This video takes a look at our hummingbird friends and caregivers in Brazil.
Hummingbirds are hyperactive animals, they can move their wings over fifty times per second. They can do that because they have a strong heart. Their hearts are 20% of its weight.
They love the nectar, and may eat up to sixteen hours without stopping. For perspective this is like if we eat 50 kilos (110 pounds) of bread.
