非人类动物的长期记忆和回忆信息的能力主要是为了特殊的需要而进化的，比如学习物种典型的发声和储存食物1-6。 然而，在非人类动物中，个体社会伙伴的长期记忆以前没有被证明。 识别个体的能力对复杂社会互动的进化具有重要影响7-11，并为动物社会中更复杂的认知形式提供了基础12，13。 对于领地鸣禽来说，社会伙伴的识别已经被记录在案，它们可以区分不同邻居的歌曲14-16以及陌生人和邻居的歌曲17。 在这里，我表明，男性冠莺（Wilsonia citrina，Parulinae）不仅承认他们的邻居单独的歌曲在繁殖季节，但也保留了记忆的邻居的歌曲后，8个月的时间，在此期间，他们停止唱歌，迁移到中美洲之前，他们返回前繁殖区。
Capabilities for long-term memory and recall of information have evolved in non-human animals primarily for special requirements such as for learning species-typical vocalizations and caching food 1-6. Long-term memory of individual social partners has, however, not been demonstrated previously for non-human animals. The ability to recognize individuals has important consequences for the evolution of intricate social interactions 7-11 and provides a basis for more sophisticated forms of cognition in animal societies 12,13. Recognition of social partners has been documented for territorial songbirds, which discriminate between songs of different neighbours 14-16 as well as between the songs of strangers and neighbours 17. Here I show that male hooded warblers (Wilsonia citrina, Parulinae) not only recognize their neighbours individually by song during the breeding season, but also retain the memory of neighbours' songs after an 8-month period during which they cease singing and migrate to Central America before they return to former breeding territories.
