Mean ± SE values of reproductive parameters describing the nesting chronology of food-supplemented and control Wrentit pairs during the 2000–2002 breeding seasons in San Deigo County, Californa. Wrentits nested earlier, attempted more nests, and had an extended breeding season when given supplemental food (“food”) in a year of average rainfall (2001) compared to Wrentits without supplemental food (“control”) and in a drought year (2002). Wrentits were not monitored in the first half of 2000, so data are unavailable (ND) for most reproductive parameters. Sample sizes are given in parentheses. All dates are given as day of year, where day 90 = 31 March and day 170 = 19 June.
