. . . . . I am considering the Canon EOS 80D and 7DMK2.
I enjoy shooting wildlife, birds, and landscapes.
Most of my photography is done early in the morning or in the fading light of the evening, before or after work. Because of that, and the fact that I cannot afford to upgrade lenses to f2.8 versions I am looking for a camera that will offer usable shots at ISO 3200 and maybe even ISO 6400?
Does anyone care to offer any advice based on either their experience or that of others they know regardless of brand preference?
I know nothing about Nikon cameras, so my answer will be confined to Canon's DSLRs.
I shoot the same stuff you do, most often in the same conditions - dim light at dusk and dawn. I don't think there is any need to shoot at the super-high ISOs you mention, nor do I think there is any reason to shoot at such fast shutter speeds. Give yourself a break - it's not as difficult as you think!
Shutter speeds of under 1/100th of a second are usually plenty good enough with today's image stabilization, which is good for 4 full stops. Unless, of course, you are trying to freeze motion, such as with running deer or flying birds. But even then, you will be able to sufficiently freeze just about any motion you want to freeze at about 1/250th or 1/320th of a second, for mammals.
I am posting two photos here, to illustrate two aspects of shooting at dusk.
This photo (directly below) shows that for portrait-style images of a stationary animal, shutter speeds of under 1/100th of a second will work out just fine. The whitetail buck portrait I am posting was taken at 1/25th of a second, handheld, at 400mm. The 4-stop I.S. on Canon's new 100-400mm lens makes this possible.

I am posting this next photo to show that you don't need anything as fast as 1/500th, even to freeze motion. This running / leaping Whitetail Buck was pretty much frozen sharp at just 1/320th of a second, at 1600 ISO, at 400mm. I believe it wouldn't been just fine at even 1/250th of a second. And this is a scared deer on an all-out run!

© Tom Reichner [SHARE LINK] THIS IS A LOW QUALITY PREVIEW. Please log in to see the good quality stuff. Both images were taken with my Canon 1D Mark 4, which produces good results at ISO 1600, provided you over-expose about 2/3 of a stop more than what the meter says to do. I would not take photos with this camera at 3200 ISO - even though many other photographers think that it is "great" at 3200 or 6400, you will get some grain, especially in the dark, out-of-focus areas of the frame, and that is completely unacceptable to me. You can get a nice used Mark 4 for about $1200 bucks these days.......maybe even less. I think a 7D Mark 2 will produce the same results at about the same ISO settings.
For birds, well, shooting birds in flight is never really going to work out too well at dusk or pre-dawn, unless you are going for some artistically rendered type of look (motion blur, slhouette, etc) instead of a realistic look. And, for any bird images other than full flight, well, what I said and posted about deer works the same way with grounded or perched birds.
Good! I love it when people are that way! Since that is the case, I would recommend selling the Sigma 50-500mm lens you have and getting one of Canon's lenses that has the 4 stop Image Stabilization, such as the new 100-400 or the super-reasonable 55-250mm. Or you could also consider the 150-600mm offerings from Sigma and Tamron. They are really slow lenses at f6.3, but the modern stabilization really makes up for that.
The way I see it, if you keep using the 50-500mm in dusk and pre-dawn conditions, you'll really need to use a tripod for all of the low-light work you ever do........which is a huge pain in the butt and results in many missed opportunities, due to the time it takes to get the tripod into position and set it up. ISO 3200 and 6400 are just going to give you a grainy mess unless you shoot with a 1Dx or a 1Dx Mark 2. I know I am going to take some heat for that last comment, but it is true - especially if you look at the dark, out-of-focus areas in the frame.
You're from PA.......cool! I was born and raised there. Spent a lot of time canoeing and fishing the Susquehanna between Duncannon and Dauphin, just north of you. I've photographed quite a bit of wildlife in PA.
Ever get up to the Ned Smith Center, about an hour upstream from you? Great place. Studying Ned's paintings and drawings has actually made me a better wildlife photographer!
