Female Mallards here usually have 8 to 12 ducklings. After their first month on the ponds they will be lucky if even one or two of them survive. The female tends to them on her own and has no real defence against predators. The best she can do is to try and distract any predator. Sadly as they grow older they scatter further away from their mother, making them even more vulnerable.
What predators? Mink, river otters, hawks, and owls mostly.

When myself and another person noticed the dark coloration around this eagle's neck, we thought it was from getting its head in the mud when foraging for midshipman fish. However, no other eagles looked like this and it looked the same the next day.
I thought maybe it had been shot through the upper part of its beak, but that would not result in the dark feathers.
My guess is that its beak came in contact with a high-voltage line and the electrical charge blew off part of its beak and burned the feathers.
The eagle appeared to be very aggressive and adept at catching the midshipman fish.
Long distance, heat shimmer, and heavy crops prevented me from showing better detail. ...Show more →
Just returned from a trip to Iceland & Norway and a little worried about how many keepers I have got from flying birds. Not many have the head sharp in focus. Is there something I am doing wrong? My exposure is 1/3200–1/4000 so that shouldn't be a problem. Using C-AF, Bird detection, AF Area - Large or All, SH2. Can't use back button focus due to my disability. 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.
Yea I use 50 fps a second, someone on another forum said to reduce the AF area to the smallest, literally the opposite to what I had to do on my Sony before..will give it a go.

"someone on another forum said to reduce the AF area to the smallest"
that is interesting advice.

Yep and I prefer to use the Olympus due to the excellent IS when locked on.
700mm at f/10 (rf 100-500 + 1.4TC) vs Gandalf the Great White Wizard at 800mm (FFE) at f/4.5
