Abstract

Filaments of horse-hair fungus (genus Marasmius) were preliminarily found in nests of 98 bird species from 27 families in the tropics and nearctis. Marasmius filaments are used for nest structure but are also known to contain antibiotic and anti-carcinogenic properties. At least locally, birds gather these filaments selectively. We therefore hypothesise a probable selective advantage for birds using Marasmius in their nests.
