Description

Wilson's bird-of-paradise is rather small. Males can reach a length of (21 cm including central rectrices) and a weight of 53–67 g., while females can reach a length of 16 cm, but a weight of 52–60 g.Frith, C. & Frith, D. (2017)

pattern on it. The female is a brownish bird with a bare blue crown. In the field, the blue bare skin on the crown of the bird's head is so vivid that it is clearly visible by night; the deep scarlet back and velvet green breast are lush, the curlicue tail gleaming bright silver.


Diet

Their diet consists of fruits, insects, arthropods, and other small invertebrates.


Rituals of seduction

Males of these birds clear an area of rainforest to create a 'display court'. Then they perform an elaborate mating dance to impress a potential mate. The male usually exhibits an attractive breast shield and accompanies the mating dance with song and calls.


Courtship behavior

Male Wilson’s birds-of-paradise
are the most colorful of all the species within the family, possessing a veritable rainbow of color. This remarkable example of hue and iridescence possesses all of the primary colors (and more) in different ways. The baby blue hue of its head is skin, not feathers, and is the result of structural color absent in any other member of birds-of-paradise. Yellow on the nape of its neck, followed by the crimson on its back are consistent, pigmented colors, present year-round. Its quirky, "handlebar-mustache-shaped" tail feathers are brilliantly iridescent, reflecting light to produce intense color to the eye of the beholder. The sexual dimorphism of the species leaves the female very drab in comparison. Sexual dimorphism, or the difference in physical appearance between the sexes, is the result of female selection, in which females select males based upon indirect genetic benefits which increase offspring fitness. Because this species is polygynous, where one male mates with multiple females, the female is left on her own to raise young, forcing her to assess these indirect genetic benefits through courtship rituals, details of which are in the following section. Dance While these birds are difficult to locate in the wild and have not been studied in-depth, footage of the few mating rituals that have been witnessed for this species tells all. This species territorially defends a "court" in which it performs its vocalizations and physical maneuvers. Males will continually work to keep this area free of debris, making sure that nothing on the ground will distract from their displays. Males will perch on a vertical branch in the middle of their court, flexing their brilliant green fluorescent collar and calling out to females to attract them to their site. Females who are interested will perch above the male on the branch and watch as he weaves back and forth, calling to her and flexing the fluorescent collar
As was recently discovered
when researchers filmed the dance from the female's perspective, as the male displays, he is basically a brilliant green disc, and the inside of his mouth is fluorescent, making him an astonishing beacon of brilliant color. This phenomenal display of color demonstrates the power of female sexual selection over male appearance and behavior in the animal kingdom.
