Scott Sillett is a research wildlife biologist and head of the Smithsonian Migratory Bird Center. He investigates the ecology and behavior of both migratory and resident bird species. His research emphasizes experimental and multi-decade studies of wild bird populations. Sillett joined the Smithsonian Migratory Bird Center in 2002

Sillett's projects include:

• Behavioral and demographic responses of migratory birds to environmental variation

• Integrating knowledge of local adaptation, ecosystem engineering and anthropogenic effects into conservation efforts for island birds

• Ecology of bird populations throughout the annual cycle
