Breeding

The breeding season for Striped Sparrow is from May-September (Rising 2011), but females collected in early April with greatly enlarged ovaries might possibly indicate an earlier onset of the breeding season (Sutton and Burleigh 1940). Breeding dates in Oaxaca, Mexico have been noted from 25 May (enlarged follicle) to 12 September (pre-juvenile; Forcey and Aragon 2009).

The nest is cup shaped and composed of pine needles, twigs, grasses, and/or straw and lined with fine plant material (Byers et al. 1995, Howell and Webb 1995, Rising 2011). The nest is placed low to the ground, often in a thick bush or in bunchgrass (Byers et al. 1995, Howell and Webb 1995, Rising 2011). Clutch size ranges from 3-4 eggs, which are white marked with grayish brown to grayish lilac (Byers et al. 1995, Howell and Web 1995, Rising 2011) or marked with reddish browns or purples (Howell and Webb 1995). The female incubates for 13–14 days (Byers et al. 1995).
