| Archilochus colubris (Ruby-throated Hummingbird) invariably decorate the exterior surface of their nests with living foliose lichen. Lichen fragments may be carried considerable distances, but it is unknown whether transported thalli survive at nest sites. Here we report the multi-year persistence of a transported thallus of Myelochroa aurulenta (Powdery Axil-bristle Lichen) at a hummingbird nest site. Our observation suggests that hummingbirds may be important dispersal agents for foliose lichens. | |
