A Week on Glover’s Reef Atoll

I don’t know what I expected from a sandy spit of coral thirty miles off the coast of Belize, but it wasn’t this! This lush thirteen-and-a-half-acre island is a vibrant, flourishing, diverse patch of nature. What a week!

Looking north at Long Caye, one of five cayes on Glover’s Reef Atoll.

Atoll: A ring-shaped island, including a coral rim that encircles a lagoon. There may be coral islands or cays on the rim. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Atolls are formed by the sinking of a volcanic island around which a coral fringing reef has formed. Over eons, the volcanic island erodes and subsides completely beneath the ocean. Eventually, the reef and the small coral islets on top of it are all that is left of the original island, and a lagoon has taken the place of the former volcano. 

The western half of the caye is an undeveloped palm forest bisected by nature trails. Every time I walk these paths, I see something new that fascinates me.

Hermit crabs are everywhere, constantly crossing the trails hauling their shells on their backs. At my approach, they recoil into their mobile homes with varying degrees of success.

They outgrow the snail shells that they’ve commandeered and have to make do until they find a bigger, more suitable one. Whenever I notice a large, empty whelk snail shell, I pick it up and carry it with me until I see the right-sized crab in a too-small shell. I place the empty shell next to the crab and step away. The grateful animal will inspect the gift and then quickly make a move.

The locals say that hermit crabs are barometers of the weather; when it’s going to rain, they go up (with a perplexing ability to climb!), and when it’s going to be windy, they dig in and disappear.

I also see lizards on every walk. The anoles live in the trees and understory, basking in every bit of sunlight. Adorable tiny brown anoles, the length of my thumbnail, with adorable teensy feet and a tail equal to the length of their bodies, must’ve hatched yesterday!

The island’s iguanas, mostly spiny-tailed iguanas with a rare green-tailed iguana, are out on the south rock walls, even on gray days. Once I spot one, the others materialize from their camouflage in striking numbers!

How many iguanas can you find? They blend in so well. I circled the first one to get you started. (Answer image at the end of this blog)

When the sun is out, and they’ve charged their batteries, they are along the trails and in the bushes and trees, too.One iguana didn’t flinch as I approached. He was like, “I own this trail, go find your own.” I obliged.

Magnificent frigatebirds flock over the caye, resting on the wind, going nowhere. Great-tailed grackles’ constant chatter fills the air.

A couple of brown pelicans rest on the caye and fish these waters, as do a pair of resident osprey.

Each morning, about twenty minutes before the first rays of sun begin to push back the night, the osprey start calling back and forth in a high-pitched volley reminiscent of raucous gulls. We called them the island roosters for the way they celebrate the start of each new day. Ospreys are adept fish eagles, always announcing their fishing successes and perching on their same favorite branch to pick apart their meal. (Such a courtesy to photographers!).

A green heron hunts a conch pile left by migrant fishermen. Ruddy turnstones walk the sargassum piles, feasting on tiny arthropods. A yellow-crowned night-heron has been regularly spotted in the mangroves near here, but has eluded me all week.

As I’m heading to look for songbirds in the brilliant orange scarlet cordia blooms, a white-crowned pigeon streaks past me, followed instantly by a merlin in hot pursuit. Just a flash and they were gone. Later, I would watch a pair of merlins soaring, dipping, diving, veering like fighter jets they are. 

Years ago, a previous landowner purchased a few gibnuts, large, native, ground-dwelling rodents with dots and stripes on their sides, at a local meat market and set them free on the caye. They’ve since established a breeding population here. I set out to try to find one of these nocturnal, exotic guinea pigs. I noticed what I thought might be gibnut tracks and excitedly went to share my discovery with a fellow traveler. His face fell when I described the track pattern as being similar to a rabbit’s. “There’s a rabbit on the island,” he reluctantly responded, not wanting to stifle my enthusiasm. What?!? Yeah, the same story as the gibnut. Three domestic rabbits from a meat market were neutered and set free here. One remains.

Like cats respond to “Here kitty, kitty, kitty” or “pspsspspss”, rabbits respond to a speedy, high-pitched “bunny-bunny-bunny!” And so it was the next day when I saw a black and white rabbit resting under a deck. I called, and out he hopped!

Towards the end of the week, I did find several gibnut tracks, but unfortunately, never the animal itself, despite some nighttime exploring with my headlamp.

On the last day, an early trail walk finally revealed hummingbirds. Green-breasted mango hummingbirds! A male feeding at the scarlet cordia and a female with a dramatic white belly cut by a stark black stripe flitting around the buttonwood. I’ve never seen these birds before. Black and white on a hummingbird is so exotic!

The yellow-crowned night heron eluded me on the caye all week. Serendipitously, when we docked back on the mainland, there in the marina, perched out on a palm branch, sat a yellow-crowned night heron!

A Glimpse into the Life of Caribbean Reef Octopus

With headlamps and flashlights, we slowly step across sharp rocks along the edge of the eastern shoreline. It’s 7:30 pm, and the tide is out on Long Caye on Belize’s Glover’s Reef Atoll. Our guide shines his light on a blurry turquoise blob distorted by the waves on the beige sea floor. “Caribbean reef octopus,” he says. “If you say so,” I think to myself.

We move on. Tidal Splash crabs scatter sideways at our approach. There’s another octopus! This one is in calmer seas, her characteristic shape more easily evident undersea.

She slides in our direction, out of the waves and into the still edge of the ocean where her full brilliance is revealed. Iridescent turquoise-blue and green, spotted with reddish-brown. Slithering, reaching, feeling – hunting! Caribbean reef octopusA few more steps and there’s another! This one is already at the water’s edge. He’s after the Tidal Spray crabs at our feet! He strikes with his long arms and misses. But he knows where they went and slinks around a rock to head them off on the other side. He strikes again in a flash and pulls one into his mantle.

At the end of the video, one crab escapes, and one does not. You can see the crab leg in the crevice on the left before the octopus pulls him down.

We watch him for a minute and then leave him with his meal.

A bright red fiddler crab pokes out of her hiding spot to shoo off a Tidal Spray crab and instantly disappears back into the shadows.

Another octopus! This one is also close to shore. She is hunting using a common octopus technique; she spreads her skirt over the bottom to siphon her prey out of the crevices where they hide. We watch her deftly catch something and begin to eat. It’s a sizable meal for her.

 Caribbean reef octopuses are a medium-sized octopus, growing up to twenty inches in diameter. They are short-lived, like most octopus, with a lifespan of just ten to twelve months. In all, along a hundred yards and forty-five minutes, we saw twelve (TWELVE!!) Caribbean reef octopuses on this walk.

Other Exotic Night Life

Also venturing out after dark in the ocean, giant sea slugs called spotted seahares creep along the sea floor. The way they move and explore their environment with their mouth and tentacles, just like a shell-less snail, identifies them as gastropods. Ruffled parapodia on their backs cover their mantle.

Note the ruffled edge of the parapodia along the middle of her back. Her head is to the left.

They secrete foul-tasting purple ink to cloud the water and deter would-be predators. I’d heard of these animals before, but never expected to see one here!

A gorgeous King Helmet conch (also a gastropod) feasting on a spiny urchin was within reach.

This is a big conch – more than a handful – with a striped, domed shell featuring a flare at one end.

Endlessly fascinating!

Lastly, a young morey eel is tucked into the safety of the coral, part of his striped body visible through a hole. He cautiously peeks his head out from the end of the coral, sees me still there, and retreats into hiding. He’s less than twelve inches long and the diameter of my thumb. A far cry from the six-foot-long green eel I saw snorkeling yesterday!

The sea is full of exotic-looking life at every turn. It never ceases to amaze. I am blessed that so many creatures reveal themselves to me. Even so, this was an exceptional shore walk.

Stay tuned for more Belize wild tales!
