Well not being any kind of experienced bird person, I'm going by childhood and regional knowledge, I'm 61 years old and i was always told these were sparrows by grandpa (other birds on trailer, I'll get better pics of them and post later), in my humble opinion I'm 98% sure ALL the others are sparrows, i think the green that C.Spencer refers to (really bad phone pic) may be the sunflower heads i pull off to feed them, i estimate the flock near me at around 75 - 125, they fill the trees. The thing that threw me was i did not see it's red coloring till it faced me, the picture seems to be brightening the redness, it is much more subtle to the naked eye. also he is solo, no others have been sighted, perhaps he hangs with them for lack of same species company :). thanks again
