I determined the renesting intervals of female Sprague's Pipits in south-central Saskatchewan and also summarized data about incubation and nestling periods of Sprague's Pipits in Saskatchewan and Manitoba to provide more robust estimates of these life-history parameters. Two of eight radio-marked females initiated replacement clutches after failed nesting attempts, with renesting intervals of 11–13 and 15–16 d, respectively. Of 74 banded females, 3 were subsequently recaptured at later nests during the same breeding season. Nests of two of these females failed due to inclement weather and their renesting attempts were initiated 6 and 7–11 d later, respectively. The third female successfully fledged young and then initiated another nest 17 d later. The new nests of females that renested were all located less than 150 m from previous nests. Incubation and nestling periods for known-aged nests ranged from 12 to 15 d (13.4 ± 0.3 [SE], N= 9) and 11 to 14 d (12.1 ± 0.2, N= 39), respectively. Variation in the length of both incubation and nestling periods was likely a function of prolonged periods of inclement weather. More data are required to determine the extent of renesting in different habitats and the extent to which Sprague's Pipits are capable of successfully raising multiple broods in a single breeding season. SINOPSISes Anthus spragueii es una de las aves menos estudiadas en los Estados Unidos, en donde la mayor información sobre su bilogía reproductiva esta basada en observaciones anecdóticas de pocos nidos. Aquí, cuantifico y describo los intervalos de reanidación de hembras marcados de Anthus spragueii en el centro-sur de Saskatchewan, y también revise datos sobre periodos conocidos de incubación y polluelos de Anthus spragueii en Manitoba para proporcionar mejores estimativos de estos parámetros que hacen parte de las historias de vida. Dos de las ocho hembras con radios y marcadas iniciaron el reemplazo de la nidada después del fracaso de la anidación, con intervalos de reanidación de 11–13 y 15–16 días. De las 47 hembras anilladas, tres fueron recapturadas durante la época reproductiva; dos pertenecientes a nidos que fracasaron debido a la inclemencia del clima y una que crío exitosamente a sus polluelos. Intentos de reanidación se iniciaron 6, y 7–11 días después del fracaso de la anterior nidada y 17 días después de la salida de los polluelos del nido. Todas las reanidaciones ocurrieron en un rango de 150 m del nido anterior. Incubación y periodo de polluelos de nidos en los que se sabe su edad variaron entre 12–15 días (13.4 ± 0.3 [SE], N= 9) y 11–14 días (12.1 ± 0.2, N= 39), respectivamente. Variación en el periodo de incubación y polluelos fue probablemente debido a periodos prolongados de un clima inclemente. Más datos son necesarios para determinar la capacidad de reanidación en diferentes hábitats y la capacidad en la cual Anthus spragueii es capaz de criar exitosamente múltiples nidadas en una misma temporada reproductiva.
