Question of the week:
How smart is a hummingbird?
A. Real smart, as it turns out. Their hippocampus – the area of the brain responsible for learning and memory – is up to five times bigger than that in songbirds, seabirds and woodpeckers.
A hummingbird can remember where every flower is located in their territory and how long it takes to refill with nectar. Not bad for a bird that has a pea-sized brain. So maybe size does not matter after all.
