The male has an iridescent yellow-green breast shield, elongated black plumes, three erectile spatule head wires behind each eye, coppery-bronzed nasal tuft feathers and long, wedge-shaped tail feathers. The female is a rich brown bird with blackish head. It is approximately 43 cm long. Little is known about its life and habits. The male is polygamous and performs a spectacular courtship dance in the forest ground. The clutch probably contains 1, maybe 2 eggs. These are about 40 x 26 mm and have a pale cream base color.

At the nest, they perform bill clattering activities that are typical of many species in the Ciconiidae. In captivity, another courtship display has been observed in which both partners face each other on the ground or on the nest, extend their wings outward from the body, and bow to each other repeatedly. This display continues until the male approaches the female and attempts to copulate with her, although copulation does not actually follow from most such displays. This display also sometimes continues when breeding is"
"Courtship display A courtship display is a set of display behaviors in which an animal attempts to attract a mate and exhibit their desire to copulate. These behaviors often include ritualized movement (""dances""), vocalizations, mechanical sound production, or displays of beauty, strength, or agonistic ability. In some species, males will perform ritualized movements to attract females. The male Six-Plumed bird-of-paradise, ""Parotia lawesii"", exemplifies male courtship display with its ritualized ""ballerina dance"" and unique occipital and breast feathers that serve to stimulate the female visual system. This stimulation, along with many other factors, results in subsequent copulation or rejection. In other"
"for courtship. Head and neck feathers consist of long semi-plumes measuring up to 18 cm long that become erectile and thereby have an important function in courtships and aggressive displays. Barbs on the neck feathers also have no barbules, thus making the neck appear like a translucent net. The bill is straight, bluish grey, and lined with red. The final third along the bill length is dark maroon. The iris is lemon-yellow or cream white and the legs are purplish red. The skin of the throat and the pebbly-textured lores are orangey red, becoming deeper red during courtship. The sexes"
"they bob their heads and repeatedly opening their wings halfway. They also have the courtship ritual of touching their bills together. Courtship additionally consists of giving ""quirk"" notes and, from a distance, ""kwee-urk"" calls. Copulation can consist of the female perching perpendicularly on a branch, the male mounting her back, gradually falling backwards and to the left, until he is upside down and at a right angle to the female. This bird lays a clutch of four to seven eggs, with clutches being larger for birds in the northern part of the range. The eggs themselves are white and spotless,"

These ornaments may also be a signal of high fecundity in females. Often, males and females will perform synchronized or responsive courtship displays in a mutual fashion. With many socially monogamous species such as birds, this duet facilitates pre-copulatory reassurance of pair bonding and strengthens post-copulatory dedication to the development of offspring (e.g. great crested grebe, ""Podiceps cristatus""). For example, male and female crested auklets, ""Aethia cristatella"", will cackle at one another as a vocal form of"

Courtship starts with the male chasing the female, the two hopping together through branches, and the male bobbing its head, bowing and giving a croaking call or low whistle. It makes gliding or descending display flights with the white rump spots exposed and producing mechanical noises with its remiges. The courtship climaxes with the male – wings drooped, tail fanned and rump feathers puffed up – giving repeated metallic or whistling calls. The couples may duet, but courtship feeding has not been observed. The flimsy cup nest is built by both parents, but"

Nuptial displays may occur almost year-around in some parts of the range, increasing after young disperse in autumn, thence at rare intervals until spring when such behavior, of course, peaks. Courtship often begins with a bird, often the male, ""sky pointing"" or ""long calling"" by throwing their head back. Soaring by pairs follows, with either partner leading by or soaring opposite directions. One may swoop upon the other who responds by tilting to one side or may roll over to touch talons momentarily before separating. This may"

The main flight activity generally takes place in the morning and another peak occurs before sunset. Courtship song is produced by the male’s wing vibration and consists of pulses of tone produced at intervals of approximately 34 msec in ""D. melanogaster"" (48 msec in ""D. simulans""). In 1980, Jeffrey C. Hall and his student Charalambos P. Kyriacou, at Brandeis University in Waltham, discovered that courtship activity is also controlled by ""per"" gene.

The first is by bowing their head and torso toward the male. Seesawing, the second courtship display, involves repetitively alternating lowering and raising the head and tail. The third display is begging, which is fast-paced fluttering of wings halfway extended, followed by a high whistle.

The pair fly on a strongly oscillating path with one bird ascending while the other is descending, both calling constantly. After display, the birds land on a branch for a mating ritual which starts with locking bills, followed by the female hanging upside-down for a variable period of time, and then copulation while the male holds the female's neck.

During mating season, male quetzals grow twin tail feathers that form an amazing train up to three feet long (one meter) with vibrant colors. Most female quetzals have no ornamentation and are drab. Coloration and tail feather length in quetzals help determine mate choice because the females choose the more elaborately ornamented males.

They are fiercely territorial, and, though rare, fights do break out if one strays onto another pair's territory, but dominant displays of aggression will normally see off the interloper. Pairs mate for life. To attract a mate (or impress his existing mate) the male performs a ritual aerial display before the beginning of spring.

"Lovebird A lovebird is the common name of ""Agapornis"" (Greek: αγάπη ""agape"" 'love'; όρνις ""ornis"" 'bird'), a small genus of parrot. Eight species are native to the African continent, with the grey-headed lovebird being native to Madagascar. Social and affectionate, the name comes from the parrots' strong, monogamous pair bonding and the long periods which paired birds spend sitting together. Lovebirds live in small flocks and eat fruit, vegetables, grasses, and seeds. Black-winged lovebirds also eat insects and figs, and the black-collared lovebirds have a special dietary requirements for native figs, making them problematic to keep in captivity. Some species"

The King of Saxony’s occipital feathers or “head wires” are one of a kind as they no longer possess their regular feather structure, but instead are eye-catching ornaments that possess no functionality. These feathers can be twice as long as the body of the male King of Saxony, and have evolved as the result of female selection, in which females select males based upon indirect genetic benefits which increase offspring fitness. This process occurs"

Males arrive first and begin the building of the nest, where they display to attract females. During courtship, the male employs a stretch display and uses erectile neck feathers; the neck area may swell. The female risks an aggressive attack if she approaches too soon and may have to wait up to four days. In colonial species, displays involve visual cues, which can include adopting postures or ritual displays, whereas in solitary species, auditory cues, such as the"

In the courtship display, males rapidly raise and depress their head feathers, uplift, open and close their tails like fans, and call in soft tones quite distinct from their usual chatter. The loose feathers of the flanks are brought over the primaries, and the shoulder patch is spread so the white is conspicuous, presumably to attract females. Short buoyant flights and chases follow. Magpies prefer tall trees for their bulky nest, firmly attaching them to a central fork in the upper branches. A framework of the sticks"

During courtship, mated pairs of many bird species touch or clasp each other's bills. Termed billing (also nebbing in British English), this behavior appears to strengthen pair bonding. The amount of contact involved varies among species. Some gently touch only a part of their partner's beak while others clash their beaks vigorously together.
