Our Mission: BRI works to assist threatened and recovering bird populations around the world by supporting research, reintroduction programs and habitat conservation initiatives that focus on immediate bird survivability and population stabilization. BRI does this work through a combination of public education, training, and direct support of scientific field and research projects. Our Philosophy: BRI believes that population stabilization efforts must begin early before population levels for an endangered bird species drop far below their critical threshold number. Every effort should immediately be made to achieve growth toward the critical threshold population size as soon as biologists establish the threshold number.
