A bird does not "actively" adapt its body. That is not how evolution works, a hummingbird's body is adapted to its environment over many generations by the process of natural selection (survival of the fittest).

Ryan Stinson states "the average weight of a hummingbird is somewhere between 2 and 20 grams."

Move up on your weight.
A Hummingbird drinks nectar, not pollen. As for how much nectar one drinks per day, I believe it is equal to (or more than) the Hummingbird's body weight.
The body adapts to the presence of the stressor.
A hummingbird's heart is relatively large compared to its body size, making up about 2.5-2.7% of its total body weight. This is because the high metabolic rate and rapid wing beats of a hummingbird require a lot of energy and oxygen to sustain flight.
Depending on where you are, there's a good chance you observed a hummingbird moth. It looks a lot like a large bee but flies and looks like a small hummingird with a bee body. Google hummingbird moth for pictures.
A hummingbird is an endothermic animal, meaning it can regulate its body temperature internally by generating metabolic heat. This allows hummingbirds to maintain a high body temperature even in colder environments.
Every second the body of an animal adapts to it's surroundings.
They have a Streamline shape, wings ,feathers and hollow bones.
Maybe something like a butterfly
