I bought a Nikon Z7 and Tamron 150-600G2. Very happy with the Tamron lens, but found the Z7 too slow for wild life...replaced it with a Nikon D850. Nikon 24-120 f4, Nikon 20mmf1.8 and Tamron 70-200 f2.8 G2

Also nikon D5500, 16-85 Vr Dx and 70-300 VR DX, and my preferred safari lens:

My prefered equipment for wildlife is a Nikon D500 and my newly acquired (used) Nikon 180-400 f4 with built in TC .
