This study on the biology and reproductive behavior of Sporophila lineola (Linnaeus, 1758) was carried in a Citrus reticulata Blanco plantation near Campinas, Brazil. A blind was used for observations near the four nests. These were built on the branches of C. reticulata, and were made of grass roots. The clutch varies from two to three eggs. Both male and female or only female, feed the nestings with insects such as dragonfly and caterpillar, carried across their bill.
