Nikon Z6: Good for Bird Photography? Actually, maybe. 

Is the Nikon Z6 good for bird photography? I'll give you my opinion along with some shots I've taken, mostly with the Nikon Nikkor 500mm f/5.6 PF lens.
The Nikon Z6 is Nikon's first Z-mount mirrorless camera (along with the Z7). Unlike later Nikon models like the Nikon Z8 and Z9, the Z6 has fairly basic autofocus. It does not have subject recognition models either and its tracking leaves much to be desired. But does that mean it cannot be used in bird photography? Not exactly. In some cases, it can produce quite nice bird shots.
I'll talk about my own experiences using the Nikon Z6 with the Nikon 500mm f/5.6 PF for birds. It's not my main camera, but I still like it.
