They have a brain the size that is proportional to their small bodies.
as smart as some humans
Some examples of big animals with relatively small brains are elephants, blue whales, and sperm whales. These animals have massive bodies, but their brain size in proportion to their body size is smaller compared to other animals.
The VAST majority of living humans do indeed have working brains, although that fact is not always apparent by their actions.
Yes, they have both a brain and a heart, But their brain is very small and their blood is not red like Humans.
the word 'small' is qualitative and therefore can not be answered effectively. Birds in general do have small brains.
Monkeys Brains are about 400g were as human brains are about 1400g and are 15cm, monkeys brains are only about 8cm long!

No, Humans brains are much more developed. YOU SHOULD KNOW THAT!
All things are relative. Compared to an earthworm, turtles have big brains. Compared to a dog, turtles have small brains.
The amount of cerebral cortex is larger. a cat has small amounts. Humans have much more and is a little more than a ape. Animals have the same brain structure as humans, it is just managed differently. (the cerebral cortex covers the entirety of the brain)
Humans have one brain.
