Head of a male Necropteryx. Specific to males, this curious appendix is actually an outgrowth of the bill, more or less visible depending on the social status of the individual in the horde. This determines the amount of growth hormones secreted, and determines the size of this "external sign of social class."

Systematics: Aves (Bird), accipitriforme (diurnal raptor), Accipitridae (group eagles, vaurours, kites, vultures, ect.).

Etymology: From the Greek "Necros" death, "pteryx" wing or extension bird. "Gigeri" in honor of the Swiss surrealist painter Hans R. Giger (1940-2014), inventor of the "Alien" monster (xenomorph) and science fiction horror.

Cousin of the XXI Century: The bearded vulture (Gypaetus barbatus), aka "the cleaner the mountain" or "bone-breaker" a typical vulture nourishing itself exclusively on bones it drops in flight to draw the marrow from them.

Height: 1.50 meters for females and 1.80 for males.

Distribution: All sub-desert area Eurafrique.

Tangles in Savannah: a female Neopteryx the scavenger (left) wants to cut corners and take the place of Tyrannornis (right), who strikes: Necropteryx have to wait.

Morphology: This vulture of the future, exclusively terrestrial, retains the diet of its cousin of the past (as well as its stomach containing powerful digestive juices). Its wings are no longer visible, but persist in skeletal form. This scavenger has a powerful and elongated "toothed" beak, an effective tool both for butchering carcasses and crushing bones. The upper part of the nostrils, swollen, houses a nasal gland: it is used to detect carrion from long distances away. Sometimes, when visiting mangroves, it will feed on the occasional bodies of male Velocipterus acrobatus that accidently died while flying acrobatically through the aerial roots of the mangroves while trying to display for females.

Ecology and Ethology: These scavengers live in organized packs consisting of different biological families. Excellent walkers, they can travel tens of kilometers a day in search of a carcass. It is not uncommon that it addresses isolated prey, sick or hurt. Unique among birds for the future, each female of the horde lays two to three eggs in the same dead body of another animal. The body serves as a nest that the rest of the horde jealously guards from other scavengers, until the eggs hatch. The growth of their youth is quite fast and will engage in frequent fighting to win the supreme status of pack leader.
