Your camera+lens+TC might need an AF Micro-adjustment (AFMA). At say, 12 feet, 560mm at F8 your depth of field is about 3/4 inch. Not much room for error. Also, when using the 100-400+1.4 TC it might help to stop down a bit if you have enough light. It has been said that the 100-400+1.4TC combo is sharper when stopped down a bit. With mine I usually use F9.5 as a minimum. You were shooting at 1/1600 so you had room to trade some speed for aperture. The big whites are different, they are sharp wide open. But they are primes and cost 5 times as much. Just my opinion. The shot below was ISO800, F9.5 with 5DsR, 100-400L MKI, 1.4TC MKII at 560mm. About a 1/3 crop. I used center point, single shot AF. BTW, I got the same results when shooting with my 5D MKII.
Thanks for all that good advice, AaronT.

I never get sharp shots through windows.
I think, this starling (though almost twice the size of a nuthatch) looks much sharper, though shot from the same position, with worse light.
So to me it is not so much about windows and not so much about AFMA but more about my technique or a steady hand. But I'll keep both in mind and try.
Here I loose sharpness also because of ISO 3200 and noise surpression.

Not easy to understand for a non-native speaker, but as I said, "I'll keep both in mind and try". Thank you, again.

But I already did my tests and I see not much difference with window open or closed, shooting at a - non moving - bud.
If interested I can show you examples.
But of course I am also aware that my window glass is not coated as optical glass is and so I try to avoid any kind of reflections and get as close as possible to the window glass.
If I manage to get the "sharp" shot through the window, I'll let you know - fully aware that I might be mistaking...

That photo of the Blue Jay was taken through 2 panes of glass. :)

I am still practicing on small birds. Here is a nuthatch shot through the window from my home office workplace.
Still thinking about why my AF is not spot on, exposure data is:
5D3, 100-400L2 with 1.4xTC3 @560mm, f/8, 1/1600, ISO 1000, croping to 1/3 of original size.
Th reflection in the eye looks really sharp - so it seems to be either a front focus issue or a DOF issue.

Thanks Mike!
At full resulution (RAW, can share if you like) the reflection looks close to sharp, but not really.
I did set the center AF point on the breast of the nuthatch. Normally I go for the eye or at least the head. Can't remember the scene, but maybe I was too exited or in a hurry. When you look at the branches to me it looks like motion blur (@ 1/1600 !!!), either my hands, some wind or the IS. Not sure whether I'm wrong or where it comes from. Still guessing...

Very cute! Can you believe, last night -20C here in central Alberta and the Canada Geese are arriving anyway. That's very close to a record low that was set last year - hope it's not a trend!
And here close to Nürnberg the winter lasted about 3 days
Some cold nights, even down to -12 Celsius.
But only 3 days of snow. Eternal fall.
Moss has taken over all of my lawn.

Here in Calgary, South Alberta, finches showed up a week ago. Cheerful and cute birds. I hope they survive the current cold front (-12C today).

I guess we all have our positives and negatives. We're called sunny Alberta and I love the sun especially when it's April and -20C. It doesn't help much for camera use outdoors though.

The Longtailed Tits in my garden building a nest continue to amuse me. Here is one of them high up in a tree beating the hell out of a feather that he will use for lining the nest. Apparently, they "recycle" feathers from dead birds.
