This year I saw the first Wood Ducks of the year in Eliza Howell Park in Detroit on March 7. A few Wood Ducks always arrive in March and spend the breeding season in the park. But in all these years I have not yet found one of their nests.
Maybe this year!
Note: All the bird photos here are from Margaret Weber.
In the last ten years I have kept a record of the active bird nests that I find in EHP. I have located the nests of 38 different species, several nests of many of them. But no Wood Duck nests, even though I annually see at least one female with young in the summer, evidence that they are breeding here.
Wood Ducks get their name from the fact that they nest in trees, in cavities. Their nests are usually in woodlands near ponds and rivers. Eliza Howell is a good location for them, with the river running through a woodland that has many old trees with natural cavities.
The male is striking.
And the female, more subtle, is likewise very attractive.
I usually find bird nests by watching birds (1) building nests, (2) on or entering nests, or (3) taking food to young in nests.
Wood Ducks (1) do not build a nest; they find a hole in a tree that is suitable and line it with nothing but some the female’s own down. They (2) enter the nest very seldom. The female lays one egg a day until the large clutch (perhaps 8 – 10 eggs) is complete and then begins to incubate them, leaving the nest very little. They (3) do not feed the young in the nest. All the eggs hatch at about the same time and, when the ducklings are one day old, their mothers calls them and they climb out of the cavity and drop to the ground (sometime dozens of feet) and follow the mother to water.
So it is understandable that their nest is difficult to locate. I think my best chance may be when they are selecting the nest site, when the male accompanies the female as they check out possibilities. Two are easier to see than one.
While Wood Ducks are regulars in the breeding season, they are not present in great numbers. My best estimate is that, in any given year, there are only 2 – 3 breeding pairs in the park. After eggs are laid, the male is not actively involved in caring for the young, as is typical of duck species. The female does not feed the young; she watches over them as they eat on their own.
The male spends the summer on his own or with other males.
Because they are cavity-nesting birds, Wood Ducks will sometimes use bird boxes. In late 2018, thanks to the efforts of several friends of Eliza Howell, three Wood Duck boxes were installed in the park. Ducks did not use any of them in the first year, 2019, but they are now providing additional cavities near the river.
The Wood Ducks have returned and I renew my quest to locate a nest.
Maybe this will be the year.
I say this every year, but 2020 just might really be the year!
