许多种类的鸟类和蝙蝠在繁殖地和越冬地之间进行季节性迁徙。在途中，移徙者在飞行期间和停留时间之间交替，停留时间是个人休息和为随后的飞行加油的时间和空间。我们通过使用一组带有多个天线的自动遥测接收器来跟踪在20×40 km的地理区域内的个体的日常位置，评估了移民在中途停留期间所做的运动的空间尺度。我们跟踪了7个迁徙脊椎动物物种（5雀形目，猫头鹰和蝙蝠）的322个人在春季和秋季迁徙中途停留和邻近的一个大湖半岛的运动。我们的研究结果表明，许多人离开他们的捕获现场搬迁在同一景观在中途停留期间的某个时候，移动多达30公里远，从他们最初的捕获现场。我们发现，许多明显的夜间离开中途停留的网站是不是在最严格的意义上恢复迁移，而是搬迁，代表在更广泛的空间尺度上继续中途停留。
Many species of birds and bats undertake seasonal migrations between breeding and over-wintering sites. En-route, migrants alternate periods of flight with time spent at stopover – the time and space where individuals rest and refuel for subsequent flights. We assessed the spatial scale of movements made by migrants during stopover by using an array of automated telemetry receivers with multiple antennae to track the daily location of individuals over a geographic area ∼20×40 km. We tracked the movements of 322 individuals of seven migratory vertebrate species (5 passerines, 1 owl and 1 bat) during spring and fall migratory stopover on and adjacent to a large lake peninsula. Our results show that many individuals leaving their capture site relocate within the same landscape at some point during stopover, moving as much as 30 km distant from their site of initial capture. We show that many apparent nocturnal departures from stopover sites are not a resumption of migration in the strictest sense, but are instead relocations that represent continued stopover at a broader spatial scale.
