Create an ethereal, glowing bird with luminescent feathers in shades of blue

Create an ethereal, glowing bird with luminescent feathers in shades of blue, purple, and white, perched on a delicate, swirling branch. The bird should have an otherworldly glow, with light emanating from its body and wings, giving it a magical, celestial appearance. Surround the bird with a dreamy, cosmic background featuring vibrant colors such as deep blues, purples, and oranges. Incorporate swirling, wispy clouds and light trails that give a sense of motion and fantasy. Add subtle sparkles and glowing orbs to enhance the mystical atmosphere. The overall composition should be whimsical, enchanting, and filled with a sense of wonder and tranquility.
