North American comb duck (SciiFii)

The North American comb duck (Sarkidiornis ohioensis), also known as the northern knobbed duck and the northern knob-billed duck, is a species of duck, most closely related to the South American comb duck (Sarkidiornis sylvicola), that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, wetlands, forests, open woodlands, lakes, rivers, and ponds across North America to help boost biodiversity. The North American comb duck is unmistakable. It is one of the largest species of duck. Length can range from 56 to 76 cm (22 to 30 in), wingspan ranges from 116 to 145 centimeters (46 to 57 inches) and weight from 1.03 to 2.9 kg (2.3 to 6.4 lb). Adults have a white head freckled with dark spots, and a pure white neck and underparts. The upperparts are glossy blue-black upperparts, with bluish and greenish iridescence especially prominent on the secondaries (lower arm feathers). The male is much larger than the female, and has a large black knob on the bill. This duck feeds on vegetation by grazing or dabbling and to a lesser extent on small fish, invertebrates, and seeds. North American comb ducks often perch in trees. They are typically seen in flocks, small in the wet season, up to 100 in the dry season. Sometimes they separate according to sex. North American comb ducks nest mainly in tree holes, also in tall grass. They line their nests with reeds, grass, or feathers, but not down. Males may have two mates at once or up to five in succession. They defend the females and young, but not the nest sites. Unmated males perch in trees and wait for opportunities to mate. Females lay 8 to 16 yellowish-white eggs. Several females may lay in a single "dump nest" containing up to 50 eggs. The conservation status of the North American comb duck is Least Concern due to successful conservation efforts, the North American comb duck's wide range and its tolerance to many of the human activities.
