Show Notes
The treeswifts of India, Southeast Asia, New Guinea, and beyond make their nests out of bits of plants and feathers and hold it all together with some very sticky saliva. A treeswift’s whole nest is but a tiny cup — just large enough to hold a single egg — stuck to a bare upright branch. The adult on the nest appears simply to be perching, not sitting on a nest. Ingenious!
