Which Nikon DSLR is good for bird photography

I would not recommend any Nikon DSLR for bird photography on a budget because you will need at least a 400mm (or 300mm f4 with 1.4 TC), lens and those are expensive, large, and heavy. Instead I would recommend a Nikon V1 using the FT-1 adapter with an FX or DX lens. Here is a link to a birder named Malcolm Farrow, that does just that:

I have tried doing some birding with the 70-300G VR on my D7000 and found that I needed much more reach, so I bought a 120-400 Sigma lens. It's still not enough reach for my needs though, so I'm now looking at using my Nikon V1 with FT-1 adapter and a sharper 300mm f4 lens instead.
