A Few Exotics in Miami

Tuesday May 26th

The semi-tropical climate in South Florida lends itself well as a new home for exotic plants and animals. A great many are considered to be pests and the most successful can be quite harmful to our local ecology. The rise of the Burmese Python population in the Everglades is a prime example. Ornamental plants and trees have also overtaken local flora like the expansion of the Melaleuca and Brazilian Pepper. Their is a bounty on the Lionfish, which has rapidly prospered on our Florida reefs, upsetting the ecological balance by becoming an aggressive top predator, prolific breeder with no known predators in the Atlantic Ocean. Iguanas have become established in most of South Florida with some getting  to be over four feet long.
 Not all invasives cause great ecological harm. Just a few minutes ago I spotted the House Gecko that has moved into my apartment. I don't mind its presence at all as he'll consume most any insect pests.  Many of the exotic bird species have not become major issues. The Monk Parakeet though builds huge nests artificial structures and have created damage such as electrical outages. But most of the many parrot species in south Florida aren't as disruptive the ecology as originally feared.

This past week-end Bob Pelkey and spent four days birding the Miami and Florida Keys area for exotics and came up with several.

Red-whiskered Bulbul in Kendall
Red-Whiskered Bulbul -  A native of eastern India,

Purple Swamphens - A common native in Africa, southern Europe, much of Asia including Indonesia, and Australia.

Common Hill Myna - The Common Hill Mynas are a species of starlings and a very popular cage bird coming from the hill regions of southern Asia.

Muscovy Ducks - The Muscovy Ducks we find all over south Florida are actually feral specimens of domesticated Muscovy ducks.

White-winged Parakeet - Once a very common species in Miami, but its numbers have been falling as the Yellow-chevroned Parakeets.have been increasing.  Both species were once known as canary-winged Parakeets. White-winged Parakeets came from the northern Amazon River Basin.

Iguanas - Both Green and both species of Spiny-tailed Iguanas are found in south Florida. Theses populations have there start when iguana pet owners either loose or release the big lizards.
