Hooded Merganser  Supreme Underwater Eyesight

This Hooded Merganser

is the only in its genus which is called Lophodytes? The genus name comes in its Greek word Sophos which means crest, Greek, and duties meaning diver. It is an appropriate description of the small diving duck that has a prominent fan-shaped crest.

 Bluebird Meaning It is believed that the Hooded Merganser is the smallest of three North American merganser species (the other two are Common as well as the Red-breasted) It is also the only one to breed solely on the

continent of North America. A male “Hoodie” in breeding plumage is a striking sight, with a snow-white, fan-shaped crest bordered in black; black-and-white-striped chest and back; bright yellow eyes; and rust-colored sides. Females and young animals have brown skin with a tawny hood as well as dark eyes.

As with other diving birds such as the Common Loon and Atlantic Puffin, the Hooded Merganser is a “sight feeder,” that is capable of detecting and hunting aquatic prey with eyes that are specially designed to provide sharp underwater vision. The latest research regarding eye structure Hooded Merganser eyes

shows how they alter shape to compensate for the reflection of light below the surface of the water. Eye muscles that are strong enable these birds to regulate the curvature of their corneas and lens (on the

opposite, we only manage how their lens curvatures change). This allows for equally clear vision, both above and below the water. Clear-cutting membranes (third eyelids) can also shield the eyes of birds, just as the goggles for swimming will.

North American Native

Similar to Wood Duck, like the Wood Duck, Hooded Merganser is closely associated with the forested wetland habitats. In the breeding season, the bird is particularly prevalent in and around the Great Lakes, although it is also common in other areas as well. The year-round population is spread

across two regions The first one, located in the East is located from Nova Scotia south and west up to the eastern part of Oklahoma along with northern Louisiana. Another, the smaller year-round range comprises portions of coastal and southern British Columbia, Washington state, and patches of Oregon along with

western Montana. This Hooded Merganser

is a short-distance migration, which is a southward move to stay out of harsh weather. It is winter for the majority of the Mississippi Flyway in the south-central U.S.

In contrast to the Mallard and the American Black Duck the Mallard and American Black Duck, the Hooded Merganser does not quack. Instead, it makes hoarse sounds. In Georgia, the species is often referred to as”the “frog duck” because displaying males emit a croaking, growling sound similar to the sound of a Pickerel Frog. Listen here:

A Hooded Merganser is an expert fisher-bird who uses its slender serrated bill to grab the slippery quarry. Contrary to other mergansers, that predominantly eat fish, this one adds small frogs, aquatic

insects, and tadpoles as well as plant material and crustaceans, including the crayfish. This particular merganser has a robust, thick-walled gizzard that efficiently crushes the crustacean’s hard shells.

Displaying, But Not Staying

Can Dogs Have Broccoli Many Hooded Merganser males will display before a female through ritualized displays which include showing the dazzling black and white Crest, singing, the head tossing, turning, and shaking? One of the most impressive display moves that the male rears far away from the ocean are that the fanned-crest crest touches his back.
