I am afraid more of safety of Spanish-derived birds, which in northern Morocco are at increased risk of pesticide poisoning and shooting.

Maybe it would be worthwhile to re-introduce Bald Ibises in a second region of Iberian Peninsula?

Wow! We should not exaggerate things and start asking negative questions when we have zero data, that's called (choose your word).

Just a reminder, migratory birds belong to all the lands they visit, so obviously these visiting birds are ours as well (that means we can take care of them as well, as we took/take care of the only wild and viable population in the world).

It would be interesting to extract ancient DNA from those bones of Bald Ibis from European Middle Ages settlements and see their relations. Anyway, it seems that Moroccan and Middle Eastern populations are very similar anyway, below the level of subspecies.

Breeding season 2018 in Morocco

Good breeding season for the Northern Bald Ibis in Morocco. In 2018, a record number of 147 breeding pairs produced 170 juveniles.

These good results, year after year, are the main reason why the species was down-listed from ‘Critically Endangered’ to ‘Endangered’ in late 2018.
