The fiery-throated hummingbird (Panterpe insignis).

Both males and females look alike. Immature birds have rufous-colored fringes to their head feathers.

Hummingbirds are named after the humming sound made by the beat of their wings. Their wings make up to 100 beats per second, moving so rapidly that the naked eye cannot detect them. They are the only birds that can generate power on both the forward and backward wing strokes, which makes backward fly possible.
