Learning is also one reason many songbirds have regional dialects. Morphology OTOH is determined genetically so it is intermediate because the hybrid have genes from 2 different species which have different morphologies. So, the hybrid would learn either one song or the other, or perhaps even both songs, but not an intermediate song...
