Dendrobatidae (dart-poison frogs) exhibit some of the most complex spatial behaviors among amphibians, such as territoriality and tadpole transport from terrestrial clutches to widely distributed deposition sites. In species that exhibit long-term territoriality, high homing performance after tadpole transport can be assumed, but experimental evidence is lacking, and the underlying orientation mechanisms are unknown. We conducted a field translocation experiment to test whether male Allobates femoralis, a dendrobatid frog with paternal extra-territorial tadpole transport, are capable of homing after experimental removal, as well as to quantify homing success and speed. Translocated individuals showed a very high homing success for distances up to 200 m and successfully returned from up to 400 m. We discuss the potential orientation mechanisms involved and selective forces that could have shaped this strong homing ability.

归巢蛙：陆地树蛙的高归巢性能Allobates femoralis（Dendrobatidae）

Dendrobatidae（箭毒蛙）在两栖动物中表现出一些最复杂的空间行为，例如领土性和从陆地离合器到广泛分布的沉积地点的蝌蚪运输。在表现出长期领土性的物种中，可以假设蝌蚪运输后的高归巢性能，但缺乏实验证据，并且潜在的定向机制未知。我们进行了一项田间易位实验，以测试雄性 Allobates femoralis（一种具有父系域外蝌蚪运输的树突蛙）是否能够在实验移除后归巢，并量化归巢成功率和速度。易位个体在高达 200 m 的距离上表现出非常高的归巢成功率，并成功地从高达 400 m 的距离返回。
