Deathly allergic actually, but I'm honest about the reality of humans and the planet. Life we favor thrives, or life which thrives in conditions we create becomes dominant. We reshape the environment, and that includes mass settlements with pets.
Any one issue wouldn't be an issue without the others... if birds were not under pressure from every conceivable angle, any one angle wouldn't be a catastrophe. The real issue is holistic, and it is us. For birds it's habitat loss, pesticide and herbicide, hunting, poisoning, trapping, mirror-solar arrays, wind turbines, cats, etc... etc... etc...
The story is the same everywhere, and the nature of the pressure is that there are too damned many of us.
