I photographed this Coot at the Oak Ridge Marina at Melton Hill Lake in late February 2007. Note the feet on this bird. Unlike most water birds, Coots don't have webbed feet, they have 3 webbed toes. They are plant eaters and often eat aquatic plants, but they will nibble on grass and seeds on the land too. It can be a challenge to watch them as they often dive under the water.
One of the favorite activities of young children is to feed ducks. The ducks, geese, and coots in Oak Ridge are well-trained, as soon as they see people walk out onto the dock they quickly paddle up to see if they can get a handout! There is a duck food dispenser by the boat ramp where people can buy dog food pellets to feed the ducks. It is highly discouraged to feed the water fowl bread, it can cause illness in the birds.
Moscovy Duck (Cairina moschata)
I call this the "Elvis duck" because of the upswept look of the feathers on its head. It is a Moscovy duck, it sure is wild looking! The body feathers had a pretty green sheen.
Canada Goose (Branta canadensis)
Thisgoosw is showing displeasure that I am nearby. I tried to be still and quiet so I could avoid disturbing them too much. The parents dip their head up and down, crooking their neck as a signal that they are upset. In March, the geese pair off and lay their eggs. The goslings hatch in April. The babies are very cute and fuzzy, but don't be tempted to pet them, Mom and Dad will protect them; if you don't know what it means to be "goosed", you'll find out! :) Canada geese have become a problem in many areas, they don't migrate from east Tennessee in the winter. They pollute water and contaminate grassy areas and marina docks with their droppings.
Don't feed human food to ducks and geese!
I hope those french fries are trans-fat free!
Mallard duck (Anas platyrhynchos)
This male mallard is swimming in the sun, you can see the beautiful colors refracted by the feathers on his head. Note the little curl of feathers on the tail, a characteristic of some male ducks.
Muscovy Duck; Cairina moschata
This is a male Moscovy Duck, sometimes they will breed with other ducks, resulting in some really "ugly ducklings"! I did see a duck that appeared to be a cross between one of these and a Mallard. Actually, the ducklings of this type of duck is yellow and brown, they don't have the red patch of skin. Only males have the red patches, what a strange type of "makeup"! According to a website I found, these ducks are "quackless". They can be aggressive, another good reason not to feed the wildlife!
Mallard ducks; Anas platyrhynchos
This pair of Mallards was photographed at Melton Hill Lake in Oak Ridge. When the male is situated at the right angle it is easy to see the spectacular blue-green hue from the refracted light on the feathers of the head. Female mallards are drab brown, well camouflaged from predators when they sit on their nest. They (and the many other ducks and geese) didn't stick around long when the realized they weren't going to get fed! Feeding wild animals human food (bread!) is bad for their health and in some cases can be fatal.
Canada geese (Branta canadensis)
Canada Geese were re-introduced into the east TN area and they have found the lakes, ponds, parks, lawns, and docks very much to their liking. In fact, they like it here so much, they have become permanent residents (or "pests" if they mess up your yard or dock with their droppings!). In the fall they honk and will fly around in the "V," but they don't go anywhere. Researchers often tag the adult geese with large neck bands and leg bands. One of my students once found a dead goose with a metal leg band. I sent the number on the band to the address in Washington D.C., a couple of months later I received a letter telling that the goose had been banded a mile or so away! During the time the geese lay their eggs in March, they begin to molt their flight feathers. The parents are unable to fly for several weeks. They often lay a large clutch of eggs and start out with a big family. However, as the weeks pass, some of the goslings fall prey to predators such as foxes, turtles, and even large fish! This photo shows the size comparison of the Canada gosling to mallard ducklings.
This Mallard drake is "preening", or cleaning his feathers. Since ducks use their feathers for floating on the water, they have to keep them free of dirt and parasites. They must keep the feathers oiled and waterproof in order to float and stay dry. Ducks have a uropygial gland near the tail that secretes oils and waxes that the duck spreads over the feathers with its bill. Oil spills are devastating to water birds because they are unable to clean their feathers, if they try to, they eat the oil, which can be fatal.
