text: This bird was long considered to be conspecific with the closely related North American species, the green heron, which is now usually separated as B. virescens, as well as the lava heron of the Galápagos Islands (now B. sundevalli, but often included in B. striata, e.g. by BirdLife International); collectively they were called "green-backed herons".
