On the Look Out

An adult male Osprey keeps watch from a height of about 45 feet. There are two chicks in the nest to his left.
I photographed his mate on the same spot on May 11. You can see the image below.

The top image was taken using a camera with a DX sensor and for the bottom image an FX sensor.
For both images the same lens was used zoomed out to 400mm. Both images were also taken at f/5.6 with the same metering and focus settings.
