released into the wild in 1997. These and later hand-reared birds were found to be too tame and naive; they would land on people's shoulders, or near cats and mongooses, which subsequently killed them. Jones decided to release the captive-bred birds after nine to ten weeks when fledging would normally occur, instead of seventeen, and these young birds were better at integrating with wild birds, and learning social and survival skills. Captive-bred birds who had learned to use feeding hoppers in captivity passed on this ability to wild birds, and the number of birds that fed at food hoppers and used nest boxes provided by the team increased in the following years. The birds had not used the nest boxes before 2001, after which they were improved in design. By 1998, there were 59–73 birds, including 14 that had been captive bred since 1997. By 2005, 139 captive birds had been released and intensive management of the wild population ceased in 2006. Since then only supplemental food and nest boxes have been provided. By 2007, about 320 echo parakeets lived in the wild, with numbers growing, and the species was downgraded from critically endangered to endangered on the 2007 IUCN Red List of Threatened Species; its numbers were still low overall and its range restricted. In 2009–2010, 78% of nesting attempts occurred in nesting boxes and a record of 134 chicks fledged during this breeding season. By 2016 the population had approached 700 birds. Though the echo parakeet is considered to have been saved from extinction, it still needs continued management by humans to stay secure from remaining threats. Since the carrying capacity of the Black River Gorges National Park had reached its limit, echo parakeets were released in the mountains of eastern Mauritius around 2016, and it has been suggested that birds could be introduced to the other Mascarene Islands. In 2015, Jackson and colleagues suggested that, due to their close genetic relatedness, the echo parakeet could be used as ecological replacements of the extinct Réunion parakeet and Newton's parakeet of Rodrigues, which would also secure the echo parakeet further. Since it has been suggested that some endemic trees and parrots on the Mascarenes co-evolved, reintroducing the echo parakeet could aid in seed-dispersal, a function previously carried out by its extinct relatives. Jackson and colleagues cautioned that the rose-ringed parakeet is seen as a crop-pest on Rodrigues and that
