The A. colubris is one of the most common species of humming bird in North America. It occupies much of Mexico, eastern/central United States, and even lower parts of Canada (All About Birds).This species is migratory. This species is also an essential keystone species. In an ecosystem there are multiple keystone species. These species are vital to the balance of life, food, and new species management. A keystone species shapes the environment for all of the animals in the ecosystem. A keystone species can accomplish this in a variety of ways. It can either create a burrow for itself and other animals can use that space. An example of this is the alligator. Another way keystone species help the ecosystem is regulating the population of other species. An example of this would be a wolf. Without species like this the population would become imbalanced quickly. Another kind of keystone spices is an animal that pollenates plants. This makes sure that the plants are able reproduce and prosper. An example of a relevant keystone species would be the American honey bee. The final kind of…show more content…
That role is to regulate the amount of invasive species. If an animal did not pollenate and strengthen the population of native species invasive species would start to overrun the ecosystem. The overpopulation of invasive species is bad for a variety of reasons (Macalester). The first reason invasive species are bad is because they can negatively affect the chemical makeup of the water. A second reason that invasive species are bad is because they can alter the availability of previous resources, for other animals and humans. The final reason why invasive species are bad is because they can negatively alter the availability of food for other organisms. Invasive species also lead to stress on government. It is estimated that the global cost of invasive species management makes up five percent of the global
