Context: Hawksbill sea turtles (Eretmochelys imbricata) are conservation-dependent species in many areas of the world. A key component to ensuring successful conservation initiatives for the species is understanding their distribution and habitat use, in particular, knowing the nesting sites, migration routes and foraging areas for each genetic stock, and how these might overlap with threats.

Aims: Investigate the post-nesting movements of hawksbill sea turtles nesting in the Torres Strait, including migration movements and foraging ground size and distribution.

Methods: Nine nesting hawksbill turtles of the north-eastern Australian genetic stock were satellite-tagged between the 2010 and 2019 nesting seasons for 182 ± 143 days (mean ± s.d.).

Key results: Three turtles continued to nest on adjacent islands before commencing their post-nesting migrations. From the nine tracked turtles, the following three migration movement strategies were identified: (1) direct migration between the nesting beach and foraging ground, (2) non-direct movements with a period of meandering, and (3) establishment of two foraging areas separated by direct movement pathways. Foraging grounds were distributed across the Torres Strait and north-eastern Australia and varied in size between 0.54 km² and 3.31 km² (95% UD). None of the turtles migrated outside of Australian waters.

Conclusions: The localisation of these movements and habitats within Australian waters provides a unique conservation opportunity, whereby protection efforts involve multiple life stages and potentially preserve turtles from multiple genetic stocks. The variety of inter-nesting, migration and home range strategies used by the tracked turtles in the present study highlight the broad scope of hawksbill movements.

Implications: Our findings are useful for the implementation of future marine conservation areas and shed light into the nesting, migratory and foraging behaviours of hawkbills from this genetic stock. An understanding of the movement tracks and habitats used by a genetic pool is essential for well grounded implementation of conservation areas and management regulations.

背景：玳瑁海龟（Eretmochelys玳瑁）是在世界许多地区依赖保育。确保成功实施该物种保护措施的关键因素是了解其分布和栖息地使用情况，尤其是要了解每种遗传种群的筑巢地点，迁徙路线和觅食区域，以及它们如何与威胁重叠。

目的：调查在托雷斯海峡筑巢的b海龟的筑巢后运动，包括迁徙运动和觅食地面的大小和分布。

方法：在2010年至2019年的筑巢季节之间，对澳大利亚东北部遗传种群的9只筑巢进行了卫星标记，为期182±143天（平均±sd）。

主要结果：三只海龟在开始筑巢后的迁徙之前仍继续在邻近的岛屿上筑巢。从九只被追踪的海龟中，确定了以下三种迁徙运动策略：（1）筑巢海滩和觅食场之间的直接迁徙；（2）蜿蜒一段时期的非直接运动；（3）建立两个觅食区由直接运动路径隔开。觅食场分布在托雷斯海峡和澳大利亚东北部，大小在0.54 km ²和3.31 km ²（95％UD）之间变化。没有一只乌龟迁移到澳大利亚水域以外。

结论：这些运动和栖息地在澳大利亚水域内的定位提供了独特的保护机会，由此保护工作涉及多个生命阶段，并可能从多种遗传资源中保护海龟。在本研究中，被追踪的海龟使用的各种相互嵌套，迁徙和迁徙策略，突显了b运动的广泛范围。

启示：我们的发现对于实施未来的海洋保护区很有用，并有助于了解这种遗传种群中的鹰嘴鸟的筑巢，迁徙和觅食行为。对遗传资源库所使用的运动轨迹和栖息地的了解，对于有充分依据的保护区和管理规定的实施至关重要。
