Is Global Warming Killing Birds?

birdIn the article Climate Change Will Disrupt Half of North America’s Bird Species, Study Says, scientists describe how the changing climate in different parts of the world will effect 650 of species of birds in the nest 65 years. The change in climate will drive dozens of bird species into extinction because they will be unable to find a new area to relocate to. This reason alone is going to effect over 21% of bird species by 2050 and 31% by 2080.

I agree that global warming could defiantly affect the bird population in a negative way but I find it hard to believe that scientists can accurately predict what bird populations will be in 65 years. 65 years is a long time away and so much can happen in this amount of time. What if global warming doesn’t happen as quickly as the scientists believe it will? What if hybrid cars become very popular and instead of 65 years, these bird species become extinct in 100 years? There are so many different factors that affect this test that I think it is too large a time span to be so accurate.

A question I found myself asking while reading this article was “why don’t the birds just move some place else?” It’s not as easy as that. For example, a bird that is from California cannot just leave California and migrate to Washington. This is because what the bird eats in California may not be in Washington and the species will be left without food and soon die. There are many factors like this that we fail to recognize with topics such as this. Something else we have to consider when talking about this topic is “what is going to happen to the insect population when all these species of birds die off?” Birds eat spiders, misquotes, worms, ect. so we have to ask ourselves if these insect populations are going to rapidly increase with the bird population dying off so quickly. Scientists from Radbound University found that “in areas where water contained high concentrations of imidacloprid—a common neonicotinoid pesticide—bird populations tended to decline by an average of 3.5 percent annually.” This shows that there is a connection between using pesticides to kill the increasing insect population and the declining population of birds. This also brings up the topic of farms over using pesticides which will in return have a negative impact on humans and what they eat. But farmers over using pesticides can be due to a lot of different factors such as location, insects, ect. so it is hard to say that them over using pesticides is only due to the increasing bug population due to bird species dying.
