Three Birds, Three Outcomes

Three different birds, three different outcomes at the hands of humans. The Passenger Pigeon once numbered in the billions, yet human exploitation drove it to extinction a century ago. The Kirtland's Warbler had dwindled to fewer than 200 singing males in 1971, yet today we know how to maintain healthy populations. The Whooping Crane was down to 23 individuals – twice – and its fate still remains an open question. What can these three birds tell us about how to coexist with other species?
