1Humans hunted and killed almost all northern bald ibis birds by the 17th century.
2But breeding and rewilding efforts over the last 20 years helped grow the bird population.
3However, the birds do not know which direction to fly to migrate without the guidance of wild-born birds.
4So, humans are helping the birds learn their migration path.
5The northern bald ibis once flew over North Africa, the Arabian Peninsula and much of Europe, including southern Germany's Bavaria.
6People liked eating the migratory birds, and they disappeared from Europe.
7A few groups of the birds survived in other places.
8In 2002, a conservation and research group based in Austria stepped in to help.
9The group is called Waldrappteam; the birds are called Waldrapp in German.
10Scientists at Waldrappteam raise the birds and teach them how to fly to warmer areas.
11Johannes Fritz is a biologist working with the team.
12He said, "We have to teach them the migration route."
13Fritz and the Waldrappteam have increased the number of northern ibis in Central Europe from zero to almost 300 since the start of their project in 2002.
14Fritz said the group's work is the first attempt to reintroduce a continentally extinct migratory bird species.
15He said his team found that, when released, the birds raised by humans flew in the wrong direction and died in the winter.
16The humans have led the birds now for 17 years to places like Tuscany, Italy.
17Due to climate change, they have had to change the route to a winter home.
18Now they help the birds fly to Andalusia in southern Spain.
19To prepare them for travel, the humans begin working with the baby birds, or chicks, when they are just a few days old.
20The foster parent humans want the birds to connect with them so they will trust them along the migration route.
21Barbara Steininger is one Waldrappteam foster mother. She said she acts like "their bird mom."
22"We feed them, we clean them, we clean their nests. We take good care of them and see that they are healthy birds," she said.
23"But also we interact with them."
24Steininger and the other foster parents then sit on the back of a very small aircraft, waving and cheering for the birds as they fly.
25Fritz knew his work would be possible because he saw the work of Canadian inventor and naturalist Bill Lishman.
26Lishman taught Canadian geese to fly alongside his small plane beginning in 1988.
27He later guided endangered whooping cranes through safe routes.
28Fritz's team efforts have worked.
29The first bird independently migrated back to Bavaria from Tuscany in 2011.
30The team hopes the Central European population will be more than 350 birds by 2028 and will not need human help to migrate.
31This year, the route to Spain is longer than last year's path.
32Earlier this month from an airfield in upper Bavaria, the team guided 36 birds along one stage through blue skies and a wind from behind them that increased their speed.
33The full journey to Spain could take up to 50 days.
34Fritz said the effort is bigger than just the northern bald ibises.
35He hopes the group's work offers a possibility for helping other threatened migratory species to fly.
