Watching a hummingbird fly around a bush checking out each flower, you might think it is following a random path, but it isn’t. Studies show hummingbirds remember every flower they visit.
Can you imagine that? This firebush in our yard has a thousand flowers on it.
The hummingbird knows this bush and every other bush in the neighborhood! It doesn’t waste time going back to a flower it has already visited and it knows how long to wait for the plant to replenish the pollen and nectar.
How do they do it? Brains. Size matters. Now you may not think much of the size of a hummingbird brain, it’s smaller than a pea, but the brain of a hummingbird makes up 4% of its bodyweight. We humans? A measly 2%. So the next time somebody calls you a birdbrain, check to see if they mean hummingbird.
