Abstract
Two different kinds of collections have been used to anticipate influenza pandemics: viral strains and bird specimens. These collections have been organized in museums and data banks to fill the gaps when specimens were decaying or when viral strains were missing. This article asks how collecting practices changed when such collections integrated specimens from China, considered a reservoir of influenza viruses and bird species, following a recurrent critical trope that Chinese specimens were missing. The article shows that techniques for hunting viruses and birds were used to accumulate information so as to mitigate the global threat of species extinction. It suggests that in sentinel territories, museums transform samples and specimens into signs and images of future catastrophic events.
