I view their afternoon arrival with mixed emotions. On the one hand, I enjoy watching these noisy and colorful, medium-sized parrots. On the other, I know my feeders will soon be empty.
Originally from central South America, the birds were brought to Florida for the pet trade. The first ones were noted living outside in St. Petersburg in 1969. They have since established breeding colonies and are now found across the south-central part of the state. Though the 1992 Wild Bird Act prohibits importation of this tropical species (along with many others) its reproductive success means that it will remain one of Florida’s 195 non-native bird species for many years to come.
I had volunteered for an oyster reef restoration project back in Texas so I was curious to learn about Florida’s methods. The underlying problems are similar, oyster populations have taken a hit from over harvesting as well as pollution and other human-caused disturbances.
The main difference in this area is the amount of boat traffic in the waterways, from not only recreational vessels but also cargo ships and cruise lines. The oyster shell bags we used back in Texas wouldn’t stand a chance against the larger wake, which is where the oyster balls come into play.
The balls, made with marine-friendly concrete, are placed side by side in the intertidal zone and help dissipate wave energy. Oyster shell bags are tucked in behind the balls to add additional habitat (for oysters and other small sea creatures).
We carefully assembled 28 oyster ball forms and once they are cured they will be utilized in a restoration project at nearby Lassing Park. It was a wonderful way to spend a beautiful morning!
