I could have also called this ‘being in position’. By that I mean having setup in the right spot and have the camera/lens ready as you want them. Ready for the big ‘event’…should it come along.
There are several spots in this rookery where photographers setup. The idea is a clear field of view, no branches, hanging moss, etc., and several active nests/birds.
Some days you can fill a memory card with the opportunities. Others, a few shots and you need to move on.
Even on a great day it’s important to change your angle over time. If you stay planted in the same spot you can get 500 good Egrets in flight images, of 10 different birds…and they will all look the same!
