Bird species in decline all over the world

Some really worrying news from Britain. According to an article by The Telegraph some of Britain’s well known birds are in danger of dieing out. The species that have seen a dramatic fall in their populations are cuckoo, turtle dove, grey partidge and corn bunting, but there are reports saying that bird species all over the world are threatened.
The main reasons for this is believed to be agriculture, logging (habitat destruction) and invasive species.
Birds can also be seen on as barometer of how the state if the nature really is. Declining bird populations is a really bad sign about the state of the nature in general.

I hope we are able to stop this decline as birds are a very important part of the nature. Just think about going for a walk in the woods without hearing any bird chirps. That would be a very sad day.
