How do mallards mate

The dads usually stay on for about a week and a half in case the eggs get ravaged by some predator or are somehow destroyed.

Then they mate with the girl again. We aren't the only ones who have pondered these questions. There is a whole book about such things, titled "Dr. Tatiana's Sex Advice to All Creation. Publishers Weekly said of it: "readers intrigued by the bizarre facts surrounding animal whoopee and really, who isn't?

A dog was injured at the new West Allis Dog Park after cutting its paw on a piece of glass. Check out these 6 cheap or free indoor and outdoor ice skating rinks in the Milwaukee suburbs.

This ministry has an answer. Subscriber exclusive. This is partly to provide the hen with undisturbed feeding time but also to defend the male's paternity. Unpaired males will vigorously attempt to mate with unguarded females, and despite the best efforts of paired drakes, genetic analysis has shown that many broods contain ducklings sired by different male parents. Thus, we can perhaps add promiscuity to the range of mating opportunities sought by male mallards—and females, too.

As nesting proceeds, the male becomes less and less attentive until he finally abandons his mate about the time she begins incubating. At this time, the drake will strike out in search of other breeding opportunities, leaving the female to hatch and raise her brood on her own. Meanwhile, the drake may pair up with another female that has lost her nest or mate. The propensity of mallards to form new pairs within a single breeding season can be thought of as a form of serial monogamy.

Most other ducks demonstrate similar patterns of monogamy, although pairing in diving ducks, for example, typically occurs during spring migration or after the birds have arrived on the breeding grounds. And while most ducks pair and nest as yearlings, many don't breed until their second or third year of life. Remarkably, some species such as Barrow's goldeneyes and buffleheads reestablish pair bonds on the wintering grounds with mates from previous years.

Canada geese are different. Pairs will typically remain together throughout the birds' lives. But this isn't absolute. In some cases, Canada geese will seek a new mate while their former mate is still alive. This typically occurs when one member of a pair is injured or becomes lost during migration or on the wintering grounds. She conveys her commitment by following the male, bobbing her head and pecking him.

The male turns his head away from the female, now confident that the gesture will indeed entice her to follow him. At the breeding grounds, the male selects a nesting range, which he will defend against other pairs. The female picks out a specific nest site. Instigated with head bobbing by either the male or the female, the pair will mate, often several times a day, while swimming.

Often, early in the spring in the Southwest, the female begins building her nest while the male waits nearby. Typically, she digs in moist soil to form a shallow bowl-shaped nest, lining it with nearby litter and camouflaging it with surrounding vegetation.

After she lays her eight to twelve eggs usually cream-colored to grayish to greenish without markings and begins incubating them, she plucks down from her breast to add to the nest lining. Meanwhile, the male abandons the family.

Given the opportunity, the adulterous fellow may establish a new relationship with another female. Within a day after her eggs hatch, about three to four weeks after she has laid them, the female herds her young charges to water, where she will teach them the business of being a mallard duck. Within a couple of months, she will watch the ducklings take wing, headed for independence.

Normally, she will not raise more than one brood in a season. The males decide which females they want to impress, but the final decision is left to the female. Typically, a female will select the male duck that appears to be the healthiest and most capable of survival. They also desire a strong male to defend them against all the single male ducks that are still roaming in search of a mate.

Domesticated ducks will also choose their mate if more than one male duck lives in their enclosure or on the property. The same rules typically apply, although the male will probably be bonding with more than one female duck. Nature has allowed for females ducks to be more selective of their mate. Yes, you heard that right! Therefore, female ducks have to be more relaxed with the male ducks they want to breed with, to provide easier entry and a welcome environment for successful reproduction.

This means that if the interaction is not wanted or the male is too eager, he will think he has completed the task, but his sperm will likely not reach a single egg! Technically, ducks can begin mating with one another when they reach 4 months old but sometimes it takes longer depending on the breed and the specific duck. Once a female duck begins laying eggs, she can begin successfully mating with a male duck. For backyard farms, the right male-to-female ratio of ducks to have depends on the breed of the duck.

For larger breeds like Muscovy and Pekin, you should keep a 1 male to no more than 5 females. Smaller breeds like the Indian Runner, Khaki Campbell, and Mallard ducks can be successful with a larger ratio, around 1 male to every 10 female ducks you own. Sticking to the right ratio of males to females on your farm is not only important for the fertility of your flock, but also for the safety of your females. The mating process can be violent, and females receive the brunt of any injuries that occur.

If there are a limited number of males on your farm, then the females should be fine. If you keep too many males that have access to all the females, the ladies can be mated multiple times by multiple male ducks, which has been known to be fatal in some circumstances.

Females will produce eggs even if there is no male around.
