Orchids produce remarkably small seeds lacking endosperm, which are considered to be predominantly wind-dispersed. Here, we report avian seed dispersal in a mycoheterotrophic orchid Cyrtosia septentrionalis, which occurs under closed canopies where wind is less dependable. Because some orchids occupy similar habitats and have fleshy fruits, shifts in seed dispersal strategy may be a previously unnoticed mechanism promoting the orchid's evolutionary success.
