Thanks everyone for the helpful discussion and sorry for my silence (busy with 
life). Here’s a bit more information. First of all, I’ve added a few more 
photos, of even worse quality :-/  Here’s an updated link …

To recap, with a bit more detail. I first heard the bird vocalize, and to me it 
sounded like a completely classical red-tail sound. I quickly located the bird 
with my naked eye (90% sure it was the same bird). I did not see any other 
raptors or TVs in the area. I stepped inside the garage to grab binoculars from 
the car (15 secs or so), quickly relocated the bird and began observing, still 
assuming “red-tail”. What I noticed first was the dark underside. I observed 
through the binoculars for a few minutes before asking my wife to go grab my 
son’s camera. As I continued watching, it vocalized again. Up until this point, 
I was still certain it was an unusually dark red-tail. I thought that I saw red 
on the upper side of the tail a few times, but I’d put about 50% confidence on 
that statement.

When my wife brought the camera, before I began taking pictures, my view of the 
bird was blocked momentarily by some trees. When it emerged from behind the 
trees I began snapping pictures. I’d say I’m at least 90% sure that the bird I 
was observing through the binoculars, that I heard vocalizing, and the one I 
got pictures of are the same bird. I’m 99% sure there was only 1 bird in the 
area while I was snapping pictures. I.e. they are all of the same bird, 
including the one that looks like the tail is reddish.

I’ve seen broad-winged hawks (though not dark morph), and I’m nearly certain it 
was not a broad-wing. The wings and tail seemed too long to me and the shape 
and flight style just didn’t seem right either. The vocalization sounded 
nothing like the recordings I’ve heard of broad-wings. I’ve never seen a 
zone-tailed hawk, but that does seem to be the one that matches best with what 
I saw. I don’t recall that I ever saw it flap, but I do remember thinking that 
it held it’s wings in a slight V and that there was something else about the 
way it flew that seemed “different” (helpful, right? I know). The vocalization, 
however, sounded more classical red-tail than the recordings I’ve heard of the 
zone-tailed hawk.

Afterward, I was very sorry I didn’t have a better camera and that the 
autofocus had done such a poor job on so many of my shots. I thought I’d taken 
plenty that I’d have multiple good ones to help with the ID.

Based on the comments and my own looking at photos, listening to sounds, etc. 
I’m leaning pretty strongly toward zone-tailed hawk, but would love to hear any 
further comments.
