Where to Bird:

After paying your entry fee at the visitor's center, spend some time scanning the pond in from the deck. This is a great spot to find many species of wading birds and waterfowl. Just past the restrooms is a small feeding station. The hummingbird feeder here is likely to attract Buff-bellied Hummingbirds. Continue along this trail which will lead you to the ponds. All of theses trails can be extremely productive but be sure to take the trails that lead you around Ibis Pond, Dowitcher Pond, and Alligator Lake.

From here, you can enter the Tropical Zone either via a trail from Ibis Pond or from the main parking lot. The Tropical Zone offers a completely different habitat and thus a whole host of different birds. There is a feeding station is this area as well which is definitely work checking. When Rose-throated Becards are present, this is where they are likely to be found.
