A concerned citizen witnesses his neighbors toss trash across the alley and wonders whether there are limits to what Chicago city waste haulers will pick up. And an observant resident notices more hawks in her ‘hood. Is it her imagination, or are these birds of prey staging a comeback? Note: the hawk in this image is *not* to scale. It's a composite image from two Creative Commons licensed photos via Flickr by users: "Chickens in the trees" and "like, totally." Yes, those are their usernames.
