I have bought the Nikon D7200 with the bigger kit zoom lense, the Nikon AF-S DX Nikkor 18-140 mm F/3.5-5.6G ED VR. Time to give some credit, because it is a perfect companion to the D7200 in the hand of a beginner.
For birds, you have to be very lucky that one decides to pop up right in front of you, or you cheat and go to the zoo. All of the following pictures are from the Cologne zoo, though only the stork is actually hold in an aviary.
