The Northern Bald Ibis Geronticus eremita is a globally threatened species with its main remaining world population breeding in an area of sea cliffs and coastal semi‐desert steppe near Agadir in southern Morocco. Between 1998 and 2002, we showed experimentally that the small‐scale provision of fresh water near the breeding colonies led to an increase in the productivity of the birds. The increase was greatest in years with low natural rainfall but was positive in all years tested. The supplementary fresh water appears to help buffer productivity against the impacts of low rainfall and its provision is now part of the ongoing conservation measures for this species.

“…By 1995 a total population of c. 300 birds was breeding in three subcolonies within the Parc National de Souss-Massa, and in one colony at Tamri (Bowden, 1998). There is some movement between these sites, which are c. 100 km apart (Bowden et al, 2003; El Bekkay et al, 2007).…”

The northern bald ibis Geronticus eremita was once widespread throughout the Middle East, northern Africa, and southern and central Europe. Habitat destruction, persecution and the impacts of pesticides have led to its disappearance from most of its former range. It disappeared from central Europe > 400 years ago, but has persisted as a relict and slowly growing breeding population in Morocco, where c. 700 wild birds of all ages remain. In Algeria, the last confirmed breeding was in 1984; in Turkey the fully wild population disappeared in 1989, but a population remains in semi-wild conditions. In Syria a small population was rediscovered in 2002, only to subsequently decline to functional extinction. Restoration programmes have been initiated independently in several locations, with over 300 free-flying birds resulting from reintroduction projects in Austria, Germany, Spain and Turkey, to restore both sedentary and fully migratory populations. Maintaining current efforts in Morocco remains a high conservation priority.

“…Thus, only four colonies have survived on the Atlantic coast in south-west Morocco, three in the Souss-Massa National Park (SMNP) and one in Tamri (Table 2) (Bowden and Smith 1997, Thévenot et al 2003, Bowden et al 2003, 2008). Finally, the creation of the Souss-Massa National Park in 1991 and conservation measures implemented since 1993 resulted in an increase of the last wild NBIs from 59 breeding pairs in 1997 to 147 breeding pairs and a total of 708 individuals in 2018, including non-breeding and juvenile birds (El Bekkay et al 2007, Oubrou and El Bekkay 2018). In 2017, two new small breeding colonies on the Atlantic coast north of Tamri were discovered (Aourir et al 2017) and in 2018 two additional new sites were found in the SMNP on the Atlantic coast (Oubrou and El Bekkay 2018).…”

SummaryThe Northern Bald Ibis (NBI) Geronticus eremita, is an ‘Endangered’ bird species of which only very few wild breeding colonies have survived along the Atlantic coast of south-west Morocco. This paper analyses ecological conditions of the 72 breeding sites of the NBI that have been known since 1900 in Morocco. Characterisation of breeding sites is based on physical criteria (elevation above sea level, geomorphology, mean annual precipitation and types of landscape) as well as land use, vegetation cover, infrastructure and types of settlement within three perimeters (0–1 km, > 1–5 km and > 5–10(20) km) using Google Earth satellite images. Statistical analyses of the number of breeding pairs, fledglings and rainfall during different quarters of the year from 1994 to 2016 in the two remaining breeding sites in Souss-Massa National Park and Tamri showed expected patterns as well as unexpected differences between the two localities. Based on our findings and indications in the literature, we suggest general and specific recommendations for potential future translocation projects of the NBI. Based on the analysis of the 28 breeding colonies existing after 1977, two elements emerge as the most important prerequisites: a low level of disturbances at the breeding sites and adequate feeding areas at a reasonable distance of 5–15 km.
