Summary
The live stock of the extremely endangered Bald Ibis is still declining. The eastern population is extinct. The remaining three small colonies are concentrated at the Moroccan atlantic coast. In 1989, we recorded 43 breeding pairs with 89 chicks. Within the colonies there were also 15 yearlings and 15 individuals two years old. In January 1990, we found three subadults at the colonies together with the breeding pairs. The rest of the young birds (28) we located at the mouth of the river Tanri.
