When a birdnut misses a head-on shot of an incoming BIF (because he was not attentive enough), the capture can still be presented because of the useful details of the seldomly seen rear section. This could be of helpful reference for others to ID the bird in the field.
Common Greenshank (Tringa nebularia)
Shooting Info - Consuelo, Macabebe, Pampanga, Philippines, March 5, 2017, EOS 7D MII + EF 400 DO IS II + 1.4x TC III, 560 mm, f/7.1, 1/2000 sec, ISO 320, manual exposure in available light, hand held, 44.70 m distance, heavy crop resized to 1500 x 1000.
Interestingly, I found out during processing in CS6 that the camera records the focus distance, but PS doesn't incorporate it in the EXIF data of the output file. This was taken at about 44.70 m distance (as recorded by the camera in the RAW file and manually viewed in CS6's file info menu). At that distance, the bird occupied just a small portion of the frame (see below), given the modest 560 mm reach. However, the pixel density of the 7D MII allowed a 3.8 MP crop (as presented, resized to 1500 x 1000) that improves the composition and can be printable to a decent quality 12" x 18" photo.
