PCR-based method for sex identification of Eastern sarus crane (Grus antigone sharpii): implications for reintroduction programs in Thailand.

Due to human activity and a reduction in the size and quality of wetland habitats, populations of the Eastern sarus crane (Grus antigone sharpii) have declined dramatically across their range in Southeast Asia. Conservation efforts in Thailand have focused on reintroduction of the founders harboring the highest genetic diversity. One of the most important requirements to ensure the persistence of the reintroduced populations is a balanced sex ratio.
