What is even more intriguing to me is the fact that southern Collier County, in places like the Fakahatchee Strand and parts of the Big Cypress for example, do have some remnant tropical hardwood hammocks albeit not as extensive as Miami-Dade's Matheson Hammock, Sadowski Park, A.D. Barnes, etc., but yet we rarely get wintering birds that are otherwise common in those places. Warblers like Black-throated Blue, Black-throated Green, Worm-eating, etc. Even in migration, these birds are rare here. Nor do we ever get White-crowned Pigeon with a few exceptions or Antillean Nighthawk, etc. etc. And we're only a little over 100 miles away from Miami-Dade. Funny how 100 miles and a slighly different biogeographic make-up can make such a huge difference. I think Toe is on to something with regard to more northern species coming into inland Collier County places like Immokalee where the temperature difference in winter are as much as 15-20 degrees different than in coastal Collier County. However, the biogeography is not significantly different than on the coast for the most part.
