Create an image of a yellow hummingbird in mid-flight against a purple background. The bird should radiate with vibrant yellow hues, offering a striking contrast to the darkness. Its feathers should catch the light, showing off a variety of golden shades that bring out the texture and delicate nature of its plumage. The wings should be depicted in a rapid motion, a blur that conveys the hummingbird's swift movement, while the body remains in sharp focus. The bird's poised beak and bright eyes should be prominent, capturing the essence of its lively spirit.
