TRANSCRIPT
The Bald and Golden Eagle Protec2on Act protect the bald eagle. This law, originally passed in 1940, provides protec2on of the bald eagle and the golden eagle. It prohibits the purchase, barter, sale, export or import of any bald or golden eagle, alive or dead unless allowed by permit. The Migratory Bird Treaty Act is a federal law that carries out the United States’ commitment to four interna2onal conven2ons with Canada, Japan, Mexico and Russia. Those conven2ons protect birds that migrate across interna2onal borders. The Migratory Bird Treaty Act prohibits the taking, killing, possession, transporta2on, and importa2on of migratory birds, their eggs, parts, and nests except as authorized under a valid permit. The Lacy Act was passed in 1900, and protects bald eagles by making it a federal offense to take, possess, transport, sell, import, or export their nests, eggs and parts that are taken in viola2on of any state, tribal or U.S. law. Ospreys are protected by the Migratory Bird Treaty Act of 1918 and are a Washington State Fish and Wildlife Department. The Migratory Bird Treaty Act protects the falcon. It makes it unlawful to pursue, hunt, kill, capture, possess, buy, sell, purchase, any migratory bird. The Lacy Act also protects the falcons, by providing authority to Secretary of the Interior to designate injurious wildlife and ensure the humane treatment of wildlife shipped to the United States. Lastly, the Airborne Hun2ng Act prohibits taking or harassing wildlife from aircraX, except when protec2ng wildlife, livestock, and human health or safety, as authorized by a Federal or State issued license or permit.

CONCLUSION & CITATIONS
° Ospreys’ main type of prey are fish. Their eyes are specifically adapted to finding underwater prey.
° Bald eagles have a similar diet to ospreys. They eat fish as well, but they also eat decaying flesh. Ea2ng flesh causes people to think that bald eagles are scavengers.
° Falcons differ from both bald eagles and ospreys. They eats birds. Their diets mainly consists of songbirds and ducks as well as bats.
Ospreys: Clutch Size:1–4 eggs
Number of Broods:1 broods Egg Length:2.2–2.7 in 5.5–6.8 cm Egg Width:1.7–2 in 4.2–5 cm Incuba2on Period: 36–42 days Nestling Period: 50–55 days
Egg Descrip2on:Cream to pinkish cinnamon; wreathed and spoeed with reddish brown. Condi2on at Hatching:Capable of limited mo2on. Covered with down and with eyes open
.
Ospreys: Ma2ng: Once they find their mate, they’re usually mated for life, and it’s very rare that they mate again. Brood: Osprey nests are built of s2cks and lined with bark, sod, grasses, vines, algae, or flotsam and jetsam. The male usually fetches most of the nes2ng material—some2mes breaking dead s2cks off nearby trees as he flies past—and the female arranges it. Nests on ar2ficial plagorms, especially in a pair’s first season, are rela2vely small—less than 2.5 feet in diameter and 3–6 inches deep. AXer genera2ons of adding to the nest year aXer year, Ospreys can end up with nests 10–13 feet deep and 3–6 feet in diameter—easily big enough for a human to sit in. 1 brood.
Eagles: Ma2ng: believed to mate for life Brood: Bald eagles build some of the largest of all bird nests—typically 5 to 6 feet in diameter and 2 to 4 feet tall, and ranging in shape from cylindrical to conical to flat, depending on the suppor2ng tree. Both sexes bring materials to the nest, but the female does most of the placement. They weave together s2cks and fill in the cracks with soXer material such as grass, moss, or cornstalks. The inside of the nest is lined first with lichen or other fine woody material, then with downy feathers and some2mes sprigs of greenery. Ground nests are built of whatever’s available, such as kelp and driXwood near coastal shorelines. Nests can take up to three months to build, and may be reused (and added to) year aXer year.
Falcons: Ma2ng: mates for life Brood: Males typically select a few possible nest ledges at the beginning of each season and the female chooses from these. The birds do no nest building beyond a ritualized scraping of the nest ledge to create a depression in the sand, gravel or other substrate of the nest site. Scrapes are about 9 inches in diameter and 2 inches deep.
Eagles: Clutch Size:1–3 eggs
Number of Broods:1 broods Egg Length:2.3–3.3 in 5.8–8.4 cm Egg Width:1.9–2.5 in 4.7–6.3 cm Incuba2on Period:34–36 days Nestling Period:56–98 days
Egg Descrip2on:Dull white, usually without markings. Condi2on at Hatching:Covered with light-‐gray down; eyes brown; gape, legs, and skin pink.
Falcons: Clutch Size:2–5 eggs
Number of Broods:1 broods Egg Length:2–2 in 5–5.2 cm
Egg Width:1.6–1.9 in 4–4.7 cm Incuba2on Period:29–32 days Nestling Period:35–42 days
Egg Descrip2on:Pale creamy to brownish, doeed or blotched with brown, red, or purple. Condi2on at Hatching:Helpless, covered in whi2sh down, with eyes closed, weighing about 1.5 ounces.

In conclusion, the purpose of this poster was to find out how birds could be related to math. With that said, you can see that there are many ways math can be incorporated in birds. Whether it’s ma2ng, nes2ng, or speed, math is s2ll be being portrayed.
Ospreys: the flight speed for ospreys are normally 20 to 30 mph but can dive at speeds up to 80 mph. An Ospreys wingspan is between 59.1inches through 70.9 inches.
Bald Eagles: the flight speed for Bald Eagles are normally 30 mph but can drive at speeds up to 800 mph. A Bald Eagles wingspan is between 28 inches through 40 inches.
Falcons: the flight speed for Falcons are normally 40 and 60 mph but can dive at speeds up to 240. A Falcons wingspan is between 29 inches through 47 inches.

In North America, there are many well-‐known birds of prey. However, our group chose to focus on only three main birds: ospreys, bald eagles, and falcons. Ospreys are mostly found near rivers and lakes, and in wetlands and coastal marshes in North America. Meanwhile, bald eagles are found near water, such as seacoast, rivers, and lakes. Falcons are found in coastal areas, where shorebirds are likely to be, but they can also be found in deserts.
