Here a mother elephant with twine, as seen in Corbett. Twins in elephants are not just rare; they are a fascinating lesson in population dynamics. In ecology, scientists often describe species using two reproductive strategies: r-selected and K-selected. These terms come from population growth equations. “r” represents the intrinsic rate of population growth - how fast a species can multiply. “K” represents the carrying capacity of an ecosystem - the maximum population that the environment can sustainably support. Species that follow the r-strategy focus on rapid multiplication. They produce many offspring because survival chances are low. Think of insects, frogs or many fish. Their formula is simple: more babies = better chance that some survive. Elephants belong to the opposite category; K-selected species. These animals live near the carrying capacity (K) of their habitat, so competition for resources is high. Instead of producing many young, they invest heavily in very few. For elephants: Pregnancy lasts nearly 22 months Usually only one calf is born Mothers and herds spend years protecting and raising that calf Population growth is naturally slow That is why twins in elephants are so extraordinary. In a species evolutionarily designed for “few offspring, high investment,” producing two calves at once is almost an exception to the rule. In r-selected animals, twins or multiple young are common. In elephants, even one calf is a major biological investment. Two together become a remarkable event in the story of life history and population dynamics.

Do you know there are now just around 150 great Indian bustards remaining in the wild. Meanwhile, against the odds, hope is taking shape in the deserts of Jaisalmer. The conservation breeding programme for the critically endangered Great Indian Bustard has now crossed an important milestone, with the captive population reaching 86 birds. Remarkably, recent chicks have been produced through artificial insemination: a major scientific breakthrough in India’s wildlife conservation efforts. From protected breeding enclosures to preparations for future rewilding in the Thar, this is conservation science working against time. And perhaps one of India’s most important species recovery stories unfolding right now. #GreatIndianBustard #Conservation #Jaisalmer #Wildlife #TharDesert #EndangeredSpecies #ConservationSuccess

So today I found something interesting in our national park. Sharing with all.

How life begins. At the Rushikulya river mouth in Ganjam, Olive Ridley sea turtle hatchlings have begun their remarkable journey to the sea. One of nature’s most heartwarming spectacles. After nearly 45 days of incubation, thousands of tiny hatchlings are now emerging from the sand and instinctively racing towards the Bay of Bengal. This season alone lakhs of eggs were laid along the coast, turning the beaches into a crucial nursery for the species. The phenomenon called Arribada; a rare mass nesting event where thousands of female Olive Ridleys come ashore simultaneously to lay eggs. The word “Arribada” comes from Spanish, meaning “arrival by sea.” L Female turtles often return to the same coastline where they were born, digging nests in the sand and laying around 80–120 eggs each. Despite overwhelming odds from predators, tides and human disturbances, these tiny hatchlings begin their perilous march to the ocean, a journey guided by natural light and instinct refined over millions of years of evolution. Scenes like these are a powerful reminder of how we share this planet with so many other species. (VC Odisha FD)
