bird-brained
Lacking mental capacity
Bird-brained means stupid or scatterbrained, from the notion that birds have small brains and limited intelligence.
The insult suggests someone flighty and incapable of sustained thought: What bird-brained idea made you think that would work?
Despite the metaphor, many bird species demonstrate remarkable cognitive abilities.
