信鸽（Columba livia）对熟悉区域的识别至少部分依赖于视觉线索。鸟类允许5分钟的预览周围的景观之前，释放回家的速度比那些拒绝访问这些线索，这表明识别视觉介导。我们进一步研究了这一现象，询问如何通过先前的经验与一个网站产生的记忆是用于识别。我们为一组信鸽提供了训练经验，让它们在放飞前通过一个不透明的放飞箱的一个透明的垂直面观察大约140度的景观5分钟。训练预览总是在发布现场的一致位置和方向上进行。随后的测试版本被用来确定后续的网站识别是否需要从这个已经熟悉的角度和距离预览，或者该技能是否可以扩展到新的，不重叠的景观侧视图。结果表明，归航性能更好的演示后的观点概括，看到在培训比后，显示一个新的替代观点。猪笼草可能已经使用了一个模板的安排熟悉的地标周围的释放网站作为线索的识别。然而，效果消失后，反复训练，这表明，重复释放从一个网站可能允许更广泛的视觉调查和记忆的详细功能的景观或提取特定网站的一般功能，帮助识别，即使是一个新的观点。(C)2003年，动物行为研究协会。由爱思唯尔科技有限公司出版。保留所有权利。
The recognition of familiar areas by homing pigeons, Columba livia, is now known to depend at least in part on visual cues. Birds allowed a 5-min preview of the surrounding landscape prior to release home faster than those denied access to such cues, suggesting that recognition is visually mediated. We examined this phenomenon further by asking how memory generated through prior experience with a site is used in recognition. We provided a group of homing pigeons with training experience in which they viewed, through a single transparent vertical face of an otherwise opaque release box, an approximately 140degrees segment of the landscape for 5 min before release. Training previews were always given from consistent locations and orientations within a release site. Test releases that followed were used to ascertain whether subsequent site recognition necessitated previewing from this already familiar angle and distance, or whether the skill could be extended to novel, nonoverlapping lateral views of the landscape. The results suggested that homing performance was better after presentation of the view recapitulating that seen during training than after showing a novel alternative view. Pigeons may have been using a template of the arrangement of familiar landmarks around the release site as the cue for recognition. The effect, however, disappeared after repeated training, suggesting that repeated release from a site may allow for more extensive visual survey and the memorization of detailed features of the landscape or the extraction of site-specific general features that aid recognition even when a novel view is presented.
