The effects of management practices on grassland birds—Loggerhead Shrike (Lanius ludovicianus)

The key to Loggerhead Shrike ( Lanius ludovicianus ) management is providing open grasslands with scattered trees and shrubs for foraging, nesting, and perching. Loggerhead Shrikes have been reported to use habitats with 20–266 centimeters (cm) vegetation height, greater than or equal to (≥) 10 percent grass cover, 3–48 percent forb cover, 2–25 percent shrub cover, 3–40 percent bare ground, and 11–67 percent litter cover.

The effects of management practices on grassland birds—Burrowing Owl ( Athene cunicularia hypugaea )

Keys to Burrowing Owl ( Athene cunicularia hypugaea ) management include providing areas of short, sparse vegetation and maintaining populations of prey species and of burrowing mammals to ensure availability of burrows as nest sites. In particular, the conservation of black-tailed prairie dog ( Cynomys ludovicianus ) and Richardson’s ground squirrel ( Urocitellus richardsonii ) colonies is vital to the preservation of Burrowing Owls on the Great Plains. Burrowing Owls have been reported to use habitats with less than 31 centimeters (cm) average vegetation height, 5–12 cm visual obstruction reading, 12–36 percent grass cover, 29–45 percent forb cover, 1–11 percent shrub cover, 11–58 percent bare ground, and 6–27 percent litter cover.

The effects of management practices on grassland birds—Sprague’s Pipit ( Anthus spragueii )

Keys to Sprague’s Pipit ( Anthus spragueii ) management include providing suitable grassland habitat, especially native prairie, with intermediate vegetation height and low visual obstruction, and controlling succession therein. Sprague’s Pipits have been reported to use habitats with no more than 49 centimeters (cm) average vegetation height, 4–14 cm visual obstruction reading, 15–53 percent grass cover, less than (<) 21 percent forb cover, <18 percent shrub cover, <44 percent bare ground, 10–63 percent litter cover, and less than or equal to 11 cm litter depth.

The effects of management practices on grassland birds—Northern Harrier ( Circus hudsonius )

The key to Northern Harrier ( Circus hudsonius ) management is providing tall, dense vegetation in extensive mesic or xeric grasslands or in wetlands. Northern Harriers have been reported to use habitats with 15–106 centimeter (cm) average vegetation height, 28–75 cm visual obstruction reading, 24–53 percent grass cover, 18–25 percent forb cover, less than or equal to 2 percent shrub cover, 3–5 percent bare ground, 23–30 percent litter cover, and 2–6 cm litter depth.

The effects of management practices on grassland birds—Willet ( Tringa semipalmata inornata )

Keys to Willet ( Tringa semipalmata inornata ) management include providing large expanses of native grasslands and wetland complexes. Wetland complexes should contain a diversity of wetland sizes and classes, such as ephemeral, temporary, seasonal, semipermanent, and permanent wetlands, as well as intermittent streams. Willets use wetlands of various salinities. Willets require short, sparse upland grasslands for nesting and foraging and wetland complexes for foraging. Broods use taller, denser grass cover than do nesting adults. Willets have been reported to use habitats with less than or equal to 70 centimeters (cm) average vegetation height, 4–23 cm visual obstruction reading, 15 percent bare ground, 38 percent litter cover, and 1–9 cm litter depth.

Distribution of burrowing owls in east-central South Dakota

Western burrowing owl (Athene cunicularia hypugaea) populations have declined across much of western North America, particularly at the northern and eastern edges of the species&rsquo; breeding range (Martell et al. 2001, Murphy et al. 2001, Shyry et al. 2001, Skeel et al. 2001, Klute et al. 2003). In South Dakota, the burrowing owl is a summer resident that historically was relatively common throughout the state, but its range has decreased in recent decades, especially in the eastern half of the state (Whitney et al. 1978, South Dakota Ornithologists&rsquo; Union [SDOU] 1991, Peterson 1995). Tallman et al. (2002) described the species as uncommon to locally common in western South Dakota, uncommon in the north-central part of the state, and casual (i.e., not within the species&rsquo; normal range, but with 3&ndash;10 records in the past 10 years) elsewhere in the eastern half. The burrowing owl is a Species of Greatest Conservation Need (South Dakota Department of Game, Fish and Parks [SDGFP] 2006) and a Level I Priority Species in South Dakota (Bakker 2005).
