I have been shooting the Egrets later in the day this year. That has been when they are most active. It also has provided some nice reflection photographs.
Each of these images was taken on a different day (at least I’m pretty sure they were) but the light was consistent in the early evening.
The water has been clear also which allows for the better reflections.
As we get into the warmer weather the clarity of the water will change. More Duck Weed and other greenery will collect and images will look less reflective.
