Where do most true nightjars rest during the day?

Most true nightjars (subfamily Caprimulginae) typically roost on the ground, rocks, or fallen trunks during the day. While many are ground-dwellers, some species prefer to rest on horizontal tree branches, where they usually perch lengthwise along the branch to maintain their camouflage.12

Their daytime resting habits are closely tied to their protective coloration, which allows them to blend into their surroundings; for instance, woodland-dwelling species often feature patterns resembling fallen leaves and detritus on the forest floor, while those in gravelly areas may appear similar to scattered stones. Although they are primarily ground roosters, some individuals may occasionally utilize higher, slender branches or vines as singing or foraging posts, where they may sit crosswise.32
