So glad to have found this post and hope we can resolve what this bird is. Just this morning, I saw a large group of these birds feeding on my neighbors grass. I was amazed by their bright yellow beaks - I have never seen this bird before. I thought they looked to have a plump, large quail type body but I am not a birder. Since they were in such a large group, I thought perhaps they were migrating south. I took this photo through my window, which I have enlarged, so it\'s not the best quality. I\'m wondering if the center bird with the black head could be a male and others had a more spotted back - either females or young birds? I\'m thinking this is the same bird that the others have seen in earlier messages. Would love some feedback.
