What happens when a Drake moult?
This moult results in the eclipse plumage which gives the male (drake) a much duller plumage similar to the female (duck).
What is the difference between a Drake and a duck?
Generally it is the male (drake) that has the colourful plumage while the female (duck) has a more duller and drab appearance. Although it should be said that some Southern hemisphere duck species have a similar plumage between the two sexes.
What is eclipse plumage and why does it matter?
After writing about Gadwall and Mallard last week I wanted to tell you about something called eclipse plumage. In spring ducks require their colourful plumage to attract a mate during the breeding season. After the breeding season the male begins to moult, replacing the old worn out feathers with new ones.
What is an eclipse?
An eclipse occurs when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. Let’s learn about the two types of eclipses on Earth.
What is an eclipse male duck?
Eclipse plumage, typical of ducks but found in other birds as well, is dull, female-like plumage worn by the male for a month or more in summer after breeding. It “eclipses” his usual bright plumage.
What is the purpose of eclipse plumage?
To provide some protection, particularly for the brightly-coloured males, the moult starts with their bright body feathers. These are replaced by dowdy brown ones, making them look much like females. This eclipse plumage is why in mid-summer, it seems as though all the drakes have gone.
Do male mallards change plumage?
The male Mallards have molted, dropping their bright green, reddish, black, and white feathers, and replacing them with mottled brown ones. Changing into more subdued colors for the months of summer, helps camouflage the male ducks, protecting them from predators.
Do ducks lose their flight feathers?
The manner in which waterfowl molt their flight feathers, or primaries, is unique among birds. Most birds undergo a "sequential molt," in which their flight feathers are lost one at a time from the innermost primary feather to the tip of the wing.
How long does it take for ducks to molt?
two weeksThe best part of a ducks molt is that it takes only two weeks. Chickens take FOREVER to molt – sometimes months.
Where do male ducks go in the summer?
They gather on permanent wetlands that have both emergent vegetation (where a flightless duck can hide from predators) and abundant, high-protein food (to facilitate rapid regrowth of flight feathers). These areas allow adult males to safely make it through one of their most vulnerable periods.
What is an eclipse male mallard?
Eclipse Mallard Identification After the breeding season, male mallards enter a period of eclipse plumage when they are molting their old feathers. When their primary feathers are molting, they are largely flightless and tend to be very reclusive.
Can male ducks change gender?
The dominant sex in ducks of all species at the time of hatching is male. Don't expect your male duck to turn into a female. Furthermore, males don't have ovaries, unlike females. Therefore, males can't experience gender change due to hormonal changes that make females experience gender change.
Do ducks mate for life?
Ducks do not form long-term pair bonds, but instead form seasonal bonds, otherwise known as seasonal monogamy, in which new bonds are formed each season. Seasonal monogamy occurs in about 49 percent of all waterfowl species.
Why do ducks eat their own feathers?
Overcrowding. Overcrowding can precipitate feather pecking and cannibalism. It is important to provide adequate space for each member of the flock to eat and drink. Failure to do so can encourage competition that may lead to cannibalism and cause more-dominant birds to keep others away from feed and water.
Why do ducks pull each others feathers out?
A: Pecking, also called picking, is almost always the result of high stress levels. When that happens, the birds will sometimes pluck each others' feathers out, and can really hurt one another. Those lowest in the pecking order may have bare spots on their backs or their heads.
Why do male ducks pull out their feathers?
During the nuptial molt, only the body feathers are shed. This is when the drakes get their attractive bright feather color back so the females can better decide whether they'll make a worthwhile mate. From there, they'll pair up and eventually migrate back north to their spring/summer nesting areas.
At what age does a male mallard duck change color?
At 3 weeks, the ducklings' feathers begin to grow, especially around their tails, and their yellow feathers fade to brown. After two months of feeding and growing alongside their mothers, the male and female ducklings' feathers are fully brown, resembling their mothers' in appearance.
How can you tell a male mallard from a female?
Male Mallards have a dark, iridescent-green head and bright yellow bill. The gray body is sandwiched between a brown breast and black rear. Females and juveniles are mottled brown with orange-and-brown bills. Both sexes have a white-bordered, blue “speculum” patch in the wing.

What is the name of the eclipse that occurs when the Moon is farthest from Earth?
The Sun appears to have a dark shadow on a small part of its surface. Annular (an-yə-lər) solar eclipse: An annular eclipse happens when the Moon is farthest from Earth. Because the Moon is farther away, it seems smaller. It does not block the entire view of the Sun.
What happens when the Moon orbits Earth?
Sometimes when the Moon orbits Earth, the Moon moves between the Sun and Earth. When this happens, the Moon blocks the light of the Sun from reaching Earth. This causes an eclipse of the Sun, or a solar eclipse. During a solar eclipse, the Moon casts a shadow onto Earth. There are three main types of solar eclipses:
What does the Moon look like during a total lunar eclipse?
During a total lunar eclipse, Earth blocks sunlight from reaching the Moon. Earth casts a shadow onto the Moon. The Moon can look reddish orange.
How long does a partial lunar eclipse last?
What people see from Earth during a partial lunar eclipse depends on how the Sun, Earth and Moon align. A lunar eclipse usually lasts for a few hours.
Why do scientists use solar eclipses?
Scientists use solar eclipses as an opportunity to study the Sun's corona. The corona is the Sun's top layer. During an annular eclipse, NASA uses ground and space instruments to view the corona when the Moon blocks the Sun's glare. Remember, never look directly at the Sun: Doing so can permanently damage your eyes!
What makes the Moon red?
This makes the Moon appear red to people on Earth. Earth's shadow passes in front of the Moon until it turns red or orange. A partial lunar eclipse happens when part of the Moon enters Earth's shadow. In a partial eclipse, Earth's shadow appears very dark on the side of the Moon facing Earth.
How does the Moon move?
The Moon moves in an orbit around Earth. At the same time, Earth orbits the Sun. Sometimes Earth moves between the Sun and the Moon. When this happens, Earth blocks the sunlight that normally is reflected by the Moon. (This sunlight is what causes the Moon to shine.)
