Forests are crawling with predators, and young chicks make for an easy meal, so many birds, such as this Dusky Broadbill make sure their nests are hard to raid. Using moss, lichens, and other plant matter these birds build what’s referred to as a pendulous cup nest, dangling from a thin branch and resembling tangled, rotting vegetation. Some broadbills even decorate the outside of the nest with cobwebs, creating an even more convincing disguise.
