Anolis punctatus Mating and Feeding

Now for another story from the rainforests of eastern Ecuador. While I was passing through camp on my way to lunch at the Tiputini Biodiversity Station, I stumbled across this pair of Anolis punctatus mating only about five and a half feet above the ground on a small tree. I don’t know when they began, but they disbanded about five minutes after I found them. I probably had something to do with this as the male displayed immediately after separating from the female which you can see below.

Interestingly, the male seems to have a piece of debris stuck in his eye, which he eventually flicks out of his eye at the 40 second mark after mating. Another interesting note is that I spotted the same female (identified by dorsal spot patterning) in the same tree one day earlier where it was perched much higher on a thin branch covered with leaves.

Before I could contemplate what misstep I took in my life that brought me to sit and record the act of two lizards copulating on video, I was preoccupied with watching what this pair would do next. The male split after two hours when he was disturbed by a passing scientist. Prior to disappearing into the canopy he displayed a few times and ate an unidentified insect.

A photoshoot took place after the act. The piece of debris is still visible on the male’s face.

The female stuck around longer and quite low to the ground the entire time. After a few hours she started foraging by perching on Heliconia stems, running into a small patch of leaf litter to retrieve an insect and then returning to another stalk to eat her meal and then stake out the next. I can’t make out what arthropods she was eating, but notice how she gives a few slight head motions throughout (notably at 0:42 and 1:09). This may have been a motion to aid in swallowing food, but I’ve also seen the same female and one other perform this movement outside of the foraging contexts  which leads me to believe it’s a headbob.

Thanks for watching!

Amazonian Anole Displays

The last time I was on Anole Annals, I posted about the peculiar display of Anolis ortonii from the Tiputini Biodiversity Station in eastern Ecuador. Nearly two years later, I was lucky enough to return to the area for another month and bring back some more videos of Amazonian anoles. Unfortunately I never saw Anolis trachyderma or A.chrysolepis show off their dewlaps, but here are three other species.

First up is Anolis fuscoauratus. I didn’t encounter many individuals of this species compared to my first trip, perhaps the differences in seasonality are to blame. I luckily shot this footage only a few days before leaving.

Next is Anolis punctatus, which was surprisingly abundant. I’ll be posting more videos of A. punctatus later as I was lucky enough to observe many other behaviors, but here is the display of at least three different individuals. All of these lizards were found high up in the canopy except for the second to last clip.

Finally, while not as visibly abundant as its cousin, I was fortunate to come across Anolis transversalis. I was photographing some Plica plica on a large ficus, when this lizard descended and scampered across the buttress roots. Eventually it jumped onto an adjacent thin tree and displayed a few times before climbing higher into the canopy.

But this story ends on a sad note. Four days later I was around the same tree when an anole ran down the trunk with an insect in its mouth.

I assume it was the same individual from the other day given the same location, but I can’t be sure. This time he was displaying more vigorously before his arrogance got the best of him. While I was adjusting my camera to get closer a bird swooped in and when I looked up there was no lizard. I never saw A. transversalis on that tree again.

Anolis ortonii Displaying

I had the opportunity to study abroad in Ecuador last year, an amazing experience which culminated in a one-month stay in the rainforest at the Tiputini Biodiversity Station located in Yasuni Biosphere Reserve.  The most common species of anole there was Anolis ortonii, if you knew where to look. Despite several written accounts of A. ortonii being found close to the ground, I observed them in high abundance about 150 feet in the air at the top of a ceiba tree made accessible by a canopy tower.

My experience with Anolis displays in the wild is next to nothing, but  from what little I’ve seen, this swaying seemed unusual to me. Perhaps the more experienced anolologists here can comment on this. Regardless, enjoy the video of a lesser-known mainland anole!
