Have you ever wondered why female hummingbirds are larger then the males? This is the kind of question my mother would have wanted answered, so if you have ever wondered the answer to this question as well then this post is just for you. Hope you enjoy what you read here.
Female hummingbirds are solely responsible for the care and rearing of the young. Therefore, the females need to be a tiny bit bigger to be able to produce eggs, to afford to share their body heat with the eggs while incubating, and to be able to share their food when feeding nestlings. It may surprise you, as it did me, to learn that male hummingbirds are the tiniest warm-blooded animals on the planet.
