Transcript of Future of the Hummingbird

Future of the Hummingbird
Deforestation
One limiting factor that could affect the hummingbird species is deforestation. The hummingbird uses a lot of energy flying, finding mates, and searching for food. To supply their constant activity, they need lots of nectar, pollen, food, water, etc (these are all limiting factors). If their habitat was being destroyed, the limiting factors would decrease, which means the carrying capacity would decrease,which would cause a decline in the size of the hummingbird species' population. For this species to evolve and become fit enough for their new environment they could have to evolve so their size is even smaller. The bigger the animal the more energy it requires to survive. The hummingbird species would also have to adapt to decrease wing speed. The constant 80 flaps per second requires a ton of energy which wouldn't be available in an environment undergoing deforestation. They would be required to adapt to begin eating a more abundant food source that would provide more energy to keep their species from starving and going extinct. After these possible adaptations, as an effect of deforestation and decrease of limiting factors,the future hummingbird would look smaller and fly slower.
Climate Change
If there was a climate change, for example say the temperature dropped extremely low for a long period of time and covered the hummingbird species' habitat in a white blanket of snow, how would the humming bird have to evolve and adapt to be fit enough for their new environment? *The hummingbird species would have to find a way to gather nutrients to not starve*. There wouldn't be an abundance of food for the hummingbirds, therefore the carrying capacity would decrease. This would mean that the hummingbirds would have to compete with each other and other species in order to survive (they would struggle to exist). This would cause only the fit enough of the bird species to survive and thrive in their new environment. The hummingbird species would also have to adapt and evolve so they would blend in with the snow in their environment. Today the hummingbird is a very bright, colorful animal and in the white snow, it would be extremely easy to hunt which would cause the hummingbird species' population to decrease and possibly go extinct. After a possible abiotic (nonliving) limiting factor change (climate), the hummingbird species would evolve to be a white color and adapt in many different ways.
Increase in Hummingbird predators
Another change in limiting factors would be if there was an increase in hummingbird predators. Because of the increased predators, the carrying capacity would decrease causing the hummingbird population in that area to decrease as well. In order to be fit enough for their new environment and not go extinct , the hummingbird species would have to adapt and evolve. One adaption that could occur (over millions of years) would be the hummingbird species becoming bigger and evolving so they are able to protect themselves from harm. Their species could evolve to protect themselves by developing razor sharp spikes on their feathers. With this adaption, when predators tried to eat the hummingbirds, it wouldn't be a pleasant experience causing their predators to learn that hunting the hummingbirds is a very bad idea. This would cause the predators to hunt another species, which would cause an increase in the hummingbird species' carrying capacity and population. After this possible biotic limiting factor change of an increase in predators, the future hummingbird species could have razor sharp feathers.
Future Hummingbird Species
Hummingbirds are very special and highly adaptive species of bird and are destined for further evolution. Hummingbirds are small, colorful birds. They are the only species of bird that can fly left, right, up, down, backwards, upside down, and forward. Not only can they fly in crazy directions, their wings flap so fast-eighty times per second-that they make a humming sound which gives them their name. However, these traits may change due to the following possible limiting factor changes. So, will the hummingbird evolve to be fit enough for its environment or will it go extinct?

As you can see the humming bird is a very special and unique species. These possible limiting factor changes: increase in predators, deforestation, and climate change, show how the hummingbird species could and will evolve in the near future.
