. In Australia, the rufous fantail regularly moves north and south along the east coast. The gray fantail has more pronounced shifts, with southeastern populations moving extensive distances north and northwest

in winter. Species like the white-throated and yellow-bellied fantails, which spend the summer in the Himalayas, move to lower altitudes at the end of the season.

Fantails are not particularly noted songsters, although their voices are by no means unpleasant. They are not strong and the calls are simple. Songs, which can be uttered frequently, are rapid and enthusiastic. That of the gray fantail has been likened to the notes of a violin. The exception to possessing a soft song is the willie wagtail. Both its scolding call and song are robust compared to those of other fantails and can be heard for some distance. The song, transliterated as "sweet pretty creature", may be repeated for quite extended periods, particularly on moonlit nights.

Feeding ecology and diet

Other than that of a few larger species, such as the willie wagtail, the bill of fantails is not strong enough to handle large, robust prey. The major food is small insects and other invertebrates. Larger prey, such as moths, may be hammered on a branch to subdue and render it suitable to be eaten. The willie wagtail has captured and eaten small skinks. Most prey are caught in the air, gleaned from foliage, or, less often, pursued on the ground. The flight of a gray fantail for a flying insect can be an impressively dizzying aerial pursuit. Rapid loops and sudden changes of direction appear to threaten to break the bird apart. The tail is held cocked and spread as a

bird moves through the foliage, and it has been suggested that this may assist in flushing insects.

In a study of three coexisting Australian fantails, Elizabeth Cameron found that they partitioned the environment, each selecting different heights and sections of the substrate, and using different foraging techniques, thus reducing overlap and competition. During the summer, gray fantails fed across a broad range of elevations, occasionally in the canopy at heights of about 130 ft (40 m). The predominant foraging method was to search for prey from a lookout perch, then pursue it in the air, before returning to a new vantage point. Rufous fantails generally fed lower, in the understory and shrub strata, and spent more time actively moving through the foliage flushing insects. Willie wagtails remained within 10 ft (3 m) of the ground and often on it, either capturing prey in the air with short flights or pursuing it on foot on the ground. In winter, when the rufous fantails migrated away from the area, gray fantails became more aerial and willie wagtails more terrestrial.

Reproductive biology

Some or all aspects of the breeding biology are unknown for a number of the rarer or more remote species. Conversely, several of the common, widespread species have been particularly well studied. Most fantails have quite similar breeding patterns. Both sexes construct the nest, a small, tidy cup of fine grass stems bound together by a thick external coating of cobwebs. This is placed in a horizontal fork or sometimes in a human-made structure or other suitable site, from 3–50 ft (1–15 m) from the ground, but usually within less than 10 ft (3 m). Most species for which the nest is known attach a dangling "tail" of nesting material to its underside. The clutch includes 2–4 eggs. These are pale or cream, marked with brown or gray blotches and spots, which form a wreath at the larger end or around the midline. Eggs of the yellow-bellied fantail differ somewhat by being cream or pinkish cream with a cap on the larger end consisting of pinkish brown stippling. Both parents incubate the eggs for 12–14 days. After hatching, chicks remain in the nest for 13–15 days, attended by both parents.

Because there is little attempt at concealment, fantail nests may be subject to considerable predation by larger birds. Richard Major and his team studied predation rates and the major perpetrators by building artificial nests with eggs made from modeling clay. Through direct observation and by identifying the bite marks left in the false eggs, he determined that more than ten avian species and several small mammals attempted to steal the eggs. The major predator was the pied currawong (Strepera graculina), which was responsible in more than half of the directly observed raids. Fantails also suffer from nest parasitism by cuckoos. A rufous fantail can be the host of a vigorously begging young pallid cuckoo (Cuculus pallidus), a bird that is up to eight times its weight.

Conservation status

Many species of fantails are common, and those found on larger landmasses appear not to be under threat. Several island populations, however, have been identified as in threatened or approaching this unfortunate status. The IUCN and Birdlife International have listed two species as Vulnerable. The Malaita fantail (R. malaitae), on Malaita, in the Solomon Islands, have a small estimated population, with recent records from only two locations. For this species, the threat factors affecting it are uncertain at present. The Manus fantail (R. semirubra), from the Admiralty Islands (Papua New Guinea), also has a small range. Once common on Manus Island, there have been no records since 1934. Although it is still found on neighboring islands, the reasons for this decline are not known.

Five species are considered Near Threatened: cinnamon-tailed fantail (R. fuscorufa) and long-tailed fantail (R. opistherythra), both of the Tanimbar Islands; Cockerell's fantail (R. cockerelli), Solomon Islands; dusky fantail (R. tenebrosa), San Christobal, Solomon Islands; and Matthias fantail of the Mussau, Bismarck Archipelago. Significant amounts of logging across critical parts of these species' ranges has been implicated as a threatening process in all cases.

Because distribution of some species is restricted to remote islands or high elevations, it is difficult to assess the status of some populations. These may be not be under current threat but, because of small population sizes, they are potentially susceptible to introduced species or habitat alteration.

Significance to humans

In places, fantails are well known because they are common and active. Combined with their tame and confiding nature around humans, this has made them particular favorites among birdwatchers and the general public. In parts of New Guinea, the willie wagtail is thought to be the ghost of a paternal relative. A singing bird around a newly planted garden means that crops will flourish. Elsewhere, it has the reputation as a gossip; it is not persecuted, but important business is not discussed when the bird is present.

physical characteristics

6.5–7.1 in (16.5–18.0 cm); 0.35–0.6 oz (10–17 g). Gray-brown plumage with buff belly and white lateral tail feathers. White streaks on breast; white brow and chin to throat.

distribution

Northern Australia, New Guinea, Bismarck Archipelago, Moluccas, Lesser Sunda Islands. Found mainly in the lowlands

and hills, locally up to 5,400 ft (1,640 m) on New Britain.

habitat

This species can be found in a range of habitats, including open eucalypt woodland, rainforest fringes, mangrove forest, monsoon forest, riverine vegetation, wooded swamps, tall secondary growth, forest edges, and garden areas.

behavior

Territorial, usually solitary or in pairs. Often conspicuous when it chooses exposed perches. Often joins mixed-species feeding flocks. Less active than other fantails; spends more time perching and engages in more sedate aerial pursuits. Generally quiet, unobtrusive, undemonstrative. Typical stance upright with the tail held vertically.

feeding ecology and diet

Eats a variety of insects obtained almost entirely by hawking, although sometimes gleaned from branches and leaves. Commonly joins mixed-species foraging flocks of other small insectivorous songbirds.

reproductive biology

A pair may produce 1–2 broods per season, which runs from Aug.–Jan. in Australia and from the mid-dry to the mid-wet season in New Guinea. Both parents build the nest, incubate, and care for the young. The female lays two spotted eggs in the small cup nest. As with most fantails, this has a tail about 2.8 in (7 cm) long hanging from the underside.

7.1–8.7 in (18–22 cm); 0.6–0.8 oz (17–24 g). A large bird with black plumage and white brow and breast.

distribution

R. l. melanoleuca: Moluccas, New Guinea, and surrounding islands, Bismarck Archipelago, Solomon Islands; R. l. picata: northern Australia; R. l. leucophrys: southwest, southern, central, and southeast Australia.

habitat

This species can be found in almost any habitat except the densest rainforest or eucalypt forest; it prefers relatively open areas, from sea level to 9,240 ft (2,800 m).

behavior

Terrestrial for much of its time, running, walking, or hopping on the ground. As it does so, the tail is usually held elevated but not often fanned. When pausing, the tail is constantly waved from side to side and up and down. The willie wagtail is usually seen singly, although mates often are nearby. A conspicuous, active, and bold bird that often draws attention to itself by harassing or attacking larger animals that are considered as predators or enter territory during breeding. An aggressive individual, it conspicuously expands its white eyebrows. In Australia, this species is mainly sedentary or locally nomadic, while in New Guinea it may leave some areas in the dry season, returning to breed during the rains. The song, rendered as "sweet pretty creature", may be heard incessantly during breeding, often throughout a moonlit night. There is also a harsh scolding note given when a bird is agitated.

feeding ecology and diet

Feeds on insects, larvae, and occasionally small lizards. Much food is obtained by hawking from perches for insects on the wing, or snatching them from ground after short runs.

reproductive biology

Although breeding occurs mainly in Jul.–Feb. (Australia), this species can nest in any month, conditions allowing. This may yield up to four or more broods to be reared in a season. Both parents share nest building, incubation, and care of the young. The nest is made of grass and fine bark strips, covered with spider web, but it lacks the tail of most fantails; this is placed on horizontal fork or in man-made structure or other suitable site, usually less than 16.5 ft (5 m) above the ground. The eggs are cream with brown and gray speckles forming a wreath at larger end. Incubation, 14–15 days; age at fledging 14 days.

conservation status

Common throughout its range.

significance to h umans

A well-known and popular bird in Australia. In parts of New Guinea it is considered to be a gossip or the ghost of a paternal kinsperson bringing good luck.
