I'm not really a bird nerd but I do love to watch the wild birds while I'm watching my hens. They are really interesting. For instance, I had no idea that doves fought! They batter each other with one wing, and their threatening posture is to hold one wing up. I have doves, cardinals, blue jays, sparrows, and my favorite - mockingbirds. On occasion I see other species like crows, starlings, and of course there is a hawk couple around. Love it when I see the crows harassing the hawks! I even saw a mockingbird run a hawk off once. I had no idea they could do that, love my mockingbirds! I have a feeder that I fill with exactly the same amount of food every day at the same time. I don't want them dependent on me for more than 1/2 cup or so of feed a day. Even that small amount attracts lots of birds though and gets them looking around the rest of the yard to supplement their diets. And sometimes I run some rice through my grain mill just to crack it and spread that around. Both the wild birds and my chickens like to find that.
