They had reptiles and mammals; like alligators, snakes, red foxes, cougars, and bobcats.
They also had a variety of birds, including several species of owls and hawks. They had just opened a new exhibit, a walk-in aviary, when we went. This exhibit featured many shorebirds like ospreys, herons, and my new obsession, the spoonbill. This was very much my favorite part of the park.
The start of the Homosassa river was located on the grounds of the park, a lovely spring which turned the waters all shades of blue and green and kept the water temperatures at 72 degrees (22 degrees Celsius) year round.
Of course, the park's most notable residents were found in the spring... the manatees. These manatees were non-releasable, and so could not swim out of their paddock, but plenty of their wild relatives can be seen in the lower river and near-by Crystal River, especially during the winter.
There were almost hourly talks being given at various spots in the park, so there was always something to check out. For the most part, the talks were interesting and informative, and tended to coincide with feeding time for that particular animal. My one regret was the very last talk we went to, where the presenter didn't show proper respect for the baby alligator he was handling. That was very distressing to watch, but may be a bug for that particular presenter and not the others as a whole.
So, if you're looking for a place to go hiking and possibly get a glimpse of animals in the wild, Homosassa may not be the place for you. But if you're in the mood for a zoo-like atmosphere and a chance to see some of the native animals up close and personal, this is a good place to go.
