Ahmedabad, Aug. 19 -- The critically endangered Lesser Florican, the world's smallest bustard, uses a high-density migration corridor of nearly 60,000 sq km across western and central India while remaining strongly dependent on grasslands even when it moves through croplands and other open habitats, a new satellite-tracking study has found.

The study, published in Frontiers in Conservation Science on Wednesday, mapped a broad migration flyway spanning about 206,000 sq km across India for the endangered Lesser Florican (Sypheotides indicus).

"By linking fine-scale movement behaviour with landscape-scale patterns of land-use change and population decline, this study reinforces a central conclusion: the Lesser florican remains fundamentall...
