On September 26 , 2017 , 6 crows were released into the Pu'u Maka'ala Reserve . In contrast to the previous release , the group released was made of 4 males and 2 females rather than just males . On October 11 , 2017 , another group of 5 crows , 3 males and 2 females , was also released into the area . The first group introduced also formed social groups similar to those expected of the species , and also responded to stressors in the environment , showing awareness of surroundings . As of 2018 , they have been described as " thriving " , though they may have been negatively affected by the 2018 lower Puna eruption , which impacted at least a third of the Malama Kī Forest Reserve , an important habitat for the Hawaiian crow and other endangered Hawaiian wildlife . Following the success of the previous year 's introduction , another 5 were reintroduced to the Pu'u Maka'ala Reserve on September 25 , 2018 . In late 2018 , one of the crows released in 2017 , a male named Maka'ala , was found dead due to wounds likely from a predatory attack followed by scavenging
