By the close of 2019, I was prepared for a transform of surroundings. Working as a organic record photographer, I’d spent the former two yrs tracking snow leopards in the Himalayas. Then, a person snowy afternoon, I gained a quick phone from Dr. Rohit Naniwadekar, a chook biologist with the Mother nature Conservation Basis. He questioned me to get to a compact volcanic island in the northern Andaman Sea as speedily as I maybe could.
Within a 7 days, I had swapped the seemingly unlimited landlocked mountains for a very small speck of land at the edge of the world.
Narcondam Island, a designated wildlife sanctuary where Dr. Naniwadekar planned to carry out his analysis, presents new that means to the word “remote.” Situated about 80 miles to the east of the primary spine of the Andaman Islands and totaling only about 2.6 sq. miles (2 times the dimension of Central Park), Narcondam is a dense inexperienced volcanic mountain peeking out of the deep blue water. To date, exceedingly couple of researchers and natural history photographers have set foot on its uninhabited beach locations.
Getting to Narcondam, which is part of the Indian union territory of Andaman and Nicobar Islands, was not uncomplicated. Right after gaining the right govt permits, we caught a flight from mainland India to the Andaman Islands — simple adequate. But that was adopted by a prolonged night in tough seas to attain Narcondam. Additionally, the island does not have a docking or smooth landing solution, so we experienced to bounce into little rubber boats and struggle the waves ahead of disembarking. We ended up drenched from head to toe.
Eventually, the five of us — a few experts, a wildlife biologist turned artist and I — discovered ourselves forged away with not a lot extra than our tools, some dry rations and a healthy dose of excitement.
The team’s primary goal was to examine and document the Narcondam hornbill (Rhyticeros narcondami), which is endangered and endemic to the island. As luck would have it, we saw our 1st pair flying previously mentioned the beach front as before long as we hit land.
Obtaining observed the Terrific Hornbill of mainland India myself, I recognized that these hornbills were smaller sized than I had envisioned. But they have been nonetheless stunning. The male is a little more substantial in measurement, with a rufous-colored head and black entire body, although the feminine is solely black. The bird’s closest extant relative is the Blyth’s hornbill, uncovered in Papua New Guinea.
Within a few several hours of our arrival, we recognized that Narcondam hornbills were being in higher abundance, even if limited to the island’s little spot. Pinpointing how several of them exist and what components inspire their abundance have been two of the vital inquiries that Dr. Naniwadekar’s group aimed to recognize throughout the two-month stop by.
Exploring Narcondam was a challenge. Its steep terrain is composed of ridges and valleys shaped out of unfastened, crumbly rock, which is held together by seemingly impenetrable shrubbery and woody climbing plants regarded as lianas.
Still, each individual working day we established out in a different path from our base, permitting the island’s attractiveness to unfold before us. Some patches were being dry and reminiscent of a deciduous jungle, while other individuals were being mist-laden and identified as to intellect dense cloud forests.
We created our way across tangled underbrush on our hands and knees, and gazed up at large buttress trees, some 130 ft tall, filtering sunlight via layers of the cover down to a carpet of ferns down below.
In time, the group started investigating the hornbill’s shocking abundance. They walked line transects at unique elevations to estimate the bird’s inhabitants densities. Vegetation plots have been laid out in an attempt to recognize floral diversity. Camera traps ended up put in around fruiting trees to research the impacts of rodents on native plants.
The do the job was time-consuming, bodily demanding and monotonous, but the thrill of getting and identifying different species of crops and animals though out in the subject was enough to buoy the spirits of the full social gathering.
In the course of the day, shouts of Latin names of different vegetation and birds echoed as a result of the forest. Arrive night, we’d kick again with contemporary coconut h2o in the ease and comfort of a hammock. At night, we’d stare out into the ocean, contemplating the foundation of the island that lies beneath the water’s area, dreaming of all the everyday living we couldn’t see.
Some days, I’d enterprise out on my possess to search for nests, sitting in trees for several hours on end with a zoom lens, hoping to capture shut-up visuals of the hornbill. I became fondly common with the ruckus they’d produce while playfully chasing every other or feeding on a ficus tree.
Narcondam hornbills have large beaks that they use to pluck thick fruit, which they carry on to toss delicately into the air before swallowing it or supplying it to a mate.
It was courtship time, and we have been dealt with to an explosion of habits that was tough to unravel. For months, we noticed frequent vocalization, courtship feeding and pair-bonding involving likely mates as they identified as out to just about every other. The pairs would hang close to nests, cleaning them in switch, traveling together, feeding alongside one another, preening 1 a further ever so carefully.
Even though I was hectic photographing these birds, the crew started out to piece with each other the puzzle of the hornbills’ populace. They estimated almost 1,000 birds, corresponding to a density of about 390 birds for each square mile — much exceeding all the recorded densities for any other hornbill species on the earth.
Moreover, the density of the island’s fruit trees — in particular that of the figs consumed by Narcondam hornbills — was amongst two and 10 times as high as in comparable forests.
“Figs have a exclusive attribute of staggered fruiting,” spelled out Dr. Navendu Web page, a scientist at the Wildlife Institute of India and the team’s botanist. “So at any offered time there are a handful of trees in fruit on the island, which makes sure a continual source of food for the hornbills yr-round.”
Besides figs, other native crops also manifest in profusion. And due to the fact hornbills are the major frugivore on the island, Dr. Webpage theorizes that the birds correctly tweak the distribution of trees to favor the types they feed on. In other words: By spreading the seeds by way of their droppings, the hornbills are steadily reworking the island into their individual Backyard garden of Eden.
Still, the birds confront difficulties. In modern a long time, the Andaman and Nicobar Islands have been a critical asset to India in the country’s effort and hard work to counter China’s enlargement into the Indian Ocean. As such, the archipelago faces chance from likely infrastructural advancement.
Climate alter is also a possible menace, significantly given that it’s known to disrupt the fruiting designs of vegetation. “In this kind of a tightly connected ecosystem,” Dr. Naniwadekar explained, “just 1 or two undesirable fruiting several years may significantly influence the hornbill populace.”
Rats, not indigenous to the island, have also invaded Narcondam. Initial digital camera lure experiments suggest that they are feeding thoroughly on sure seeds and might sooner or later alter the island’s floral composition.
At the conclude of our just about two-month sojourn, as some of us departed on rubber boats towards our extraction ship, I saw a pair of hornbills traveling into the open sky, glowing in the golden light of dawn. It struck me that this could properly be the last time I established eyes on these birds — true “evolutionary miracles,” as Dr. Naniwadekar had as soon as described them.
“They should really be specified the identical respect and security that we offer to the gentleman-produced miracles of our world,” he included.
