Ecology and behaviour
Like in other true weaver birds, the roofed nest is woven from strips of grass leaf, but the Sakalava weaver also uses strips of palm fond, or thatching and weaving materials collected in villages. The top is woven directly around a branch or it is attached from a short woven stalk. It is shaped like a
