Saint Louis Zoo

They are attempting a proactive approach with their research

Studies Involve:Safe capture and handling of birds

Blood samples are taken

Blood smears are made

Whole blood samples stored for preservation

Birds are given physical examinations

Birds are dusted for ectoparasites

Since 2003More than 7,000 individuals examined

Tested 3 introduced species for pathogens

Established the disease vector mosquito

Characterized strains of avian poxvirus

Established baseline health studies

Discovered the first Plasmodium parasite

Discovered a new microfilarid nematode

Culex qinquefasciatus

Microfilarid nematode

Collaborator Dr. Herman Vargas

Three Categories of Pathogens

1. Those that appear to have colonized with their avian hosts

2. Those that have switched hosts from one native species to another

3. Those that are more recent arrivals since human colonization Blue-Footed Booby

Reintroduction of CriticallyEndangered Species

Floreana Mockingbird

Early Warning System

Galapagos Hawk
