Mallard duck eggs are typically a pale blue or greenish color. These eggs are often described as having a soft, delicate hue, which can sometimes appear almost white depending on the lighting and environment.
The coloration of the eggs serves a purpose in nature; it helps camouflage the eggs in their natural nesting environment, which is usually among grasses and reeds near water bodies. This camouflage is crucial for protecting the eggs from potential predators.
Interestingly, the color can vary somewhat between individual hens, and some may lay eggs that are slightly darker or have more of a tint. However, if you come across eggs that resemble this pale blue or green shade, they are likely from a mallard duck.
