Closely related to E. garzetta, which it closely resembles, differing in smaller size, with male wing 260 vs 280 and “typical adult mass” 369 g vs 490–614 g (for males and females in Hungary)#R#R (1); brighter, golden-yellow vs lemon-yellow feet when not breeding, with variable-length yellow stripe extending up rear of tarsus on almost all individuals#R (2); white feathers of forehead not extending so far down towards bill base (i.e. lore colour extends more as bridge over base of mandible)#R (ns); when breeding, elongate, bushy, filamentous crest-like crown and neck plumes vs non-elongate crown and neck feathers except for two very long lanceolate (not filamentous) feathers (3); when breeding, longer and strongly recurving (“bouncing”) back plumes (2). Somewhat larger race brewsteri provisionally accepted, but differences possibly trivial or even invalid (based only on average measurements). Two subspecies tentatively recognized.
