The knob-billed duck (Sarkidiornis melanotos), or African comb duck, is a duck found in tropical wetlands in Sub-Saharan Africa, Madagascar and south Asia from Pakistan to Laos and extreme southern China. It is one of the largest species of duck. The male is much larger than the female, and has a large black knob on the bill.
Random creature concept: A self-repairing autonomous machine which survives by foraging for new parts for itself through junkyards and discarded electronics. They’re highly adaptible and intelligent when it comes to improvising new parts and components, and often even improve upon their own design and machinery when making replacements. Having no other purpose nor goal than to perpetuate their own existence, these creatures could be considered an artifical life form.
Whenever they are not in the need of repairs or in search for energy sources - most of them are solar-powered, though some have adapted themselves to other sources of electricity - they seem to play and rest. And sometimes when they have no need for repairs for their own bodies, but come upon an ample supply of potential parts, they start building completely new specimen of their own kind - much like any organic animal would instinctively find it sensible to reproduce when food sources are plentiful and there are no predators around.
