I read recently an article about how many millions of birds are getting killed by USDA every year. They poison them. Check the list out: list of killings by USDA. Page related to bye bye blackbird article.
What is unfair is that WE allow this to happen! In times when climate change is affecting everyone and lots of species will die out eventually simply from natural causes humans took charge and started killing them by thousands before their time! We are not owning this planet, we are co-existing/co-inhabiting with other species. Why the killing rage? Lets learn to live peacefully with nature. So detached we are, sometimes we think that we are alone upon earth and that someone handed us the keys to the Gates and said "Here, don't let anyone or anything else in, take it all for yourself and make sure you exploit everything around you". It is not this way of course. We depend on the balanced system we call Nature it terms we cannot even realize. There is not so much scientific proof as yet as to what happens if we kill that many birds here and there. But think about it for a moment, those birds are food to someone else or they feed upon something else that is going to keep increasing in numbers having no predators and possibly cause a big hole in the system one day. It is proven, I have read somewhere that the more you kill a species, it bounces back in even bigger numbers. If that is the case then we are in big trouble either way.
Another big birds killer's area is the Gulf of Mexico with its thousands of Oil and Gas offshore platforms (around 6,000!!!). Believe it or not the birds get confused by the red light of the platform and loose orientation and die off the platform since most bird migrations take place at night and there is no sun light for birds to help orientate themselves. They have their own navigation system which is probably more complicated than we know. This problem was known since '79 see here bird killings. Recently there is someone who is fighting for a change and whom I have witnessed lecturing on the subject: Dr. Michael Fry, Director of Conservation Advocacy, American Bird Conservancy. It has been also brought to the public eye here.
How can you save them? Call up the White House and complain about the situation. Tel : 202-456-1414
Write about the situation, speak about it, communicate it any way you can. Help out! It is your kids that are going to be affected too in the future!
