Narmada Valley dry deciduous forests

Indian Grey Hornbill sightings on July 18 coincided with peak monsoon fruiting — sacred figs and cluster figs now ripening across the city. The birds are drawn to this abundance not by accident; hornbills and figs have evolved one of the forest's most essential mutualisms — as the birds feed, they disperse seeds far from parent trees, a process that drives forest regeneration across generations.Timing compounds the significance. July marks nesting season for these hornbills, and they shelter in cavities within the same old fig trees that now fruit. A single mature tree becomes both pantry and nursery, sustaining breeding pairs precisely when energy demands peak. The synchrony between fruiting and breeding is no coincidence — it is the ecology that built the forest.

Granite Ghosts (Bradinopyga geminata) arrived at Pashan Lake on July 9, joining over 20 odonate species recorded in the first ten days of the monsoon—a pulse of dragonflies and damselflies triggered by seasonal rains. These small, compact dragonflies breed only in seepage that flows over bare rock, and odonatologists have long used them as a landscape moisture gauge. When Granite Ghosts appear, you know the groundwater has risen all the way to the stone.The diversity this week speaks to the monsoon's power: alongside the Granite Ghosts came Common Picture Wings, Lesser Emperors, Scarlet Skimmers, and species from every dragonfly lineage present here. Ninety-six odonate records in the past forty-five days mark the seasonal transformation from dry-season scarcity to summer abundance. For now, the landscape is wet all the way down.

Four cuckoo species converged here in late June and early July—a striking ecological moment that reveals the precision of brood parasitism timed to monsoon rhythms. Asian Koel, Common Hawk-Cuckoo, Grey-bellied Cuckoo, and Fork-tailed Drongo-Cuckoo were recorded across the region during this brief window. Each species has evolved to time its breeding to match the nesting peak of its specific host birds, a behavioral synchronization refined over millennia.The Hawk-Cuckoo's call—a loud, whistled "brain-fever"—has been a signature of the Deccan monsoon rains for centuries, its arrival marking the start of the wet season in local tradition. This year it shared the stage with three companions, each pursuing the same parasitic strategy but targeting different host species. The simultaneous presence of all four speaks to the robustness of the monsoon pulse itself, the surge of insect availability and nesting activity that draws these specialized brood parasites to the region year after year.

The coast is already rising. Monsoon winds are pushing water inland days before the rains arrive — the tide stands nearly 10 centimeters above its predicted level, flooding the intertidal zone longer than the spawning rhythms of fish have tuned to expect. Local fisherfolk recognize the signal at once: it is time to pause, to let the sea move through its own cycles undisturbed.Over the past two months, more than 200 observations across 121 taxa have been logged from this coastal reach. Eucalyptus dominates the tallied records, a reflection of the introduced plantings that now make up nearly a quarter of the observable flora here. Among them are native species — trees, birds, insects, and herbs bound to the region's ecological history — but the landscape they inhabit is increasingly composed of species brought from elsewhere. The rhythm of the tides waits for no arbor; the question is whether the creatures that depend on that rhythm can adapt quickly enough.

Over the past two months, forty-two butterfly species have turned up across the city's green patches — a striking diversity that speaks to pockets of refuge persisting even as development accelerates. Among them was a sighting of the Crimson Rose (Pachliopta hector), a protected species typically found in more open countryside, on June 7 — a reminder that urban butterfly populations can include species of regional conservation concern.That same month, an Ashoka tree (Saraca asoca) came into flower on June 24 — a species planted at temples for millennia across the region, and now threatened by bark harvest for traditional medicine. The persistence of both the butterfly and the tree here, however precarious, suggests that intentional conservation and habitat preservation within an expanding city can still matter.

The air over Narayan Peth sits heavy and bright in the middle of summer. In the gardens and along the roadsides, wherever a citrus tree grows, look closely at the leaves. Near the tips of young shoots, on the smooth upper surface of a single leaf, you may find a pale yellow egg, about the size of a pinhead, sitting alone. It was placed there by a lime swallowtail, and it is the beginning of a new generation.The lime swallowtail is one of the most widespread butterflies in this part of the world. It is a large butterfly, with yellow and black patterning across its wings and a distinctive dark band running through them. In flight it moves with a loose, unhurried wingbeat, and it is often seen in gardens, around flowering shrubs, or drifting along tree lines. But in early summer, the females are doing something more deliberate. They are searching for citrus. Lime, lemon, orange, curry leaf, and the native bengal quince all belong to the same plant family, and all carry the chemical compounds the lime swallowtail needs. A female will land on a young leaf, press her forelegs against the surface, and taste it. She is checking for the right volatile compounds before she commits to laying. If the leaf passes, she curves her abdomen and deposits a single egg, then moves on to the next plant. She will lay dozens of eggs this way, spreading them across different plants rather than concentrating them in one place.The timing matters. Young, actively growing leaves are softer and have lower concentrations of the defensive compounds that older leaves accumulate over time. A caterpillar hatching on a mature leaf faces tougher tissue and stronger chemistry. On a new flush of growth, it has a better start. Summer in Narayan Peth brings heat and, in many gardens, irrigation, which keeps citrus pushing out new leaves even when the rains have not yet arrived in full. The butterfly is tracking that growth. The caterpillars that hatch will go through several distinct stages. Early instars are dark and mottled, resembling bird droppings on a leaf surface. Later instars turn green, matching the leaf they rest on. Both are forms of concealment, but they work differently at different sizes. The caterpillar also carries a structure behind its head called an osmeterium, a forked orange gland that it can extend when threatened, releasing a sharp, unpleasant smell. It is a last resort, but it works against some predators.The lime swallowtail does not live in isolation here. The common mormon swallowtail uses the same citrus host plants, and both species can be found laying on the same trees during the same weeks. There is overlap but not direct competition in the strict sense: each female is selecting individual leaves, and a tree in active growth produces enough new foliage to support both. The shikra, a small hawk present in this area, takes large insects and could take a butterfly on the wing, though the swallowtail's erratic flight makes it a difficult target. More consistent pressure comes from birds like the greater coucal, which moves through dense vegetation and is capable of taking caterpillars from foliage. This is part of why the egg-scattering behavior matters. A female that lays all her eggs on one plant loses everything if a forager works that plant thoroughly. Distributed eggs mean distributed risk.The plain tiger butterfly and the lemon migrant are also moving through gardens right now, each tied to different host plants, each running its own cycle through the heat. The lime swallowtail's cycle is simply the one written on citrus leaves. If there is a citrus tree near you, or a curry leaf plant in a pot, run your eye over the youngest leaves at the growing tips. The egg, if it is there, will catch the light slightly differently from the leaf surface around it, a small pale dome sitting on green.

The air around the cluster fig carries the sweet scent of ripening fruit, thick and cloying in the summer heat near Narayan Peth. Small green spheres hang directly from the trunk and main branches, clustered in dense bunches that give this fig its name. The tree's unusual fruiting pattern draws attention upward, where movement flickers among the leaves.Coppersmith barbets work the ripening figs with methodical precision. These compact, green birds with their distinctive red caps and yellow throats position themselves at the fruit clusters, gripping the bark with strong feet while they feed. Their heavy bills, perfectly sized for the small figs, allow them to pluck and swallow the soft fruit whole. The barbet's monotonous tuk-tuk-tuk call, like a hammer on metal, punctuates the feeding as birds communicate across the canopy. During summer, when their young have recently fledged, these calls intensify as parents guide juveniles to productive feeding sites.The cluster fig's summer fruiting provides crucial nutrition during the barbets' most demanding season. Unlike other figs that fruit on branch tips, Ficus racemosa produces its crop directly from the trunk and major branches, making the fruit accessible to cavity-nesting birds like barbets that prefer the security of thick wood nearby. The timing aligns precisely with the barbets' breeding cycle. Young barbets, recently emerged from nest holes excavated in dead wood, require high-energy food to build strength for independent life. The figs' soft flesh and concentrated sugars deliver exactly what growing birds need. Rose-ringed parakeets and Indian gray hornbills also exploit this bounty, but the barbets' smaller size allows them to access fruit clusters that larger birds cannot reach. The fig benefits from this relationship through seed dispersal. Barbets digest the flesh but pass the tiny seeds unharmed, depositing them across their territory as they move between feeding and roosting sites.House crows gather beneath the fruiting trees, waiting for dropped figs and competing with the barbets for access to lower branches. The invasive monkey pod trees nearby offer alternative perches, but their imported pods cannot match the nutritional timing that the native cluster fig provides. Asian koels, now calling from the canopy above, will soon shift their attention to these same fig trees as their own breeding season progresses. The steady tuk-tuk-tuk continues, closer now, as a barbet works a cluster just overhead, each strike of its bill releasing another wave of that sweet, heavy fragrance into the warming air.

The air carries the sound of leathery wings before dawn in this stretch of Maharashtra. Indian Flying Foxes move through the canopy with heavy wingbeats, their meter-wide spans catching the first light as they return from night foraging. These large fruit bats are settling into their breeding season now, and their hunger has intensified. They need more than fruit to sustain the energy demands of courtship, mating, and eventually nursing young.The Indian beech trees scattered across this landscape provide exactly what the flying foxes require. These native trees bloom in dense clusters of small white flowers, each one heavy with nectar and pollen. A single flying fox can visit dozens of blossoms in one feeding session, its long tongue probing deep into each flower. The bat's face emerges dusted with pollen, which it carries between trees as it feeds through the night. What begins as the bat's search for high-energy food becomes the tree's reproductive strategy. The Indian beech depends on these large pollinators to move genetic material across distances that smaller insects cannot cover.This relationship intensifies during the flying fox's breeding season because pregnant and nursing females require nearly twice their normal caloric intake. The timing aligns perfectly with the beech trees' peak flowering period in early summer. The bats' increased foraging pressure actually benefits the trees by ensuring more thorough pollination across the population. A pregnant female flying fox may visit over a hundred flowers in a single night, methodically working her way through multiple tree crowns. The seeds that result from this pollination will mature and drop months later, when the bats again need concentrated nutrition for weaning their young. The flying foxes then become seed dispersers, carrying the large beech seeds away from parent trees and depositing them in their droppings at distant roost sites.The invasive monkey pod and flamboyant trees that now dominate parts of this landscape cannot replace what the Indian beech provides. Their flowers bloom at different times or offer different nutritional profiles. The native partnership between flying fox and Indian beech has been refined across thousands of breeding seasons, each species responding to the other's needs with precise timing. Listen for the soft whistle of wind through bat wings in the early morning darkness. The sound grows fainter as they settle into day roosts, but their night's work continues in the pollen-dusted flowers and the seeds already forming in the warming air.
