Human are likely the reason to be blamed for the climate change that has been occurring since the rise of the industrial revolution. As we became more advanced, we began to release and emit an enormous amount of greenhouse gases such as carbon dioxide, carbon monoxide, methane, Nitrous oxide and many others. The emission of all of these gases has contributed to many environmental effects such as an increase in the overall temperature of the earth, which eventually lead to climate change and global warming. This climate change had an effect on animal activities such as birds. Climate change has contributed to very important changes in bird’s migration patterns and their ability to evolve under the new conditions. Birds tend to migrate seasonally,

But climate change also can lead to a warmer temperature. Some birds like to mate at a cooler temperature so when the temperature gets warmer in the location that birds live in, they tend to migrate earlier than usual. When it comes to birds, they tend to time their arrival to the new place on the breeding grounds based on climate change other related environmental factors (Peter A. 2003). This is a very important key to their reproductive success and fitness. So when these groups of birds arrive too early to their new location, they will face a hard time mating since the temperature will not be their favorable one and therefore it will be survive in climates that they are not used to. This will ultimately not help the population to evolve. For example, birds such as hummingbirds are extremely sensitive to temperature. When they are force to arrive early to a place that doesn’t favor their temperature, they will be in danger of dying which will risk their reproductive success and reduce the number of the population in the long run (Gian-Reto et al. 2002). In some cases birds tend to take a longer migrating way trying to avoid places that have the risks of facing floods due to the increase of the sea level. When those birds arrive to their new breeding place too late, the chance that they mate with a high quality mate will be very slim because those high quality mates will be already taken
