The Corbett Foundation’s Kedar Gore, a wildlife conservationist, told mid-day that two lesser floricans migrated from the breeding area in 2022. According to the study, the first signs of migration were observed between October 29 and 30, 2022, when one bird — named LFM9 — travelled approximately 25 km southwards from Ratanpur village, Vallabhipur taluka to Golrama village, Umrala taluka of Bhavnagar district, Gujarat.

LFM9 continued its southward journey in shorter distance segments of approximately 20 km until November 11, using stopovers in 16 villages distributed in two districts of Gujarat and 15 villages located in three districts of Maharashtra. “LFM9 crossed the Gulf of Cambay (also known as Gulf of Khambhat) between November 18 and 19, flying approximately 125 km in one attempt and settling in croplands near Gadaria village, Valsad taluka, Valsad district. Then, covering a distance of approximately 100 km in a single day, it crossed Gujarat between November 19 and 20 and entered Maharashtra on November 21, where it settled in croplands in proximity to an irrigation canal in Gargaon village, Wada taluka, Palghar district. By December 2, it had travelled approximately 300 km from the previous location in one day and reached Man taluka in the Satara district Of Maharashtra,” the study stated.

The study points out that during its migration, the other bird — named LFM10 — exhibited nomadic behaviour between November 15 and 26. “It then crossed the Gulf of Cambay on November 26-27 by flying approximately 95 km and entered Kalwan taluka, Nashik district after covering a distance of around 260 km from Gujarat in a single day. LFM10 used a total of 12 stopovers in four districts of Gujarat and 12 in three districts of Maharashtra during its migration,” the study mentions. LFM9 and LFM10 flew at elevations ranging from 176 m to 313 m and covered distances of 4.24 km to 116 km per day. In a month, the maximum distance covered by LFM9 was 2,029 km and by LFM10 was 3,505 km. The distances covered depended on the type of habitats they flew over and the availability of food.

Proactive protection

Welcoming the study, Gore said there is a need to satellite tag more birds and understand their lives to counter the damages done by human activity. “The lesser florican is endemic to India and has perhaps just 600 individuals surviving today. The radio telemetry of this ‘mystery’ bird provides important information about its migration routes and habitat choices. It is important to continue such research and deploy satellite tags on more birds to acquire in-depth information that will help devise long-term conservation strategies. There is not much time left as the birds are facing similar threats of habitat loss, anthropogenic disturbances and power line collisions, among others, as faced by the Great Indian Bustard. We need to learn from past mistakes and not let the lesser florican reach the same precarious situation as the Great Indian Bustard. Timely action in the interest of these species is a must.”
