Identification
Adults easily identified by their dark heads and pale yellow crown and cheek stripe. Imature birds may resemble adult Striated Heron, but are significantly taller, longer-legged and have large red (not yellow) eyes. Juvenile night herons can be distinguished from juvenile Striated Herons in a similar fashion.
Description
Adult is overall blue-grey with bold black markings on their back, yellow legs, black head with pale yellow crown, cheek stripe and head plumes, thick black bill and large, bright red eyes. Imatures similar to adults, but pale yellow head markings are faded. Sexes are similar. Juveniles are overall dark brown with extensive white streaks on their heads and underparts and white spots on their upperparts.

Conservation
Vulnerable. With a total population of roughly 10, 000 mature individuals, this species is ranked as ‘vulnerable’. It has been extripated from Rabida and Santiago and populations across Santa Cruz and southern Isabela have been greatly reduced. It is threatened by invasive predators such as cats, dogs, pigs and rats that prey on its eggs young.
