Anybody have a good source on how bird cognition works? (They have virtually no cortex, but corvids and parrots can rival primates in the complexity of tasks they learn.) Do birds have some equivalent of the hierarchical/filter-bank image processing structures mammals do?

This paper goes specifically into comparative parrot neuro-anatomy. It suggests that the bird pallium is important, (convergently?) cognate to the human (prefrontal?) cortex, with (convergent?) higher bandwidth to the (conserved?) cerebellum.https://www.nature.com/articles/s41598-018-28301-4 …
