The avian vocal system is a good model for exploring the molecular basis of neural circuit evolution related to behavioral diversity. Previously, we conducted a comparative gene expression analysis among two different families of vocal learner, the Bengalese finch (Lonchura striata var. domestica), a songbird, and the budgerigar (Melopsittacus undulatus), a parrot; and a non-learner, the quail (Coturnix coturnix), to identify various axon guidance molecules such as cadherin and neuropilin-1 as vocal control area-related genes. Here, we continue with this study and examine the expression of neuropilin and related genes in these species in more detail. We found that neuropilin-1 and its coreceptor, plexin-A4, were expressed in several vocal control areas in both Bengalese finch and budgerigar brains. In addition, semaphorin-3A, the ligand of neuropilin-1, expression was not detected in vocal control areas in both species. Furthermore, there was some similar gene expression in the quail brain. These results suggest the possibility that a change in the expression of a combination of semaphorin/neuropilin/plexin was involved in the acquisition of vocal learning ability during evolution.
