Climate change linked to shrinking bird sizes is a serious matter today. The present-day environment is not at all suitable for the wild-life. Moreover, it is the beginning of a destructive future of Earth for which we all have to pay someday. The biggest reason for a terrified wild-life is climate change. Due to several human-made inventions, various changes took place in the environment. This, in turn, cast a profound impact on the weather conditions of a region. However, humans are not at all concerned about these damages to the environment. They are continuing their destructive activities and ruining the natural resources of the green planet. If this continues to happen, our green planet will convert into grey Earth very soon.
What Is The Reason?
This is a very significant question in the present-day scenario. With the advent of mobile phones, the number of birds is decreasing day by day. Moreover, the few birds which are present are much smaller in size than the previous ones. This is due to changes that are taking place every while in the surroundings of these poor creatures. Humans do not understand the facts that their selfish deeds are ruining the precious resources of Mother Nature. However, if now also, we can take steps regarding the same, we can leave a cleaner environment for our future generation. Otherwise, at some point in time, all the animals and birds will become extinct.
Many researchers are working on this issue to find possible remedies for such a crisis. The recent reports show that the North American birds are shrinking in sizes as the temperature rises gradually, almost year. Also, their sizes are smaller than their ancestors, who were present merely about four decades ago. This implies that global warming is harming the wild-life, especially the poor birds.
Climate change linked to shrinking bird sizes
The undergoing environmental changes are also the reasons behind the changing lifestyles. Also, we can observe several changes in the behavioral patterns of the birds. However, scientists are unable to draw any conclusion regarding the shrinking sizes of the birds. They are just predicting that changing climates can be a possible reason behind the same. Too much heat can cause hindrance in the growth of the birds.
Moreover, smaller birds get cold very quickly. So, they are unable to handle the tremendous heat. They search for shady places to take rest. Unfortunately, the increasing instances of deforestation or cutting of trees for the satisfaction of selfish needs of mankind, are creating an unsafe atmosphere for the birds and animals. Most of the birds are going into the paths of extinction. The ecologists are in high tension after observing such terrible effects of climate change. Also, to the contrary, the study of several birds revealed a lot. We find that the sizes of the wings are increasing along with decreasing the mass of the body. This can be a good sign which will improve the flying efficiency of the birds.
