The ophthalmic nerve in the upper beak was labelled with cholera toxin B-chain, and iron was identified using the Prussian Blue reaction. Iron deposits were found in the caudal part of the beak, and some were concentrated in cells that clustered in encapsulated structures densely innervated by ophthalmic nerve fibres. Such structures could form the anatomical basis of a type of mechanoreceptor that transmits magnetic sense information to the brain.
对上喙中的眼神经用霍乱毒素B链进行标记，并用普鲁士蓝反应鉴定铁。在喙的尾部发现了铁沉积物，其中一些集中在由眼神经纤维密集支配的被膜结构中聚集的细胞内。这种结构可能构成一种将磁感觉信息传递到大脑的机械感受器的解剖学基础。
