How do nightjars like the chuck-will's-widow use camouflage to protect their nests?

The nightjar, particularly the chuck-will's-widow, employs effective camouflage to protect its nest and young. Its eggs and chicks mimic the colors and textures of their surroundings, allowing them to blend seamlessly with the leaf litter and ground cover in their habitat.^[1] This form of disguise not only deters potential predators but also conceals them during vulnerable stages of development. Consequently, when approached, they often remain motionless, significantly increasing their chances of survival.^[1]
