Z6II Auto Focus Test Birds in Flight Part 2 - Long Overdue

This time I'm showing how I captured small birds in flight with the Nikon Z6II. Barn Swallows are amazingly agile. Can the Z6II's autofocus lock on to fast-moving birds? How can you photograph birds without bird detect Ai? I only had 30 minutes at sunset to conduct this test and get the photos. Let me know what you think.
