Cardinal eggs typically are small, about 1 inch long and less than an inch wide, oval-shaped. Their color varies but is usually light, ranging from whitish or mild gray to a faint blue or greenish hue. The eggs often have speckles or spots in brown, gray, pink, or sometimes purple, which serve as camouflage. These speckles are dispersed over the egg surface, making the eggs less conspicuous in their open-cup nests. Overall, cardinal eggs have a delicate, speckled look with soft pastel shades blending into natural surroundings.
