The Northern Pintail (Anus acuta) is a large dabbling duck that nests in the spring between April and June. The male is easily identifiable displaying a chocolate colored head and long central tail feather. The female lays seven to nine cream-coloured eggs at a rate of one per day. Should the clutch be destroyed, the female can produce a replacement clutch, generally with less eggs then the first clutch. Incubation lasts about 23 days and upon hatching, the hen leads her brood to wetlands that have good cover and food source.
