长距离迁徙的滨鸟的保护工作十分复杂，因为这些物种的栖息地遍布各大洲和半球，这使得确定关键栖息地和年度周期中的潜在瓶颈尤为困难。在西欧繁殖的黑尾Godwits，Limosa limosa limosa，在过去的几十年里急剧下降。尽管为查明这一下降的根本原因作出了重大努力，但仍有许多问题不清楚。为了更好地了解迁徙的时间，使用中途停留和nonbreeding网站，以及繁殖成功对这些参数的潜在影响，我们附加了15个Argos卫星发射器和10个地理定位跟踪设备，成年godwits接近完成孵化在西南部弗里斯兰，荷兰在2009年春天的繁殖地点。我们成功地追踪了16只成年斗鱼的整个南迁过程和另外两只的部分南迁过程，发现了三种南迁模式和四个使用区域。大多数的白颈长尾雉离开它们的繁殖地，直接向南飞到地中海的中途停留地--例如西班牙、葡萄牙和摩洛哥--然后飞到西非的非繁殖地。其他个体在地中海度过了整个非繁殖季节。第三种模式包括一些个体从荷兰的繁殖地不停地飞到西非的非繁殖地。这项研究的跟踪数据将立即有助于保护工作，重点是保护godwits在向南迁移期间使用的分散的网站网络。
Conservation of long-distance migratory shorebirds is complex because these species use habitats spread across continents and hemispheres, making identification of critical habitats and potential bottlenecks in the annual cycle especially difficult. The population of Black-tailed Godwits that breeds in Western Europe, Limosa limosa limosa, has declined precipitously over the past few decades. Despite significant efforts to identify the root causes of this decline, much remains unclear. To better understand the migratory timing, use of stopover and nonbreeding sites, and the potential impact of breeding success on these parameters, we attached 15 Argos satellite transmitters and 10 geolocation tracking devices to adult godwits nearing completion of incubation at breeding sites in southwest Friesland, The Netherlands during the spring of 2009. We successfully tracked 16 adult godwits for their entire southward migration and two others for part of it. Three migration patterns and four regions of use were apparent. Most godwits left their breeding sites and proceeded south directly to stopover sites in the Mediterranean — e.g. Spain, Portugal, and Morocco — before flying on to non-breeding sites in West Africa. Other individuals spent the entire nonbreeding season in the Mediterranean. A third pattern included a few individuals that flew nonstop from their Dutch breeding sites to nonbreeding sites in West Africa. Tracking data from this study will be immediately useful for conservation efforts focused on preserving the dispersed network of sites used by godwits during their southward migration.
