Create a hyper-realistic digital illustration of a close-up portrait of a vibrant parrot perched on a branch. The parrot's feathers should exhibit a stunning array of colors, including bright reds, deep blues, and sunny yellows, with intricate patterns that showcase the texture of its plumage. Utilize a macro lens effect to capture the fine details of the feathers, ensuring the parrot's expressive eyes are the focal point of the composition. The background should be a lush green rainforest, softly blurred to create depth and allow the parrot to stand out. Simulate natural sunlight to cast soft shadows that enhance the depth of the feathers and highlight the parrot's eyes. The image should be rendered in 4K resolution with a 16:9 aspect ratio, making it ideal for a desktop wallpaper.
