Testing the α9II autofocus on Barn Swallows
One of the reasons I switched from Canon, which I used for many years, to SONY is the superb autofocus, but so far I had only tried it on Crested Serpent Eagle and Common Tern, so I tested it on the fast-moving Barn Swallow too. My conclusion: combined with the 200-600mm zoom lens, it is an easy shot. ^^
At this time of year, large flocks of adult and juvenile Barn Swallows heading south on their autumn migration appear over the farmland. Tahiti Swallow, Red-bellied Swallow (アカハラツバメ) and Eastern Red-rumped Swallow sometimes mingle with them.

Barn Swallow juvenile. Young as it looks, it already has the strength for a great long-distance flight.
Another Barn Swallow born this year.
This flock too soon flew off in a southerly direction.
