Depict a heartwarming birthday scene set outdoors, featuring a clear and vibrant blue sky as a backdrop. The focal point is a group of adorable birds endowed with oversized eyes and clad in miniature tennis outfits. They are cheerfully perched on a net which stretches across a cake, interestingly designed to mirror a tennis court with its distinctive clay red hue. Suspended in the air above them is a banner with the text 'Happy Birthday!' rendered in jubilant, bold letters.
