Fantail River
Fantails are small insectivorous songbirds of the genus ''Rhipidura'' in the family Rhipiduridae, native to Australasia, Southeast Asia and the Indian subcontinent. Most of the species are about 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 close relatives of the fantails. Description 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.Boles, W.E. (2006).

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rennell Fantail
The Rennell fantail (''Rhipidura rennelliana'') is a species of bird in the family Rhipiduridae. It is endemic to Rennell Island (Solomon Islands). Its natural habitat is subtropical or tropical moist lowland forests. Description The plumage is mostly mouse-brown, while the color of throat is somewhat paler. There is a reddish stripe on the wing. The long tail, which the bird often spreads, is with a pale fringe. Avoids open spaces, preferring forest (mostly virgin ones). This is the only fantail on Rennell Island. The usual sound is piercing and squeaky.: photos, description and range map Taxonomy Rennell fantail (''R. rennelliana'') forms a superspecies with: * Brown fantail (''R. drownei'') * Makira fantail (''R. tenebrosa'') * Streaked fantail (''R. verreauxi'') * Kadavu fantail (''R. personata'') * Samoan fantail (''R. nebulosa'') References Rennell fantail Birds of Rennell Island Rennell fantail The Rennell fantail (''Rhipidura rennelliana'') is a species ...

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Rictal Bristle
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened bills of bi ...

Black Thicket Fantail
The black thicket fantail (''Rhipidura maculipectus'') is a species of bird in the family Rhipiduridae. It is found in the Aru Islands and New Guinea. This species is one of 47 in the genus ''Rhipidura''. Description This is a medium-sized, long-tailed bird measuring 18-19cm and weighing 18-19g. The plumage is blackish with white spots on the chest and wings and a white tip of the tail. There is as well a short white stripe above the eye and white spot on the side of the neck. The tail is often upturned and fanned out. The iris is dark brown, the beak is black with pinkish underside. Males and females are similar but females have fewer spots and more pale abdomen. Juveniles are sooty black all over except for an indistinct white supraorbital spot and white tips on the tail feathers. Black thicket fantail is similar to White-bellied thicket fantail (''R. leucothorax''), but the last is differed by its white breast (which is reflected in its name).

The sooty thicket fantail (''Rhipidura threnothorax'') is a species of bird in the family Rhipiduridae. It is found in New Guinea.
