Camargue. This species is not considered established in mainland Spain. The Barcelona Zoo kept a small free-flying population which bred in the zoo and at least once in 1974 in the surrounding city park. Between 1983 and 1985 they had increased to 18 birds, but these subsequently declined to 4–6 pairs in the 1990s and the birds were permanently caged by the end of the 1990s (the zoo still has some). In 2001 the remaining birds in the surroundings were culled, thus ending the occurrence of the species in the 'wild' in the area. However, in the early 2000s vagrants most probably from France were recorded in northern Catalonia, and sporadic observations throughout the year have been recorded since then along the Mediterranean and Cantabrian coasts. There were a total of about twenty approved records of sightings between 1994 and 2004. As of 2009, birds entering Spain from France are shot. The population in Italy may have been introduced from the zoo Le Cornelle which has kept a free-flying group since the early 1980s, or possibly from Brittany, but this is unclear. The first pair was seen breeding in the nearby heronry at Oldenico, in Lame del Sesia Regional Park in Novara, NW Italy, in 1989. By 1998 there was a colony of 9 pairs and 48 birds there; by 2000 there were 24–26 pairs, and by 2003 there were 25–30 breeding pairs. A second colony appeared in 2004 at another nearby heronry at Casalbeltrame. These birds would mostly feed in the rice fields in the area, but would also migrate elsewhere during the summer, with the population at the roosts increasing in the winter. In 2008, the number of breeding ibis was estimated at 80–100 pairs, and at least 300 birds. That same year, six individuals, consisting of three pairs, were observed roosting at a heronry in Casaleggio. By 2009 they were said to be one of the most characteristic animals of the rice-growing area of Novara and Vercellese. In 2010 the species was reported attempting to breed in the Po Delta, northeast Italy. By 2014 reports of individuals and small flocks were recorded in various areas from the Po Valley down to Tuscany. Outside the Piedmont Region, cases of possible nesting are reported in Emilia-Romagna, Veneto and Lombardy. As of 2017 there do not seem to be coordinated control efforts in Italy. In the Netherlands, sacred ibises were
