Sorry to open with a nitpick, but there is more than one APS sensor size. For instance, a few Canon models have an APS-H sensor, which has a 1.3 crop factor. Your D80 has an APS-C size sensor, with a 1.5 crop factor. Strangely enough, Canon's Rebel series are also designated APS-C even though their crop factor is 1.6. None of these match the exact size for the original APS specifcations.

I can't really comment on Sigma, Tamron or Tokina tele-zoom lenses, other than to say they will generally be less expensive and produce lower quality results.
Nikon does't make a 100-300mm lens. If you want a zoom lens that covers 300mm, your choices are:
AF-S NIKKOR 28-300mm f/3.5-5.6G ED VR
AF-S DX NIKKOR 55-300mm f/4.5-5.6G ED VR
AF-S VR Zoom-NIKKOR 70-300mm f/4.5-5.6G IF-ED
AF VR Zoom-NIKKOR 80-400mm f/4.5-5.6D ED
AF-S NIKKOR 200-400mm f/4G ED VR II
None of these is very fast, so will be of limited use indoors or in a forest.
I don't see much point in you buying the 28-300 mm. It is intended as a walking around lens for a fullframe body. It isn't wide enough for you to use as a walking around lens on a DX body, and it overlaps most of the range of your other lens. Also, it has rather cheap construction.
The 55-300 mm DX lens is an inexpensive and lightweight ($430, 1.1 lbs) solution, but will not give full frame coverage. This is only a concern if you think you will upgrade to a full-frame body. The lens has good optics, but is slow to focus, so is not good for moving subjects.
The 70-300 mm is only a bit heavier and a bit more expensive (1.6 lbs, $540), but will cover a full frame. It is quite a good mid-value lens except for a tendency to produce noticeable lateral chromatic aberration at long focal lengths. This can be corrected in post processing, and is automaticaly corrected by some Nikon bodies (but perhaps not the D80). It is a bit sharper and much faster-focussing than the 55-300 mm DX.
The 80-400 is older, heavier, slower and more expensive than the 70-300, but it does get to 400mm.
At $7k, the 200-400 mm is probably out of your price range. It is also huge (14.5" long, 7 pounds).
You could also consider a prime telephoto lens. The AF-S NIKKOR 300mm f/4D IF-ED is probably the only one with low enough price and weight. (3.2lbs, $1.4k)

When considering wildlife lenses, you need to think about how much you are willing to pay, how much size and weight you want to carry, what sort of image quality you want, how fast a lens you need, and how rugged a lens you need.
Relatively cheap and lightweight lenses will have lower image quality and lower build quality. They might not withstand the rigours of extended back-country hiking.
If your subject is not under canopy, then you can probably get away with slower than f/4. If your subjects include birds, small mammals or dangerous animals, you might want an EFL of 600+ mm (a 300mm lens on your DX body has only 450mm EFL).

Nikon's 70-200 mm f/2.8 VR II lens is one of the very best DSLR lenses available. Incredibly sharp even almost wide open, almost no distortion or aberrations. It is sharper in the centre than the Canon equivalent, but sharpness drops off faster towards the edges. On a DX body, this will not be a problem. When it first came out, there was controvery about its greater than usual loss of focal length at minimum focussing distance. For wildlife shots, this is also not a problem. The lens is not light or cheap (3.4 lbs, $2.4K).

I've been really tempted by it myself a few times recently but just haven't pulled the trigger.
I'm a big fan of walkabout or travel lenses. I take more shots with my 18-200mm than any other lens. However this sort of lens is a compromise. It comes with noticeable distortion, less sharpness, and lower build quality. One signficant problem with cheaper super-zoom lenses can be the possibility of sucking dust into the camera body. You get this sort of lens for portabilty and versatility, but not for image quality.

Nikon do a 28-300 f3.5-5.6, but I have no idea what it's like.
See my comments above re the 28-300.
There is yet another approach: use a teleconverter with a fast mid-range zoom. There are 1.4x, 1.7x and 2.0x teleconverters. They increase the focal length by the stated factor, while slowing the lens by 1, 1.5 and 2 stops, respectively. They are relatively light and inexpensive. Teleconverters are
not compatible with all lenses. They generally do not work with inexpnsive lenses or DC lenses.
I bought the 70-200 mm f/2.8 VR II lens for indoor stage events and sports. I can also use it for forest animals. When shooting wildlife in the open, I add a 1.7x teleconverter. This effectively gives me a fast-focussing 119-340 mm f/4.4 VR II lens. On my DX body, that's a maximum EFL of 510 mm.
Does it work? You be the judge:
Except for cropping, that's the JPEG that came out of the camera. There was no other post-processing.
This combination isn't quite long enough for serious birding, and you won't often get this close to a wild eagle. The 2.0x teleconverter combined with this lens gives 140-400 mm f/4.8, with a max EFL on DX of 600 mm.
