Abstract
The movements of 17 eastern sarus cranes Grus antigone sharpii in Cambodia and Vietnam were tracked during both wet and dry seasons in 1998−2002 and 2015−2017, revealing previously unknown but important sites. Crane breeding territories were located in Cambodia’s northern dry deciduous dipterocarp forests, with territories of cranes captured in the Tonle Sap basin located further west and more likely to fall within protected areas than those captured in the Mekong Delta. During the non-breeding (dry) season, cranes returned to sites in which they had originally been captured. Most cranes initially used a different part of the same floodplain in the early stages of the dry season, but cranes from the Mekong Delta that nested west of the Mekong River would initially stop in the eastern Tonle Sap floodplains before continuing to the Mekong Delta floodplains. Protected area coverage of key dry season habitat within the Tonle Sap basin was lower than in the Mekong Delta. Out of 5 juveniles tracked in 2015/2016, 1 disappeared, 1 died and 1 was injured; 1 adult also disappeared. All mortality and disappearances occurred during the wet season and at least 1 mo after capture. Persistence of the eastern sarus crane will require improvement of protected area coverage of both breeding areas and previously unknown but important sites used during the dry season.

Bibliographical note
Funding Information:The purchase of 10 GSM transmitters from e-obs was made possible through a grant from the National Geographic Conservation Trust. Yamashina Institute for Ornithology purchased 7 Argos PTT tags for deployment in 1998 and 2001. Kranichschutz Deutschland kindly donated coloured leg bands to the project. The Charles Darwin University enabled J.B. to help coordinate crane catching in 2015 and helped cover fieldwork costs, as did the Critical Ecosystem Partnership Fund, administered for the Indo-Burma hotspot through the IUCN-Asia Regional Office. The Critical Ecosystem Partnership Fund is a joint initiative of l’Agence Française de Développement, Conservation International, the European Union, the Global Environment Facility, the Government of Japan, the MacArthur Foundation and the World Bank. Our animal capture, handling and marking techniques were approved by the Animal Care and Use Committee at the International Crane Foundation (permit 007) and the Charles Darwin University Animal Ethics Committee (permit A13021). Permission to conduct this study was received from the relevant authorities in Cambodia and Vietnam. The Wildlife Conservation Society, Wildfowl & Wetlands Trust and BirdLife International facilitated the research project in 2015, the International Crane Foundation and Yamashina Institute for Ornithology in 1998 and 2001. Key people from these agencies and organi zations were Bou Vorsak, Jonathan Eames, Sara Gavney Moore, Andy Gossens, Andy Graham, Hong Chamnan, Simon Mahood and Kunikazu Momose. Kit Sokny assisted in the organization and implementation of all fieldwork activities. Duy Le, Touch Kea, Reng, Kin, Hom, Coin, Honda, Kna and Sai assisted with capture, tagging and release of cranes. The Angkor Centre for Conservation of Biodiversity and the Phnom Tamao Wildlife Rescue Center were responsible for the recovery and release of sick, injured or confiscated cranes. Key people here were Christel Griffioen, Nick Marx, Michael Meyerhoff and Phok Samphos
