Gujarat's Annual Waterbird Census Documents Dramatic Flamingo Migration Shift
The recently concluded annual waterbird census in Gujarat has revealed a significant redrawing of the winter migration map across the state's wetlands. While overall bird numbers have reached staggering new heights at two key Ramsar-recognized sites, the iconic flamingo—once the visual signature of these areas—has largely disappeared from its traditional haunts.
Record-Breaking Numbers at Traditional Wetlands
The census documented truly remarkable figures at Gujarat's premier wetland destinations. Nalsarovar recorded a historic 6.42 lakh birds, representing the highest count in its recorded history. Meanwhile, Thol Lake posted its strongest performance in 15 years with 74,400 birds. Together, these two internationally recognized wetlands hosted an impressive diversity of species—270 different types at Nalsarovar and 205 at Thol.
"The 6.42 lakh figure was the highest ever recorded at Nalsarovar," confirmed Aradhana Sahoo, Chief Conservator of Forests for Nalsarovar. "Gujarat has witnessed a particularly strong migratory presence this year."
The Flamingo Exodus: From Ahmedabad to Kutch
Amid this abundance of nearly 7.2 lakh birds across both wetlands, flamingo numbers told a different story. With just around 1,622 recorded across both Nalsarovar and Thol—and virtually none at Thol this season—the pink-plumed visitors have largely moved elsewhere. This represents a dramatic decline from historical patterns when Nalsarovar alone would report flamingo congregations exceeding 25,000 during overall bird counts of 1.5 to 2 lakh.
Ahmedabad's loss has become Kutch's gain, as large flamingo colonies are now thriving in the Rann of Kutch region. Foresters documented the presence of approximately 10 lakh flamingos in the Nadabet wetland at the end of January, with improved breeding conditions there appearing to have tipped the ecological balance.
Kutch Emerges as New Flamingo Hub
Experts tracking bird movements across western India confirm that flamingos have shifted their center of activity to Kutch. Unseasonal rainfall helped retain water in parts of the Greater and Little Rann of Kutch, improving vegetation and feeding grounds—key factors for congregation and breeding.
"Large colonies were observed in both the Greater and Little Rann, indicating Kutch has emerged as the principal hub this season," said Uday Vohra, ornithologist and former forest officer associated with multiple census exercises. He noted that while flamingos may still arrive at Nalsarovar in the final leg of the season running until April, current concentrations are firmly established elsewhere.
Observers also reported that flamingos were scarce at other traditional sites including Porbandar and Thane Creek near Mumbai, suggesting the birds are responding to a broader set of habitat cues and breeding opportunities concentrated in Kutch this year.
Forest Department Interventions Boost Kutch's Appeal
Strategic interventions by the forest department have significantly strengthened Kutch's appeal to flamingo populations. In 2020-21, authorities created ten artificial breeding platforms specifically designed to support nesting. Each platform measures 100x10x1 meters and prevents eggs from being washed away during heavy rainfall.
The results have been impressive: subsequent enumeration reported 1.78 lakh greater flamingo chicks, 97,700 lesser flamingo chicks, and 82,900 chicks whose species could not be identified. These conservation efforts, combined with favorable monsoon conditions in 2022, have created ideal breeding circumstances.
"With Kutch offering better water availability, safer nesting sites, and improved feeding grounds, flamingos are prioritizing Kutch over inland wetlands this year," explained a senior forest official.
Reduced Human Activity Benefits Bird Populations
Ornithologists have identified another factor contributing to the surge in overall bird numbers at Nalsarovar and Thol: the absence of tourism activity. Approximately 250 boatmen previously operated at Nalsarovar before boating was suspended following the Harni tragedy in Vadodara in January 2024.
Experts suggest that minimal human interference in sensitive wetland habitats directly leads to greater bird abundance, with undisturbed zones encouraging larger congregations and longer stays. This observation provides valuable insights for balancing conservation priorities with tourism management in ecologically sensitive areas.
The census results highlight both the resilience of Gujarat's wetland ecosystems and the dynamic nature of migratory patterns. As conservation efforts continue to evolve, the data will inform future strategies for protecting these vital habitats and their avian visitors.
