Think mohawk or windblown or Bride of Frankenstein, and you may be able to picture the great crest of feathers atop the hooded merganser’s head. Hooded merganser crests or hoods are fan-shaped and collapsible feathers that can stand up straight or lay flat on their head. They are small ducks with thin bills, approximately 18 inches in length and weighing just over one pound. Much like the goldeneye, male mergansers are black and white with a vibrant yellow eye, and females are a more muted gray and brown.

Wood ducks are one of the most strikingly beautiful ducks in the waterfowl family. The males have unmatched iridescent shimmering greens, purples, and pinks decorating their crested heads, backs, and wings. The rest of their bodies vary in ornate patterning; their sides look like a sepia tone topography map, while their breast is the color of a mottled chestnut shell, and their wing speculum a polished sapphire. The females, while less colorful, sport an elegant gray silver head with a white accent around their eyes, their breasts like granite, and a bright shimmer of color pokes out from their wing bands. Wood ducks are one of few species whose strong claws can grip bark, allowing them to perch in trees. They are similar in size to a hooded merganser.

The preferred meal for the truly omnivorous wood duck is mostly seeds, with some aquatic plants and insects. In many parts of the country, wood ducks rely on acorns as a major source of their diet. These ducks typically dabble and only do shallow diving.

Wood ducks are also cavity nesters and they love areas that are thickly wooded or highly vegetative (like large cattail marshes and beaver ponds). Wood ducks can be spotted at Camp Polk Meadow Preserve in the cattails. Their small stature and short, broad wings make them highly maneuverable in these areas. These ducks lay nine to 14 eggs and often will lay eggs in other mother’s nests, sometimes called “dump nests,” where there is no incubation. These are some of the only ducks that will have two broods of ducklings a year (more common in southern North America than northern).

This is our smallest and most energetic diving duck with some major flare to boot. The male bufflehead’s oversized head glimmers green and purple iridescent with the appearance of a large pie slice removed, leaving a white patch on the back of its head. The rest of its body is a sleek and stark torpedo of black on white. The female is an unassuming brown and gray duck with a large head and distinctive white cheek patch. Both sexes measure around one foot in length and weigh between one half and just-over one pound.

Buffleheads are impressive divers and use their skills to catch aquatic invertebrates, insects, and mollusks as a main food source. Dives for food typically last between 12 and 25 seconds.

These small ducks choose woodpecker and Northern flicker holes as their nesting cavities, often preferring cavities found in aspen and poplars. Bufflehead are another mostly monogamous species and will stay with their partner for a few years, laying one brood of four to 17 eggs per year. Males will often leave the females during incubation in order to molt, but will return to help protect the ducklings.

Ten years ago, the United Nations General Assembly proclaimed this holiday to honor and raise awareness of the importance of all types of forests. You can celebrate by taking a walk in your favorite forest or taking action to protect the forests you love.

This United Nations holiday is used to advocate for the sustainable management of freshwater resources, as well as raise awareness for the two billion people living without access to clean drinking water.

World Aquatic Animal Day raises global awareness of the importance of aquatic animals such as mollusks, aquatic mammals, amphibians, birds, and insects. The creators at Lewis & Clark Law School hope it inspires people from all over the world to create policies, laws, education, and collaborations that will help to protect these valuable creatures.

Every year, the International Dark Sky Association promotes International Dark Sky Week to raise awareness about the negative impacts of light pollution and to celebrate the wonders of our starry skies.

First established in 1987, National Wildflower Week is a celebration of the beauty of wildflowers, and it promotes the importance of native wildflowers in our ecosystems.

World Migratory Bird Day is celebrated on different days in various countries, but in the US, it is on May 13th that we celebrate the incredible journeys of migratory birds, and commit to worldwide conservation of migratory birds and their habitats.

The United Nations General Assembly proclaimed World Bee Day to raise awareness on the importance of pollinators, the threats they face, and their contributions to society.
