40 gramsCompared to us mammals, birds have relatively small brains, reaching a maximum of over 40 grams in the Emperor Penguin, a very large, flightless species. Brain size is an important indicator of intelligence, but the ratio of brain to body size is equally telling.birdfact.com/anatomy-and-physiology/nervous-system/avian-brain-structure-an…- See moreSee all on Wikipedia
Avian brain - Wikipedia
The size and structure of the avian brain enables prominent behaviours of birds such as flight and vocalization. Dedicated structures and pathways integrate the auditory and visual senses, strong in most species of birds, as well as the typically weaker olfactory and tactile senses. See more

Wikipedia text under CC-BY-SA license Bird intelligence - Wikipedia
Bird intelligence has been studied through several attributes and abilities. Many of these studies have been on birds such as quail, domestic fowl, and pigeons kept under captive conditions. It has, however, been noted that field studies have been limited, unlike those of the apes. Birds in the crow family (corvids) as well as parrots (psittacines) have been shown to live socially, have long devel…
