Several resources recommend trying to mimic the natural situation (single boxes placed in swamp habitats) as much as possible to help with nest success. We artificially incubated wood duck (Aix sponsa) eggs at three temperature regimes (low, 35.0 mid, 35.9 and high, 37.3C) that are within the range of. On average, it usually takes about 28 days for duck eggs to incubate and hatch. These birds live in wooded swamps, where they nest in holes in trees or in nest boxes put up around lake margins. Males are iridescent chestnut and green, with ornate patterns on nearly every feather the elegant females have a distinctive profile and delicate white pattern around the eye. Artificial nest boxes that are placed too close together or in very conspicuous locations may lead to increased egg dumping (some reports are as high as half the nests). Incubation periods can last between 26 and 37 days. The Wood Duck is one of the most stunningly pretty of all waterfowl. Some suggest that in the wild, the impulse to egg dump is kept in check because wood ducks normally nest in fairly isolated locations. Young: ducklings remain in nest until morning after hatching. success 102 hatched nests x 11 eggs 1116 eggs x 63 egg success 703. Incubation is by female only, 25-35 days. In North America, the Wood Duck (Aix sponsa) is the most abundant species of. In a typical nest box, approximately 80% of the eggs hatch, but where egg dumping is common, it may drop to as low as 10% or the original female may abandon the nest altogether. Females frequently lay eggs in each others' nests, sometimes in 'dump nests' where no incubation ever takes place. Egg dumping occurs when a female wood duck, frequently a first-year breeder (according to some references), follows another hen to a nest site during the egg-laying period and lays her eggs in with the other nest, presumably coming back each day while the original female is away foraging to keep laying until she has finished. This results in very large clutches that often cannot be effectively incubated. This may be an example of intraspecific brood parasitism, also called “egg dumping” or “dump nesting”. The Muscovy breed is one notable exception. So, how many eggs do you see in this nest? Certainly way above the average number for a clutch. The incubation time for duck eggs can vary by breed, but on average, it takes 28 days to hatch most breeds. Normal clutch size according to many sources ranges from 6-16 eggs with an average of 12. Like most (if not all?) birds, Wood Duck females lay one egg per day until she finishes and begins incubating.
