We peek over the jetty, scanning the rocky seashore by binoculars, earlier than ducking right down to talk about in hushed voices our subsequent transfer. We’re on Robben Island in search of African oystercatcher (Haematopus moquini) nests. This island is one in all the few locations the place these charismatic shorebirds, that mate for all times, can breed safely from the beachgoers’ canine who terrorise their chicks.
By “we”, I’m referring to Les Underhill — the writer of my first-year statistics textbook, head of the Biodiversity and Improvement Institute and retired College of Cape City statistics professor — and I, a lately graduated conservation biologist. I’m studying to search out the nests of the bright-red billed and glossy-black plumed birds who I will likely be monitoring for the remainder of the summer season breeding season.

Russia and a revolution
Underhill teaches me a method for locating nests that he perfected as a boy on Rondebosch Frequent, a 40ha conservation space within the Cape City suburb the place he grew up. It’s the exact same know-how with which he wowed Russian scientists on his expedition to the Arctic. That journey was again in 1991, a couple of months earlier than the breakup of the Soviet Union.
So how did a South African stats professor land an all-expenses-paid chicken monitoring expedition to the Russian tundra because the visitor of a rustic that was then, on the tail-end of the apartheid period, an implacable foe of his personal nation?
Sharp-eyed readers will be aware the purple knot (Calidris canutus) sitting on her nest close to Lake Pronchishcheva, Taimyr Peninsula, Siberia. Explorers looked for the nests of this chicken for many years earlier than discovering the primary one in 1909. Throughout his time within the tundra, College of Cape City Statistical Sciences Emeritus Professor, Les Underhill had to search out and monitor the nest of those cryptic creatures each three days.

The reply lies in Underhill’s knack for bringing collectively an enthusiasm for birds — which hatched when he was a boy — with statistical experience developed in the course of the course of a distinguished educational profession. As he explains it, his intention has been to “put stats into biology and produce biology into stats”.
His pioneering work led Underhill to determine two organisations that observe modifications in nature, relying closely on “citizen science” tasks. These collect information over bigger areas and for longer durations than any particular person researcher might handle alone. In the end, they’re serving to to create a digital reminiscence financial institution of plant and animal particulars, spanning Africa and drawing on the labours of generations of researchers and citizen scientists.
The depth and breadth of the database permits researchers to higher look at patterns and observe modifications in a variety of species. It means findings might be formulated extra rapidly, crucial for conservation. And due to Underhill’s efforts, any common Joe with a smartphone and entry to the web can turn out to be a nature fanatic and contribute to conservation as a citizen scientist.

Early genesis
Underhill has by no means regarded birds, biology and the enterprise of number-crunching to be odd bedfellows. All through his profession as a statistician at UCT, he’s given wings to avian pursuits which initially “rubbed off” on him as a lad, due to his father who was an avid birdwatcher.
As a scholar, Underhill was a part of the primary profitable wader analysis group within the southern hemisphere. (Waders are a gaggle of birds that “wade” by sand or mud to search out their meals.)
“We caught and tagged tens of 1000’s of waders, primarily at Langebaan Lagoon,” he tells me, referring to the massive saltwater lagoon on South Africa’s West Coast. Because the group’s statistician, it was his process to analyse the huge quantities of information the group collected. And underneath the steering of ornithologists, he revealed many scientific papers from that information.

Welcome, comradeski!
Among the many annual guests to the lagoon are numerous wader species that make the long-haul flight (a cool 30,000km spherical journey) from their breeding grounds in Russia’s barren, frozen tundra to vacation by the white sandy seashores and turquoise waters of Langebaan. And the papers that adopted on the birds didn’t go unnoticed by the Soviet Union’s Academy of Sciences. In time, an invite from the Soviets landed on Underhill’s desk and he joined the expedition that might change the course of his profession.
“Keep in mind,” he recollects, “that statisticians are alleged to sit of their workplaces analysing the info that different folks accumulate. I used to be desperately fortunate to be the one that acquired the invitation to affix the expedition to the tundra. The tundra was not the place the typical particular person would decide to go on trip. It was powerful and demanding fieldwork, however it was outside and it was indescribably stunning. That journey to the tundra, 30 years in the past, modified my life.”
Again within the RSA
Returning dwelling, Underhill switched the main focus of his analysis.
Beforehand he had primarily used his statistical experience to unravel mathematical issues, however now he needed to make use of it extra to reply organic questions that might contribute to a greater understanding of nature and, in the end, its conservation.

He started plotting to determine a unit that might let him do that for the good thing about birds. And earlier than the yr was over, he’d launched the Avian Demography Unit. With extra biology college students within the unit learning a variety of animals, its title modified to the Animal Demography Unit, or ADU because it turned typically identified. In 2005, the ADU launched the Digital Museum.
Priceless database
As a substitute of organic specimens on cabinets or in bottles, like in conventional museums, the Digital Museum collects, digitally shops, organises and analyses digital data of animals, fungi and crops from sightings recorded throughout Africa. The data date to 1726 and embrace databases of dragonflies, birds, mushrooms, fish, scorpions, frogs, bushes and rather more.
As we speak the museum is co-managed by UCT’s FitzPatrick Institute of African Ornithology and the Biodiversity and Improvement Institute, which Underhill based in 2015. Underhill’s institute is impartial of UCT and goals to foster analysis and group motion in biodiversity conservation in addition to social growth.

The data are digitally saved and organised within the Digital Museum. In April this yr, its servers narrowly missed destruction in the course of the fires that ravaged Desk Mountain. However backups are saved in off-campus databases — a significant file that lets researchers observe species’ actions and inhabitants numbers. It helps researchers detect modifications out of line with the pure cycles. They’ll then sound the alarm, warning authorities departments, conservation businesses and analysis teams in order that they can reply, hauling species away from the precipice of extinction.
Treasure trove
Underhill credit citizen scientists with gathering a treasure trove of biodiversity information, a large number of fragments of knowledge that assist skilled researchers with their work.
“We construct the jigsaw puzzle of biodiversity from all of the items, and remodel hundreds of thousands of bits of information into data that might be acted on,” Underhill explains.
He encourages folks to open their eyes and really discover and respect the unbelievable life round them. He causes that by partaking folks’s fascination with nature, they usually tend to worth and shield it.
African oystercatchers live to tell the tale the sunny seashores of southern Africa. They’re monogamous and might mate for all times. {Couples} share parenting tasks and even as soon as their chicks can fly they need to hold feeding them. They feed their chicks till their little beaks turn out to be sturdy sufficient and so they have mastered the strategy of opening up the mussels and limpets they eat themselves. Regardless of greater than 60% of African oystercatcher eggs not surviving to hatch at their breeding stronghold on Robben Island, African oystercatcher populations are secure and stay a species of least concern on the Worldwide Union for Conservation of Nature purple record since they moved there from the near-threatened in 2017.

“Nature” doesn’t essentially seek advice from the nice outside. Citizen science could also be about figuring out the gecko in your kitchen ceiling, the beetle in your flower pot or the birds ingesting nectar in your backyard. This was very true throughout final yr’s Covid-19 lockdown, when a deluge of “at dwelling” entries poured in. They might show precious, serving to Underhill and his workforce higher perceive how wildlife makes use of city areas.
How does it work?
It’s simple to contribute to the institute and the unit’s tasks. Citizen scientists usually snap photographs of organisms and add them with the small print of the place and once they discovered them. Some specifically skilled citizen scientists catch and launch birds to collect details about birds’ well being, dimension, weight and moult stage.
They put a hoop with a singular code round a chicken’s foot, so it will probably be recognized and data about it collated if the chicken is recaught. This data is precious for understanding how local weather change is affecting birds’ pure actions and well being.
Although African oystercatchers are charismatic, vibrant and straightforward to identify, their cryptic eggs and chicks are usually not. (Photos: Itxaso Quintana [left] and Rio Button [right]).Behind the scenes, the institute’s researchers handle the info collected, add historic data and analyse it, becoming a member of the dots and giving context and intending to the work of an ever-growing group of citizen scientists.
Staying related
Underhill, a spry 74-year-old who’s lively on Fb and Instagram, delights in piquing curiosity about nature amongst his military of citizen scientists, associates and followers. “There aren’t any silly questions,” he reckons, and enthusiastically engages with queries, large and small.
He hosts occasions, sends newsletters and holds conferences to maintain his group of greater than 2,000 citizen scientists up thus far with recent developments. And there was little let-up for Underhill in the course of the lockdown. He initiated Biodiversity and Improvement Institute digital citizen scientist hours and occasions on-line. Visitor audio system, from Siberia to Seychelles, offered on matters spanning the whole lot from seabirds to seahorses, and citizen scientists from throughout Africa attended religiously.

Recent tips
Underhill embraced bleeding edge blockchain know-how, partnering the Biodiversity and Improvement Institute with the tech start-up Wildcards, a conservation fundraising organisation.
In lower than a yr, Wildcards raised $18,000 for the institute. The platform lets funders help the institute by changing into the guardians to tokens of digital animal playing cards of species the institute helps preserve in actual life. Each month, guardians make subscription donations to the institute. The institute will use these crypto-currency windfalls to proceed its work.
Jason Smythe, a Wildcards co-founder, explains: “Wildcards goals to facilitate the intersection of economics, altruism and group to interrupt down the normal boundaries to conservation fundraising.”
Highly effective pressure

African Blue Pansy (Junonia orithya madagascariensis) butterflies are transferring west. The shift of their distribution has been detected due to the contributions of citizen scientists to the Digital Musuem’s LepiMAP venture.
Underhill believes the citizen science group is a pressure to be reckoned with. The info it collects is of actual scientific worth and it facilitates conservation planning and the setting of priorities. By getting concerned in hands-on tasks, folks turn out to be alert to modifications in habitats. This fosters civic consciousness, particularly because the locations the place we used to search out birds and butterflies disappear.
Underhill desires to strengthen teams who’re conscious of the worth of the atmosphere and motivated to guard wildlife and wild areas. He needs to provide them a approach to take part in conservation science.
A very good instance of that is LepiMAP, a Digital Museum citizen science venture that has assisted researchers to detect a westward shift in lots of butterfly species in South Africa. Might the transfer be linked to local weather change, pesticides, air pollution or predators?
Institute and unit researchers are investigating.

Because it occurs, the databases are backed up off campus. (Photograph: Provided by the Biodiversity and Improvement Institute)
Success story
However biodiversity monitoring will not be solely about recording the demise of species and scrambling to stave off extinctions — as essential as this work is. It is usually about detecting the restoration of species.
Throughout my summer season monitoring African oystercatchers, I stumbled sooner or later, practically stepping on a monstrously massive mole snake, an egg-shape bulging simply behind its neck. The snake was close to a nest the place, on an earlier go to, I had seen an egg.
I spied many extra such fats mole snakes on Robben Island. Usually they had been trolling above the excessive tide mark, close to the place I had beforehand discovered different oystercatcher nests, inconspicuous among the many shells with their cryptic, mottled eggs. As a rule, the nests had been empty — and this, lengthy earlier than the chicks had been because of hatch. Certainly, we subsequently established that lower than 40% of eggs hatched.
I feared the island’s many mole snakes had been breakfasting on eggs, tipping the fragile steadiness of nature and sending African oystercatchers spiralling again to close threatened standing, the place that they had languished from 2004 to 2016, and in addition within the Eighties. However, it seems, with the angle of twenty years of Robben Island breeding figures and citizen science information from the Biodiversity and Improvement Institute, that the African oystercatcher is doing properly. Populations are on the rise and the birds are spreading their wings, because it had been — the areas the place they’re discovered have been increasing.

So what was that approach Underhill taught me for pinpointing nests — the one he additionally wowed the Russian researchers with 30 years in the past?
Properly, it really works like this: While you spot a chicken sitting far-off, hopefully on its eggs, keep in mind that as quickly because it sees you, it’s going to attempt to lure you away. So, fast as a wink, you discover factors and objects within the panorama and draw an imaginary line by them and the chicken. Then follow that line.
Sooner reasonably than later the chicken will see you coming and check out to guide you astray. Go slowly and punctiliously. The eggs are very well camouflaged and also you don’t wish to step on them.
