Spix's Spinetail is very active and moves constantly in dense cover (Belton 1984). Behavior is typical of Synallaxis spinetails: hopping or creeping in dense cover, and typically perching in the open only when singing (Ridgley and Tudor 1994).

Around the nest, the male has been observed moving from side to side within 15-20 meters of the nest while singing. The female moves smoothly and silently in the vegetation around the nest (Pereyra 1927).
