The article is fairly true ---welfare isn't really ever a good thing, it just creates dependency and increased populations of the dependent types.
This -- the bird feeder and the bird feed -- is not a paradigm of handouts, welfare and dependency.
Read up and down this thread. Notice that the people who feed birds are doing it voluntarily. Notice how the feeders of birds enjoy the show that the Chickadee, the Blue Jay, the Cardinal, Red-breasted Nuthatch and the Tufted Titmouse put on as they eat their seeds. Even the predatory Red-tailed Hawk puts on an entertaining show as he claws a plumpend chickadee.
Also notice how these birds gain from their showy activity. They get rewarded with bird seed.
The people who feed birds pay for the seeds. The birds who eat the seeds perform an entertaining show. The pattern is capitalistic -- the form is freedom....and it is the statists of the world who hate this and must stop this by writing this nonsense article. They don't want to see their beloved birds of nature become more like us -- free to better themselves.
It doesn't get better than this so feed the birds -- feed them good!
