Green Anoles on Tall Grass in Florida Swamps

031117AnolisVerde1MPLNA(120)

The Florida green anole, Anolis carolinensis, is a trunk-crown anole, usually seen on trees, often high up. So, what’s it doing on grasses low down? Alberto Estrada, an expert on Cuban lizards, reports the following:

It caught my attention to observe several specimens of A. carolinensis (smaller than the one in the photo above) posted on the spikes of the tall grass spikes on the lake shore at Miramar Pineland Park near Pembroke Pines, Broward, FL (25.97 ° N, -80.25W °). In my experience in Cuba with his close relatives A. porcatus and A. allisoni, I do not remember having seen them in such situations. They reminded me of the typical grass anoles such as A. pulchellus from Puerto Rico. As much as I searched, I did not find adults. In Tree Tops Park (26.07ºN, -80.28°W), if I have seen adults on the planks of the platform in the swamp and I have seen juveniles or subadults like the one the photo below in the reeds and on grasses that stand out from the water. I lived and worked for many years in the Ciénaga de Zapata, I had many experiences in marshy environments in the keys that surround Cuba, and I do not remember a single case of seeing the green anoles of Cuba in the same situation. Interesting experience!

In turn, this reminds me of observations I made of Anolis allisoni on Roatan, as evident in the photo below:

New Research on the Pointy-Nosed Anole from Little Cayman (Anolis maynardi

flicker cover

It’s been too long since we’ve discussed that pointy-snouted marvel, the Little Cayman anole. Fortunately, Flicker, the bimonthly magazine of the Terrestrial Resources Unit of the Department of the Environment of the Cayman Islands, has ended the drought, featuring a new research project on one of our favorite species in its most recent issue.

For those of you who can’t get enough of Anolis maynardi, check out some previous AA  posts [1, 2, 3]. For more, just type “maynardi” into the search bar to the right.

 

Fishing Anole Part II: The Lizard Actually Catches a Guppy!

We saw the brown anole jumping into the water in part I, now we see the gory, but delicious, aftermath!

Egret Eats Green Anole

We’ve seen this before. Anoles are, alas, no match for these large and wily marauders. John Karges provides the story: “The egret was flying down the riparian woodland corridor over a side channel, and abruptly landed in the mid-story thicket overhanging the stream and immediately began a stalk. It lunge-grabbed the anole, and very quickly devoured the adult anole in a matter of seconds.”

And here’s where it went down: 2 Oct 2016 San Antonio Mission NHP, San Antonio, Bexar County, Texas.

And the inevitable outcome.

Anolis scriptus on Turks and Caicos, and the Threat of Rats

Concerns Raised over Introduction of Festive Anole to Bermuda

From the September 28, 2017 edition of The Royal Gazette, the daily newspaper of Bermuda.

Fears over lizard arrival

  • Thriving: the brown anole, a new lizard species believed to have arrived from Florida (Photograph supplied)

Bermuda’s latest lizard arrival, the brown anole, appears to be thriving but is prompting concern over the island’s endangered natives.

The lizards, first seen in 2014 and recently spotted on the grounds of Aberfeldy Nursery in Paget, are suspected to have arrived from Florida.

One of that state’s most abundant lizards, the anole arrived there from the Caribbean, where it is native to the Bahamas and Cuba.

Popular as pets but aggressive breeders in the wild, the lizard, distinguished by ridges on its back, has proliferated in the southern United States.

According to the Department of Environment and Natural Resources, Bermuda has two distinct populations of brown anoles.

Genetic analysis shows that the two groups came from “separate founding events”, meaning the second did not arise from the first.

Noting the lizard’s capacity to spread rapidly, Jonathan Starling, executive director of the environmental group Greenrock, voiced concern that the anole would ultimately crowd out Bermuda’s imperilled skinks.

“Unlike the three other Anolis species known to be in Bermuda, the common blue Jamaican, the Warwick or Antiguan and the Barbados, this one is primarily a terrestrial species, the rest being arboreal or tree dwelling,” Mr Starling said.

“The endemic Bermuda skink, already at critically low populations, is also a primarily terrestrial species, so this new lizard poses a much bigger threat to it than the others did.

“I am not aware of the current range of this new lizard but I believe it is still confined within Pembroke and Paget parishes, so at the moment it is not coming into conflict with the remaining known skink populations. However it is likely their range will expand and come into contact with known skink populations within a decade, if not sooner.”

The unwelcome development is the latest of many threats to the endemic skink, which are easily trapped and killed by discarded bottles and cans.

Skinks are also at jeopardy from storms, as well as predation from other invasive species such as cats and rats.

“We’d hope that new initiatives, such as mandatory recycling or a bottle bill, would at least reduce that particular threat to skinks, which would likely benefit them in handling the novel threat posed by this invasive lizard,” Mr Starling said.

Dying Anoles with Eye Problems in Louisiana

AA reader Jonathan McFarland sent in these disturbing photos with the following remarks:

“I hope you can shed some light on what’s happening to the wild anoles in my Louisiana suburban yard. This week I have found two adolescents with both eyes bleeding or infected. The attached pictures show only one side of the specimens but in each case both eyes appeared as shown. Any info you could provide would be much appreciated.”

Thoughts, anyone?

Knight Anoles Introduced to Another Island: Abaco, Bahamas

Photo by Joel Sartore

The knight anole is really getting around these days: Turks & Caicos, Grand Bahama, Grand Cayman and many other islands. Now they’ve  made it to Abaco, Bahamas, where one individual was captured and possibly two others seen (see article in IRCF Reptiles and Amphibians)Abaco Scientist has an insightful discussion of introduced reptiles and amphibians on Abaco.

Female Green Anole with Sand on Her Head–Been Egg-Laying?

Photo-chronicler of Floridian natural history Karen Cusick has done it again. We’ve been captivated by her backyard photos before, but here’s photo of a female green anole with sand on its snout. Been digging holes to bury her eggs, maybe? And while Karen observed the little lady lizard, it suddenly darted into the bushed and emerged with a meal!
