Saving Birds From Extinction by Discovering Their Habitats

Abstract

With only 700 individuals left in the wild, the northern bald ibis is considered to have a moderate risk of going extinct. What does it take to prevent a species from going extinct? Aside from ensuring there is adequate habitat and making sure the species is safe, knowledge about an animal’s behavior is key for conservation management. Which sites do these birds use for foraging and roosting? Do they move alone or in groups, and are there recurring patterns to their movements? These are just some of the questions we tried to answer in our study. We monitored the movements of 32 free-flying northern bald ibises over 4 years, by equipping the birds with GPS transmitters. We found that our birds are pretty predictable in their habits and that they preferably fly along valleys. Being aware of such preferences is important when planning to reintroduce new colonies into the wild.
