Migration and Habitat of Birds  

 

What we already know (from the book Just Cool It!)

·         Poorly situated wind farms, especially ones using older turbine technology, do kill birds, but it<s an issue that can be addressed, it’s not the biggest big killer

·         Fossil fuels, especially coal, are by far the largest energy-related bird killers.

·         Heavy metals created by burning coal kill a lot of birds and even change their songs, which affects their ability to mate and protect the territory.

·         House cats kill billions of birds per year.

·         Habitat loss is a major threat for birds.

·         Birds have an ability to warn us of incoming storms. Therefore, if their populations are lessened, we, as humans, have more difficulty to see storms coming.

 

What we learned

Migration

Birds are in danger due to increasing temperatures, flooding or desertification. Because of the desertification, many birds, during their migration, can’t rely on areas such as the Sahel region, for example, they can’t rest there due to the lack of rainfall that causes the crops to stop growing.

Birds are either migrating earlier or later than they’re supposed to, which means that they don’t arrive when the preys are most available. Therefore, if they don’t have enough food to eat, they can’t concentrate on mating and the populations decrease. Some birds also just stop migrating because of the changes in weather patterns. Since the temperature takes longer to get colder, some birds just wait around until it’s too late. Therefore, birds that are stopping their migrations are in danger, and endanger other bird species, such as the ones who are still migrating. In fact, it creates competition between bird species when many occupy the same territory, even for a short amount of time, like in migration.

Birds have to have incredible timing when they migrate. In order to do so, they have to sense the season changes by observing the light the sun gives. However, because of climate change, the weather is not matching how long the sun stays up. Their preys are based on temperature rising. Therefore, they’re only laying their eggs when it’s starting to get hot, which doesn’t coincide with the sunlight anymore because of climate change. That way, the timing of birds is off and their food supply diminishes.

 

Habitats

Since their habitats are being destroyed, birds are going to move and migrate to stay in the ideal climate. If they change habitats, the food and nesting materials they need might not be there. Also, they may face new parasites and unknown predators. The birds won’t know how to react to these new predators, which can cause the populations to decrease.

With sea levels rising, many birds who inhabit coastal areas will have no more land to lay their eggs. Moreover, the accessibility to make a habitat for themselves is decreased because of the erosion of beaches and storms surges.

With global temperature rising, invasive pests and plants may spread in other regions and destroy bird habitats by making them unfit for them. Many bird species may be affected by diseases such as malaria, transmitted by mosquitoes. For example, higher areas such as mountain tops create a shelter for birds, since mosquitoes can’t reach these areas. However, with temperature rising, mosquitoes can reach to higher areas and therefore, more birds are threatened by malaria.

I really like your article and I’m happy to learn new things. For example, I do not knot that the desertification affects bird. It’s logical, but I never think of it and also that mosquitos can reach them now on the top of mountains because the temperature is rising.I like the way you explain how climate changes affect birds. Only drawback: you repeat too much the word birds! Otherwise, I wish we going to find a way to help them around the world, but here in Quebec, we have a sanctuary for many wild animals and injured birds can also go there. Its name is Ecomuseum and they take animals in, they nurse them and by the same time people can go there and learn about the wildlife of Quebec. They prioritize the wellbeing of animals and they also think that educate kids about animals and environment will raise awareness among them so they will make better decisions for the future. Actually, Ecomuseum works to improve the Animal Care Center and the river of Otter habitat, but in the future, they want to build an aviary for mixed bird of prey. They always need help with their association because they are a not-for-profit organization. They ask for people to read stories and manage craft activities, to become naturalist guide or to participate during the summer camp. If you are interested you can contact them at 514-457-9449 or write them to info@ecomuseum.ca. For further information, you visit their website*.
