Storm's Stork (Ciconia stormi) isn't an endemic species but considered to be the rarest Stork in the world. They primarily occur in lowland tropical forests of Indonesia, Malaysia, and Southern Thailand. Deforestation of its native habitat is believed to be their main threat. I was lucky to find this very obliging individual on the car trail inside Way Kambas National Park in Lampung.
