For many of us, the arrival of the Indian monsoon is marked by dark clouds, petrichor and the first sigh of relief after months of heat. Across India’s forests, wetlands, fields and cities, the rain also signals a seasonal transformation in the lives of animals.
The monsoon softens the soil, fills streams and wetlands, triggers breeding cycles for wildlife and brings food and shelter to landscapes that may have remained dry for months. For some species, it is the season to emerge from underground. For others, it is time to mate, feed or migrate.
Along with the widespread hues of green, there’s a lot happening to life in the forest when rains arrive. For wildlife enthusiasts, monsoon is a splendid season to observe some of the most remarkable species in the wild.
The Animals that Wait for the Rain
Few creatures embody the monsoon quite like India’s amphibians and reptiles. With the arrival of the rains, increased moisture, temporary pools and an abundance of food create ideal conditions for many species to become more active, while amphibians in particular begin calling and breeding. The Western Ghats come alive during this season, with frogs emerging from their shelters and reptiles becoming more visible across the landscape.
Deep beneath the forests of the Western Ghats lives the purple frog (Nasikabatrachus sahyadrensis), an endemic and endangered species that spends almost its entire life underground. Only when the rains arrive does it emerge for a brief but vital breeding period before disappearing beneath the soil once again.
The Malabar gliding frog, another exclusive amphibian belonging to the Western Ghats, also makes the most of the season, using its broad webbed feet to glide between trees and building foam nests right above water bodies surrounded by them, where newly hatched tadpoles can eventually drop into.
Even animals we rarely get to notice in other seasons become more visible during the monsoon, when the abundance of moisture and prey creates ideal conditions for many elusive species. The venomous snake Malabar pit viper, for instance, becomes particularly active on rainy nights, when frogs — one of its primary prey — are abundant around streams, ponds and other wet habitats. Nilgiri caecilian, a limbless amphibian that spends much of its life underground, also emerges more frequently as rain softens the soil, bringing it closer to the surface alongside the earthworms, termites and other small soil-dwelling creatures that form part of the caecilian diet.
For these species, the monsoon is the signal that life can begin again.
Even the tiny red velvet mites that some of us may have seen around our homes, appear on the soil just before the season of rainfall begins.
The Birds that Herald the Rains
Some of India’s most recognisable monsoon wildlife are its birds.
The pied cuckoo, or jacobin cuckoo, has perhaps the strongest cultural association with the Indian rains. While populations in southern India are resident, the said bird appearing across central and northern India during summer are migratory, travelling from Africa to the subcontinent to breed. Their arrival in late May and June often precedes or coincides with the advancing southwest monsoon, earning them a place in generations of stories and traditions as harbingers of rain. Satellite tracking has even recorded a pied cuckoo travelling around 5,000 kilometres from Dehradun back to the coast of Somalia after the breeding season!
Across newly filled wetlands, species such as the pheasant-tailed jacana, a medium sized wading bird, along with large avians like Asian openbill and sarus crane, fly from vast distances to benefit from the seasonal abundance of water and food.
A widely distributed bird called the baya weaver, meanwhile, enters its breeding season with the rains. Across India’s rural landscapes, males begin constructing hanging nests from grass and plant fibres as part of their courtship. Halfway through, they try to catch the female attention so they could come and have a look. When one picks the nest she finds conveniently designed, she joins the male to finish making it.
And then there is the unmistakable sight of the Indian male peafowl displaying its spectacular plumage against a rainy backdrop. Many associate peacocks opening their feathers to indicate the season of rains, but its famous dance is actually linked to its breeding season, which happens to coincide with the monsoon.
When the Rain Brings Wildlife Closer To Us
The same rains that awaken our forests also reshape urban neighbourhoods and farmlands.
Flooded burrows, waterlogged fields and overflowing water bodies often force reptiles and other animals to seek safer ground. Newly formed pools and connected waterways can also expand where wildlife is able to travel.
That’s when Wildlife SOS’s Rapid Response Units find themselves responding to calls coming in from homes, office campuses and agricultural fields.
Rescue data reflects this seasonal shift during monsoons, with reptiles topping the list of unexpected encounters. Across Delhi, Agra, Vadodara and Jammu & Kashmir, nearly 5,000 reptiles were rescued during June–September between 2021 and 2025, accounting for roughly half of all recorded rescues during these four months of rainfall. Snakes are forced out of their burrows once they get flooded, making them seek dry and dark shelters. Somehow, during this mission, several end up in places that are occupied by human beings, which requires both panic management and knowledge dispersal.
Vadodara: when the waters rise
In Vadodara, the arrival of the monsoon brings with it an annual phenomenon: as heavy rains swell the Vishwamitri River and flood its surroundings, mugger crocodiles are often displaced from their usual habitats and find their way into agricultural fields, roads and other human-dominated spaces. Wildlife SOS has responded to such rescue alerts year after year. In July 2022, the team rescued a 12-foot-long mugger crocodile from a farm field near Vadodara, one of the largest crocodiles we have ever rescued.
Agra and Uttar Pradesh: a season for snakes
Agra recorded the highest number of monsoon reptile rescues among the four regions that we operate in, with over 2,000 rescues made between 2021 and 2025.
Cobras, rat snakes and wolf snakes were among the species most frequently rescued from this region during these months, alongside common sand boas, monitor lizards, pythons and kraits. July consistently emerged as the busiest month for many of these rescues.
Sometimes rescues unravel facts in surprising places. In Etawah, a city around 120 kilometres away from Agra, Wildlife SOS and the Uttar Pradesh Forest Department were beckoned to rescue 25 newly hatched Indian rock pythons from an unused tubewell. Indian rock pythons lay their eggs during March-April with the babies ready to come out during the monsoon months from July to September which helps them with abundant thriving prey easily.
The monsoon belongs to wildlife too
From a rare and elusive purple frog to the pied cuckoo, a bird that many believe to be the harbinger of rains, India’s monsoon reveals a remarkable side of the country’s biodiversity.
But it also reminds us that wildlife responds to various seasons as per their life cycle survival. Their natural landscapes are fast becoming cities, farms or factory lands. Change in ecology impacts climate, pushing animals to face challenges as temperatures rise, habitats transform, and unusual scenarios of finding them in urban landscapes increase.
A snake in a garden, a crocodile in a flooded field or a python in an unexpected corner may be startling, but these encounters often find their roots in animals simply responding to their changing environment.
The safest response is to contact trained wildlife rescuers or the local forest authorities. By responding with caution and compassion, we can help ensure that India’s wild residents remain safe and continue to thrive.
If you encounter wildlife unexpectedly near you, please contact trained rescue professionals immediately. If you wish to support Wildlife SOS’s Rapid Response Units and help rescue wild animals in distress, please consider making a donation.
