Molting is the process of replacing worn feathers. The post breeding period coincides with the time of year when insects are most numerous.ĭucks depend on their feathers and old, worn feathers must be replaced. Perhaps waterfowl select specific foods high in proteins, like bugs, based solely on their nutritional value. Protein nutrients are extremely important, especially amino acids, the building blocks of life. Nutritional stress is a situation where nutrients demanded by the body exceeds the amount of nutrients a duck is able to find and eat. Scientist speculate that the reason for there being more drake (male) mallards than female's (hens) in the population is the result of the higher deaths that occur to hens during the post breeding period.ĭuring the post breeding period ducks can experience nutritional stress. These energy-expending activities take place during the post breeding period. Mallards are required to find energy sources to fuel the activities of raising a brood, keeping themselves healthy and regrowing feathers during molt. Post breeding is the period in the annual life cycle of a duck bracked by breeding and nesting. A hen's chance of suffering from death increases when she is defending her ducklings. This is when the hen must put forth the most energy to keep her ducklings together and safe. The most important time in a duckling's life is the first two weeks of life. To keep ducklings healthy a hen must brood or keep ducklings warm until they can do it themselves, help ducklings find a good source of food, ensure family bonding as a unit and finally, guide young ducks during migration and help them locate staging and wintering habitat. This precious balance must be met to maximize both the hen's and ducklings' chances of survival. ![]() The more time a hen spends taking care of young ducklings, the less time she has to take care of herself. Although intuitive, the relationship between nest success and grassland expanse was only recently confirmed by USFWS biologists while evaluating the benefits of Conservation Reserve Program (CRP) to ducks.īrood Rearing: Taking Care of the Ducklings But suppose that the nests are concentrated in small patches and in thin strips of grass. If you are a predator searching several square miles for a meal, encountering a duck nest would seem like a long shot. Follow the life cycle diagram from breeding to wintering for a better understanding of the activities and energy requirements in different phases of a duck's annual cycle. In the space of one year a duck experiences the full spectrum of seasonal changes that usher in opportunities and challenges.
