Where you go to look for them, and where they happen like to go that particular time dictates whether you see them or not!
The mangrove wilderness boat tour took us into the dense swamp and mangrove part of the Everglades where water is brackish, and mangroves are dense At the boat lunch area, a brown pelican lazily rested on top of post, nearby a grey heron patiently standing in the shallow water waiting fishes to swim by. As the captain sped up in the water way in search of dolphins, we saw many birds along the way.
As we made a few turns, we got into a Egrets paradise, hundreds of Egrets standing along the edge of mangrove As we were approaching mangrove formed tunnels to look for alligators, and the air stunk big time. We did not see any alligators there, but the egrets flying in front of our boat was really exhilarating!
