The sea urchin that won’t die

In the freezing, inhospitable water off Norway’s Svalbard Archipelago, a wounded sea urchin the size of a walnut staggers across the seafloor. Its precious gonads and half its shell are missing, yet it clings to life for more than 43 hours. Lucky for scientists, they caught the nearly dead urchin on camera, allowing them to witness, for the first time in the wild, sea urchins’ stunning capacity for survival… Read the full story over at Hakai.

Citizen science helps assess the state of India’s birds

The State of India’s Birds 2020 takes into account 867 of the 1,333 species that have been documented in India on eBird. According to the assessment, species adapted to living alongside humans are doing well, others not so much. Overall, migratory shorebirds and raptors have been hit the hardest. Read the full story here.

The art of making paper birds

A hummingbird hovering in the air laps up nectar from a coneflower. Newborn bulbul chicks beg their mother for food. A male kingfisher offers fish to a female kingfisher, perched on a mossy piece of driftwood. These are some of the natural history moments captured by artist Niharika Rajput in her lifelike paper sculptures.

I interviewed the artist for Atlas Obscura about her artistic process and all things birds.

Plastic-free seals

Whales, seabirds, turtles, crabs, and worms—all kinds of marine animals are afflicted with plastic pollution. But seals living in the eastern Canadian Arctic seem to have so far escaped this modern plight. When scientists examined the stomach contents of the Arctic’s ringed, bearded, and harbor seals, they found krill, fish, kelp, roundworms, and even rocks. But not plastic…

A burning desire to save birds

A birder and a phillumenist have teamed up for an art project that combines their interests and carries a conservation message.

Hobbyist birder Mitul Patel has a day job as the art director at an advertisement agency in Mumbai and matchbox collector Asif Kureshi is an independent graphic designer based in New Delhi. A while back, the two friends found themselves brainstorming ideas on bird-themed art and that’s how 12 endangered birds ended up on matchbox covers in a series called ‘The Burning Birds of India.’

Of fiddler crabs and their fiddles

A male fiddler crab’s massive pincer serves a clawful of purposes. It’s useful in fighting off males and wooing females, but being big and heavy also makes it a liability. Fortunately, if caught by a predator, the crab can shed this hefty claw and scuttle to the safety of its burrow. Research shows this escape act might be facilitated by the fact that, after losing the claw, the crab runs almost a third faster.

Fish eggs hatch after being pooped

Found in temporary desert pools and mangrove swamps, some species of killifish can go without water for weeks at a time. And their eggs are no different: no water, no problem! Now, scientists have found that the eggs of two killifish species are so hardy, they can withstand being digested by birds, too. The finding may be the first firm evidence supporting an idea that has long held sway in scientific circles—that birds disperse fish.

London’s wild side

There is a nip in the air and gusts are shaking the trees awake. The morning sun is hidden behind an overcast sky whose sullen grey is mirrored by the lake stretched out before me. As I scan the Serpentine’s waters, something familiar catches my eye. A rufous-and-cream bird with a feathered ruff around its head is surfing the lake, preening its feathers. It’s a great crested grebe, a bird that has eluded me for a year. And here it is, smack in the heart of London.

When the grebe finishes preening it swims in a frenzy, as if looking for something—wait, there’s another nearby. The two swim towards each other and, before I know it, erupt into a courtship dance. 

Read about the pair of dancing grebes and other urban wildlife of London here.

Finding seashells on the seashore

The smell of sea hangs thick in the air as we gather round and listen to the dos and don’ts. “Don’t pick up anything even if it seems beautiful,” Sejal Mehta tells a motley group of students and professionals. “It might sting you and you might die.”

We have assembled to spot wildlife in a metropolis where the uninitiated might not expect to find any. After all, the city of dreams, Mumbai is famous for its Bollywood ‘stars’ – not the stars that live or wash up on its shores. The city is better known by its dabbawalas clad in white than the otherworldly creatures decked up in shells or tentacles. But this is why we are here. A citizen science initiative called the Marine Life of Mumbai has organized a shore walk to bring the city’s most underrated stars into the spotlight.

Mumbai’s unexplored shores have more than 50 species of crabs, Pradip Patade, the co-founder of Marine Life of Mumbai, tells me. Patade’s day job as a watersports instructor had primed him to launch the initiative. Every day at work he would come across creatures of all sorts on the beach and in the open waters. But 2013 became a turning point for him.

Patade was on lifeguard duty when several people were stung by stingrays, which come to shallow waters to give birth and sting when stepped on. Patade, shocked by the lack of knowledge about these animals, wanted to do something. So, he started sharing his marine finds on Facebook. Years later, the naturalist teamed up with two researchers and thus, Marine Life of Mumbai was born in February 2017. It started out as an online repository of information but then Patade and his team thought that taking people along on walks would make more of a difference.

Two years and several shore walks later, Marine Life of Mumbai has filed 1300 records of 315 species on the citizen science app iNaturalist. Meanwhile, its band of volunteers has continued to expand. The volunteers help out as resource persons for the walks, Patade says, or with identifying species, writing content for social media, and running the website.

Writer and editor Sejal Mehta has been contributing to Marine Life of Mumbai for over a year. The intertidal zone, exposed at low tide, was completely new to her when she joined. Until then, Mehta’s notion of sealife was “dolphins and whales.” Today, she is introducing us to the intertidal zone and its denizens — with metallic sea stars dangling from her ears.

Life on the city shores

Mumbai’s coastline has a variety of habitats – sandy shores, rocky shores, mudflats and mangroves, Mehta tells us. Juhu beach, where we are, has three of these – sandy, rocky and muddy – along its six-kilometre stretch. I am thinking we are in for a treat when Patade hints at the unpredictability of wildlife. You don’t always see a tiger on a tiger safari, he quips.

Just moments later, though, he points at what looks like abstract sand art. Tiny orbs of sand are strewn all around us, some stacked atop each other into miniature sandcastles. The work of sand bubbler crabs, which live in burrows and come out to feed at low tide, we are told. The orbs and castles that dot the beach are essentially sand grains that the crabs have filtered for nutrients.

We didn’t see the crabs as they remained hidden in their burrows – thanks to the big friendly giants walking overhead. But now, it became impossible for us to walk without thinking of the many lives in the sand below our feet.

image-2Patterns indicate the presence of sand bubbler crabs 

As we try keeping up with Patade, we spot a pile of hermit crabs arguing over shells. When a hermit crab grows out of one shell, it has to find – and often fight – for another, bigger shell. The shell it abandons becomes available for a smaller hermit crab to move in. But without one, this soft-bodied crab is seafood for the hungry crows and shorebirds lurking nearby. Empty snail shells are prime real estate here, we realise as we leave the hermits to themselves.

And soon, we chance upon a sea anemone. It would fit on the palm of your hand, except that stinging cells line its tentacles. Waves come and go but the anemone remains firmly anchored to the spot – only its tentacles dance in tune with the ebb and flow. Some anemones form symbiotic associations with other animals such as hermit crabs, Mehta volunteers. But the most amazing thing, she says, is that they can multiply by splitting into two. Anemones can also reproduce sexually.

Among the rocky outcrops off the sandy shore, we find barnacles attached to rocks, a baby octopus swimming in the tide pool, a moray eel seeking cover, colourful sea sponges on jagged rocks, crabs hidden in crevices, camouflaged sea stars, and tiny porcelain crabs dressed in stripes.

Mumbai-based photographer Pratha Narang says she didn’t know that a stone’s throw from her home, you could find so many small and wonderful creatures. “I was overwhelmed by their presence.” Other participants echo this. Teacher Kapil Joshi says he was amazed by the knowledge of the Marine Life of Mumbai group. “I am going to share it with my students at school.”

As the tide returns, we reluctantly leave the company of the weird and wonderful behind. No one was bitten or stung but we all left starstruck, as it often happens in Mumbai.

This moth supplements its diet with bird tears

In the forests of Brazil lives a moth that drinks tears of birds. It perches quietly at the back of an antbird at night – when the bird’s not very active – and uses its long, flexible proboscis to lap up its tears. Don’t believe me? See for yourself!

*I’m not crying; there’s something in my eye*

Egg theft might cause seabird decline

Among the 36 Lakshadweep islands dotting the Indian Ocean, one is particularly famous for its bird life. Pakshi Pitti is a flat sandbar that several species of seabirds come to for breeding. Devoid of predators such as rats and cats, and even humans, it is the perfect place for these birds to nest in.

Except, year after year fisherfolk from the nearby populated island of Kavaratti come to Pitti and plunder its wealth of seabird eggs. On every visit they make, they collect 14%–45% of the eggs. About 72% of the islanders of Kavaratti are involved in poaching and trading eggs from Pitti, showing that the network is quite vast.

The eggs are sought for their supposed medicinal properties, and their trade, scientists fret, could have a huge impact on the island’s seabirds, especially terns, whose numbers have plummeted from 20,000 in the mid-1900s to 970 in 2014.

Pitti was declared a bird sanctuary and afforded legal protection to stop this age-old practice of egg consumption. But a lack of regulation is defeating that purpose.

Little auks slurp like fish

The little auk is a small seabird that would fit comfortably in the palm of your hand. At only about 150 grams, this featherweight bird eats 20% of its body weight in prey each day. And this takes some underwater hunting skills. Diving up to depths of 27 meters, the bird spots and slurps its prey, much as fishes do. Read more about the world’s only slurping seabird here in my first piece for Hakai magazine.

How are India’s birds faring?

About 1,500 of the world’s 11,000 bird species are on the verge of extinction, thanks to human activities like agriculture, logging and hunting, according to a report by BirdLife International.

I decided to dig deeper and look at the status of birds in the context of India. After sifting through factsheets after factsheets, here’s what I found: Close to 90 of the 1,200-odd bird species are on the verge of extinction in the country. Of these, 16 are critically endangered, 21 are endangered and 52 are vulnerable. These include not just birds found only in India (or ‘endemic species’) but also ones that migrate to the country.

An additional 74 are near-threatened – they might soon be assigned one of the three threatened species status. Vultures, bustards, eagles, hornbills, woodpeckers, storks are all in trouble. So are robins, thrushes, buntings, babblers.

The state of a stout, white and brown bird, the great Indian bustard, is especially worrying. “It really is in a bad way,” Tris Allinson of BirdLife told me. “It could well be the planet’s next extinction,” he added. A few hundred individuals of the species remain. Though it was declared critically endangered in 2011, not much has changed in terms of protecting its grassland home. Wildlife sanctuaries have been established but a commitment to protecting India’s wider landscape of grasslands is still awaited. Since bustards tend not to remain within protected area boundaries year-round, grasslands outside sanctuaries need to be urgently protected by law.

Things have also become worse for other birds in India – several have been moved to higher threat levels. The endemic Narcondam hornbill (Rhyticeros narcondamii) was vulnerable by 2008 and was uplisted to endangered in 2009; another endemic species, the Manipur bush-quail (Perdicula manipurensis) went from vulnerable in 2012 to endangered in 2013; and the migratory steppe eagle (Aquila nipalensis) was of least concern until 2013 and was uprated to endangered in 2015.

But there’s one recent downlisting that stands out: the endemic forest owlet (Heteroglaux blewitti) was critically endangered until 2016 and was moved down to the endangered category in 2017.

Bird Ballet

I had a dry spell for the whole of April. But the start of May has brought some good news – a new byline. This is a piece that’s very close to my heart because it is my first true attempt at nature writing. (I am a science writer, so of course I backed it up with science.) And to top it all *pause for effect* it carries some of my photographs. This story was fun to write as it brought together all the things I like – writing, writing about science, photography and birding! Isn’t that great?

So without further ado, let me quickly tell you what’s it about and then you’re free to go read it. (Or to keep the surprise element intact, skip to the end). It’s about Rosy Starling – a lesser-known species of starling that also murmurates like its European counterpart but hasn’t got as much attention. Earlier this year I went birdwatching at a lake not very far from where I live. And I found this huge conglomeration of rose-coloured birds resting on trees there. When dusk fell and it started to pour, the flock of birds took off and started swirling through the sky. It twisted and turned, split into smaller flocks and merged back again, singing all this while. The flock then returned and rain downed on the trees, preparing for a long night.

I describe this in a lot more detail for JLR Explore. Go, check it out.
