My suburban lot attracts butterflies, birds, frogs, lizards, raccoons, and at least 6 different species of hummingbirds (many have been banded). And not one of my neighbors would ever have a reason to complain. Some people are just over the top.
RE: Homeowner fights for a yard she calls a habitat and Houston..
I love attracting most kinds of wildlife into my yard too, but I draw the line at snakes and racoons. Where I live, the yards around mine could become overgrown if I didn't complain once in awhile, so I do. It just looks so much nicer to see plants and flowers, even if they're everywhere in a yard, than just plain weeds.
