Is the nikon z 28 400mm f 4 8 vr long enough for birds?

Not quite, if birds are your main subject. On full frame it stops at 400mm, and the wildlife and sport guide puts birds at 600mm full-frame equivalent and beyond. It will work for larger birds or ones that let you get close, but distant songbirds will look small.

On an APS-C body it's a different story. The Nikon Z 28-400mm f/4-8 VR frames like 42-600mm there, which reaches the bird threshold. The Z50, Z30, Z50 II and Z fc all take it, and that's the setup I'd pick for birds on a budget. If you want more reach on full frame, look at a 200-600mm or 150-600mm zoom instead, and consider buying used to save on long lenses.
