在研究1中，将滨燕（R. riparia）雏鸟与其他同龄雏鸟进行交换。父母接受雏鸟在15天或更小的时候被转移到他们的巢穴；排异反应在16-17天开始发生。在研究2中，记录了雏鸟在洞穴中的发声。雏鸟在15-17日龄时发出的不成熟的乞求叫声被标志性的叫声所取代。一项声学分析表明，这些叫声是独特的。研究3是一个回放实验，旨在测试雏鸟的标志性叫声是否足以引起父母的认可。父母们更倾向于用扬声器播放自己的雏鸟的叫声，而不是同时播放外星雏鸟的叫声。结果表明，父母的识别是基于雏鸟的特征呼叫，识别的发展取决于呼叫的发展。
In study 1, bank swallow (R. riparia) chicks were exchanged with like-aged chicks from other broods. Parents accepted chicks that were transferred into their nests at age 15 days or younger; rejection began to occur at 16-17 days. In study 2, chicks'' vocalizations were recorded in the burrow. An immature begging call given by young chicks is replaced by a signature call at 15-17 days of age. An acoustic analysis suggested that these calls are individually distinctive. Study 3 was a playback experiment designed to test whether the chicks'' signature calls are a sufficient cue for parental recognition. Parents would approach a speaker broadcasting the calls of their chicks in preference to one simultaneously broadcasting the calls of alien chicks. The pattern of results suggests that parental recognition is based on the chicks'' signature calls and that development of recognition is dependent on the development of the call.
