Today, I found about 20 Bronzed Cowbirds along SW 217 Ave in Miami-Dade county, with another ten or so at Homestead General Airport. Near the intersection between 217 Ave and SW 288 St, I had a single Shiny Cowbird.

Andy,
Smooth-billed Ani definitely merits a post on the rarity report! I think they are pretty much extirpated as breeders in Florida.

Most of the exotic reptiles here in South Florida are from Latin America, where Smooth-billed Ani is abundant. I do not think has anything to do with nest predation from exotic reptiles or even habitat loss, as they deal with almost any kind of scrubby habitat in their usual haunts. I think it might have to do a lot with spraying for insects, which they do throughout suburban Miami-Dade and even in the Everglades.

Several factors have been hypothesized as for the reasons why the Smooth-billed Ani population has declined in FL. It now seems that not only one factor is to blame but perhaps a combination of factors. This combination of both natural and unnatural factors including hurricanes, freezes, floods, droughts, as well as human alteration of the environment such as pesticide usage in agricultural lands. These factors all play a role in the disappearance of SBAN in FL. Unfortunately for the species it may no longer be established in South FL.
Smooth-billed Ani population grew exponentially into the early 1970's with 1,146 individuals tallied on the 1971-72 Christmas Bird Count. Compare that to just ten years later when CBC data shows only 219 SBAN recorded during the 1981-82 CBC. The species numbers continued to decline rapidly with only 63 individuals counted during the 1991-92 CBC. Another ten years later and only 15 birds were counted, fast forward to 2011 and they are all but gone. The last two CBC's have turned out 0 individuals during the count! Presently reports of SBAN seem to be that of stragglers or vagrants such as this new report of a bird near the Miami International Airport.

Is there a website where I can find a listing of the rare birds of Florida? I can find species lists for Florida and areas within FL, but not one that lists the rare birds. Or perhaps I'm just not looking...
Hey Azzy, here is a link to the official state list and review (rare) species are indicated on the list. Hope that helps.
http://fosbirds.org/official-florida-state-bird-list
with that being said, there are certain species that merit mention on this thread mostly because they show up infrequently but are not considered mega rare and are not subsequently reviewed by the FOS rare birds committee. Species such as Hudsonian Godwit, Black-legged Kittiwake, Glaucous Gull, Calliope Hummingbird, La Sagra's Flycatcher, Lapland Longspur and Black-throated Gray Warbler, to name a few, would merit mention but they are not mega rare.
The Birdlife of Florida by Henry Stevenson would also give you an insight into the status and distribution of Florida's birds.
