2017 was even more disastrous, likely killing at least 32 birds, with only five females found during the post-hurricane survey of the area. However, in the spring of 2018, the estimated wild population was 12. As of February 2019, with the Houston Zoo having released many individuals the previous year, the wild population was around 200. Since then, the wild population has decreased again. A count done later that year indicated only 108 birds remaining and a report from February 2021 stated fewer than 100.
