ndian Grey Hornbill in Gir Forest
The Indian Grey Hornbill (Ocyceros birostris) has achieved a major conservation milestone with four consecutive years of successful breeding in Gujarat’s Gir Forest after its reintroduction in 2021. The species had disappeared from the region more than six decades ago, making its successful return a remarkable example of wildlife restoration and habitat conservation.
A study published in the journal Birds confirms that the reintroduced hornbill population has successfully adapted to its new habitat, established breeding territories, and begun natural reproduction. This achievement highlights the effectiveness of the Gujarat Forest Department’s conservation programme and underscores the importance of scientific wildlife management.
For UPSC aspirants, this topic is important under Environment & Ecology, Biodiversity, Wildlife Conservation, Protected Areas, and Species Conservation.
