For many years I've used a D7200/Sigma 150-60mm lens for bird pix. For perched birds, it worked very well; BIF, not so much. Recently I found a 'like new' D500 at MPB for a decent price.
I've been studying the manual, and also found a Nikon manual "D500 Professional Setting Guide, sports AF edition", which I thought might be helpful in choosing the correct settings for BIF. However I see this on page 6:

OK. But why does the 3D tracking selection spell out "3D' in focus points? And what subjects are considered?
The next page reads:

Was a column on the left omitted? This doesn't make any sense.
Anyway, I'm guessing that for BIF, you want 3D tracking.
And later on, page 18, the discussion about Focus tracking with lock-on, for BIF you want blocked AF response delayed, and the Subject Motion steady for large birds (eagles) and erratic for birds like swallows?
Thanks in advance for any help.
