Tracking the migratory routes of songbirds is now easy
songbird populations have been declining over the last half century. Understanding their annual migration would aid conservation measures. A study has used coin-sized geolocators to track the migration of two species of songbirds. This has thrown up new information: songbirds travel much faster than previously known.
Initially information on migration was dependent on chance capture of previously tagged (with metal bands) birds.
