100% skill of course.........
Shoot held at Otterbourne Hides & Studio - Hampshire, England, UK. Images shot with Nikon Z9+400/2.8E-FL+TC14 and a Nikon Z7+70-200/2.8+1.4TC.
Obviously we baited the pond (technically a large bowl) with tiny local river fish, set a perch/branch for the bird to use; prefocused on the centre of the bowl and waited.
This image was shot at 560 mm 1/5000th sec at f/7.1 Exposure Bias -1 EV - ISO 3200 - 120 fps 11mp
Ideally I would have shot at 1/10,000th or faster and with a slightly more closed down aperture f/8-f/11 but the light was far from good. So- it was all I could do to shoot deliberately dark and recover 1+ stops in post.
The flickr album of some of the output from the shoot can be seen here
Album -- you will note that the use of 120fps was the final attempt of the day - I had tried just about every other option available to me on the Z9 and simply could not get "the shot" - sure shots of the birds coming out of the water with fish in their bills, on the branch, on the branch eating the fish -- but not the shot of the bill just pressing on the surface of the water. My simple maths prove to me that the bird moved about 0.6mm while the exposure was taken
