My favorite thing about Merritt Island right now is the Green Heron's nesting in the mangroves. There are also Boat-tailed Grackle's with chicks in the nest, and a pair of Eastern Kingbird's building a nest last time I was there.
At this point you can see all ages of Green Heron's there. Some are still sitting on the nest, others have little fuzzy heads poking out, while various sizes of chicks perch on branches.
