Migratory Songbirds as Potential Ectozoochorous Protist Dispersal Vectors. [PDF]
Ecol EvolWe demonstrate that migratory songbirds carry diatoms (Bacillariophyta) in their plumage, revealing an unexpected avian–algal association. All seven bird specimens we examined contained diatoms—224 frustules representing 25 genera and 9 orders, primarily freshwater, benthic pennates—some retaining chloroplasts prior to digestion and mounting (implying ...
