From the author: North American populations of Mountain Plovers (Charadrius montanus) have declined 63% since 1966. Using radiotelemetry, we monitored plover nesting and brood rearing during the 1993 and 1994 breeding seasons in Weld County, Colorado. Our objectives were to extend preliminary breeding studies of 19Q2 (Miller and Knopf 1993) arrd to determine the minimum area required for successful reproduction by this species. Plovers began arriving on the breeding grounds in mid-March. Due to a high incidence of predation, eggs hatched in only nine of 34 (26%) nests in 1993 and in 20 of 54 (37%) nests in 1994. Daily survival rates of chicks were 0.957 (442 telemetry days, 44 chicks) and 0.951 (610 telemetry days, 42 chicks) each year, respectively. Plover broods moved an average 337 [+ or -] 46.5 m/day (N = 30) and 298 [+ or -] 41.9 m/day (N = 14) in 1993 and 1994 (t = 1.10, P = 0.27), respectively. Plovers that raised chicks to fledging used between 2B and 91 ha, averaging 56.6 [+ or -] 21.5 ha. daily movement rates (t = 0.7, P = 0.48) and fatal area used (t = 1.4, P = 0.17) were similar between broods where [less than or equal to] one chick fledged and broods from which no chicks fledged. success of plovers in raising chicks appeared related either to overall fox activity in the area or to how effectively the adult detected and distracted fixes. Most plovers left the breeding grounds in mid-to-late July, four months after arrival. Population declines of Mountain Plovers appear independent of any recent landscape fragmentation within this breeding stronghold of the species. Received 10 May 1995, accepted 1 Oct. 1995.
