Transcript of Bald eagle

Four Abiotic Factors: Pesticides affect the bald eagles diet which come from some of the fish it eats, also this affects their ability to reproduce. Another example would be pollution which has affected a large amount of the eagles food that had been killed (water pollution). Also the hot and cold seasons depending on if there water source has frozen up they will most likely move. Lastly the distance from the sea will determine where the bird stays year round. Abiotic Factors Biotic Factors Four Biotic Factors: The bald eagle eats fish, and small mammals like rabbits and seabirds, this gives the eagle its energy. Also other birds create competition for food that the eagle has to fight for. Lastly waterfowls(Ducks, geese, or other large aquatic birds) are the bald eagles secondary foods. Scientific Name : Haliaeetus Leucocephalus For a long time bald eagles were hunted down. These amazing birds use their talons to fish, but they get many of their meals by scavenging or stealing the kills of other animals. A bald eagle usually sits at the very tops of trees and feed on the fish in the water below. They stand three feet tall with a wingspan of over six feet. There are over 350nesting pairs in Maryland.

Food Web- A group of animals each showing what eats what, creating a cycle Symbiotic Relationships Example- Bald Eagle its a snake Energy Pyramid Bald Eagle Little Fish Algaeeeeeeeeeeeee Big Fishhhhhh Mutualism- Both benefit Commensalism- One organism benefits and nothing affects the other Parasitism- One benefits and one is harmed Examples: Commensalism-The bald eagle uses a tree to make a nest in it. Predation- Bald Eagle its a snake Mutualism- A bird traveling on a bald eagle and eating parasites off of it Predation-Eagle also eats a rabbit 1 Kg 10 Kg 100 Kg 1000 Kg Predation- When one organism eats another organism.
