This is very cool and lends even more evidence to what has been more or less clear in the avian neuro community. This genetic/dev evidence in a similar brain region supports previous work by Karten (mentioned in the article) and others on bird auditory "cortex".
The mantra is "nuclear" or "regional" organization in birds rather than layers in mammals, but the anatomy [0, Fig 4] and electrophysiology [1] abstract this out in similar patterns.

Marsupials too! Sort of.
Generally, marsupials are mostly close to other mammals in brain structure, but they do have a fair bit less layers and some nuclear structures.
Comparative neuroanatomy in vertebrates is, like, super interesting (to me at least). It really goes to show off evolution and how her pressure is really towards more babies - however that needs to be accomplished.
