My main camera has gone back east for repairs, so I am using my old backup body.
The ring-necked duck (Aythya collaris) is named for a faint, chestnut-colored ring around the base of the black neck on breeding males, which is often difficult to see in the field. They are commonly known as "Ringbills" due to the distinct white band on their blue-gray bills, a more prominent feature than the neck ring.

I went from having 90% head sharp BIF with my Sony A9 III to around 20% on my OM1-MK2. I love this combo for everything else, but BIF is becoming a problem.as a fellow OM1II and 150-400 user I will be following this thread.
I've been using the 150-400 for nearly 3 years now and I have never achieved even close to a 'great' BIF keeper rate with it.
I usually get something meeting my requirements from most BIF burst sequences though so...good enough.
I shoot 25 fps SH2 so as not to not fill my cards in an instant. It's been said that 'we' should use 50 fps for BIF. I have no argument for/against 50 fps as I've not 'tested' 50 fps for myself.
maybe more salt on the wound...
if you can and haven't already...try the 4/300 for BIF.
when I first received the OM-1 I was using the 4/300 for birds/BIF (with an EM1X).
*I used an A9 and FE200-600 in between the EM1X and the OM-1.
with the arrival of the OM-1 I immediately and very easily achieved a very shockingly high (coming from the EM1X) BIF keeper rate which is what gave me the confidence to buy a 150-400. * I upgraded to the OM-1II when it was released. I have never consistently had a BIF rate with the 150-400 that I achieved with the 4/300 with either the OM1 or II.My keeper rate with the 150-400 on the OM-1 MKII is as high or higher than I get with my R5 MkII and RF 100-500.BIF keeper rate?
Yes. C-AF all points, shutter preferred, auto ISO. Find the bird zoomed out and then zoom in and fire a burst.

Why use C+AF+TR instead of C-AF for BIF's:
