Locating Lice as They Hitch-Hike With Birds for Life



ScienceDaily (May 14, 2012) — Although chewing lice spend their entire lives as parasites on birds, it is difficult to predict patterns of lice distribution, new research from the University of Gothenburg, Sweden, reveals.

Researcher Daniel Gustafsson has studied chewing lice on sandpipers around the world and investigated how host birds' migration patterns affect louse distribution and relationships.

With no wings and very small eyes, chewing lice are, by and large, helpless away from their host.

Daniel Gustafsson has studied species of chewing lice that live on the birds' wings and compared them with species that live on their body feathers.

"Given that chewing lice are almost totally dependent on direct contact between two birds to spread, lice that sit on birds' wings should find it easier to use occasional contact between two hosts to spread than those that sit closer to birds' bodies," Daniel Gustafsson says.
