Great Egrets in flight at Lake Hefner
This is a great evening location for getting Great Egrets in flight. With the sun to your back, you are able to get them flying back to the dam with fish they just caught. You might also be able to get them in action as the dive in for fish. I have never seen Great Egrets feed this way. They hover over the water until they see a fish and dive down for it.
You can park on the dam at Lake Hefner. I feel that the area with the blue circle might be one of the most active spots. I believe that they won't be feeding this way if the wind isn't blowing. I will need to spend more time here to be certain.
