In Children of Memory, by Adrian Tchaikovsky, the corvid mind is a plot device, particularly their approach to recognition of novelty, organization into memories/archives, and problem solving by combining those.
The book is a sequel, of sorts, to Children of Time and Children of Ruin, and they should be read in sequence.
All three books grapple with "what is intelligence?" by using approximately familiar devices to land definitions that might otherwise be too alien.
