Common Loon

Males are slightly larger than females, this bird is smaller than a goose and larger than a mallard duck. The bird weighs 8 to 12 pounds when it is fully grown. It has a black bill and red eyes it has a dark greenish black head and in the summer its body is black with white spots, in the winter its top is a shade of gray and its bottom is white.Slide3

Loons don’t begin breeding until three to four years old. They build their nest on the outside of reeds and grasses on the water edge. They take turns incubating the eggs and then after 28 to 30 days the chicks start to emerge, the chicks are blackish brown and take a swim not long after they hatch. Young loons don’t fly until they are two months or older. The parents will carry the chicks on their backs for protection from fish and turtle predators.Slide4

Loons eat pan fish, perch, ciscoes, suckers, trout, bullheads smelt and minnows. They also eat frogs, leaches, crayfish, mollusks, salamanders, amphipods, and insects.

Adult loons are only venerable to bald eagles, but their young are venerable to skunks, raccoons, foxes, snapping turtles, northern pike and muskies.

Loons are found on lakes in central and northeastern Minnesota. About September loons travel to their winter home along the Atlantic coast, from North Carolina to Florida or in the Gulf of Mexico.Slide5

Minnesota has more loons than all the states except Alaska. Roughly 12,000.

Human disturbance and pollutants like lead and mercury are bad for the loons and will not allow them to last very long.

Loons have no season, they are a protected bird, which means that there is no season to kill them.Slide6

Fun facts about loons

Loons will dive up to 250 feet to retrieve their food.

Loons have solid bones, unlike the hollow bones of other birds.

The extra weight of their bones helps them dive down as far as 250 feet.

Loons need a 100 to 600 foot runway to take off.Slide7

White tailed deer

Large brown or gray mammal with a white tail that lifts when alarmed or running. 4 to 6 feet long, 2 to 3 feet tall with a 6 to 12 inch tail

Males weigh 100 to 300 pounds. Females weigh 85 to 130 pounds

Snorts, grunts or bleatsSlide9

November to December, fawns are born 7 months later. Fawns have white spots that last from 3 to 4 months, remain nursing with their mother for several months. Males travel long distances in search of females during mating season, they scrape trees and patches on the ground where they urinate to tell others that it is not their territory.

White tailed deer eat acorns, corn, soybeans, mushrooms, grasses, tree leaves, buds, twigs and bark, wild grapes, apples and assorted shrubs.Slide10

Wolves, coyotes, bear, and bobcats hunt and eat whit tailed deer.

White-tailed deer live in prairies, forests, swamps, wood lots and agricultural fields.

In Minnesota there are 900,000 to 1,000,000 deer.

Hunters harvest around 150,000 to 200,000 deer a year.Slide11

Fun facts about white tailed deer

When alarmed white tailed deer fan their ears and raise their tails as though raising a white flag.

The white tailed deer's white tail raises when they are running.

They can be a nuisance to farmers eating grain they have stored for other live stock.

Male white tailed deer loose their antlers in the winter and grow them back in the late summer and early fall.Slide12
