Concern over the status of species associated with prairie dog colonies has increased with the recent proposed listing of black-tailed prairie dogs (Cynomys ludovicianus). We monitored burrowing owl (Athene cunicularia) populations and prairie dog densities in 17 black-tailed prairie dog colonies in the Nebraska panhandle between 1990 and 1996. All prairie dog colonies were controlled at least once during the study. We observed a 63% decline in nesting pairs of burrowing owls and significant… 

Factors Influencing Burrowing Owl Abundance in Prairie Dog Colonies on the Southern High Plains of Texas

The number of nesting Burrowing Owl pairs was positively correlated to colony area, but numbers and reproductive rate were not related to measures of vegetative composition and structure in prairie dog colonies, nor to indices of prey availability.

Occurrence and Habitat Characteristics of Burrowing Owl Nests in Gunnison's Prairie Dog Colonies of Northeastern Arizona

Recent declines of Gunnison's prairie dogs could adversely affect this owl, considered uncommon in northern Arizona, and habitat characteristics at Burrowing Owl nest burrows were studied.

Factors affecting Burrowing Owl occupancy of prairie dog colonies

Colonial attributes and loss of prairie dog colonies to sylvatic plague affected the occupancy of those colonies by Burrowing Owls in north-central Montana and the results reaffirmed the importance of colony size.


In general, Burrowing Owls that arrived early, initiated clutches sooner, and either nested at greater distances from nearest neighbors or had fewer owl nests within 250 m of the nest burrow, had larger clutches, larger broods, and more fledglings.

Multiscale Habitat Selection by Burrowing Owls in Black-Tailed Prairie Dog Colonies

Action is recommended to ensure persistence of the remaining prairie dog colonies as an important management strategy for burrowing owl conservation in the Great Plains of North America.

Influence of local and landscape characteristics of Prairie Dog colonies on Burrowing Owl nest ecology in South Dakota

Evaluated habitat factors affecting a population of burrowing owls at the eastern extent of their range lend support for the value of maintaining prairie dog colonies to ensure the persistence ofBurrowing owl populations in the Great Plains ecosystem.


Monitoring of radio-tagged juveniles during the postfledging period in the Little Missouri National Grassland, North Dakota, found mortality was highest during the first two weeks after nest departure when juveniles were flightless, and two to three weeks later when juveniles became independent.

Tree Cover in the Surrounding Landscape Reduces Burrowing Owl (Athene cunicularia) Occupancy of Black-Tailed Prairie Dog Colonies in South Dakota

Abstract. Burrowing Owl (Athene cunicularia) population declines have led to the owl's designation as a species of conservation concern in South Dakota. Burrowing Owls nest primarily in black-tailed

Occupancy of Mountain Plover and Burrowing Owl in Colorado

Abstract Concern over the decline of grassland birds has spurred efforts to increase understanding of grassland bird–habitat relationships. Previous studies have suggested that black-tailed prairie

Spatial and Temporal Patterns In Population Trends and Burrow Usage of Burrowing Owls In North America

Abstract Many researchers have suggested that abundance of Burrowing Owls (Athene cunicularia) has declined in many portions of their breeding range, but a thorough review of their population trends



Factors Influencing Burrowing Owl (Speotyto cunicularia) Nest Densities and Numbers in Western Nebraska

As the size of prairie dog towns increased, burrowing owls occurred in higher numbers but lower densities, andBurrow availability may be a limiting factor for owls nesting in pastures with badger burrows.

Spatial patterns of burrowing owl (Speotyto cunicularia) nests within black-tailed prairie dog (Cynomys ludovicianus) towns

The spatial patterns of burrowing owl nests in black-tailed prairie dog towns were examined in the Nebraska panhandle during the spring and summer of 1989–1991 and it was not possible for owls to demonstrate patterns other than random in the smaller towns, but choice of nest sites by pairs resulted in a clumped nest distribution.

Spacing and Ecology of North American Badgers (Taxidea taxus) in a Prairie-Dog (Cynomys leucurus) Complex

Spacing patterns of males were similar to those reported in other studies, but females were more territorial than reported elsewhere, and home ranges of females were larger during the breeding season than during the nonbreeding season.

The Evolution of Coloniality in White‐tailed and Black‐tailed Prairie Dogs (Sciuridae: Cynomys Leucurus and C. Ludovicianus)

An analysis of prairie dog foraging patterns indicated that there is no social facilitation of foraging in terms of either group hunting of either large or elusive prey, the location of large, scattered food supplies, or modification of the soil in order to effect the growth of vegetation that is more favorable or more abundant than that which would otherwise result.

Flora and fauna associated with prairie dog colonies and adjacent ungrazed mixed-grass prairie in western South Dakota.

Prairie dog grazing decreased mulch cover, maximum height of vegetation, plant species richness, and tended to decrease live plant canopy cover compared to that on ungrazed mixed-grass prairie.

The Prairie Dog and Biotic Diversity

Since the turn of this century, prairie dog populations have declined as much as 98% throughout North America, largely as a result of prairie dog eradication programs. The prairie dog is a keystone

Paleobiology, biogeography, and systematics of the black-footed ferret, Mustela nigripes (Audubon and Bachman), 1851

Ferrets show a high degree of sexual dimorphism, with discriminant analysis correctly classifying 95% of all specimens to sex and Ferrets also exhibit north-south clinal variation in size, but they do not appear to exhibit variation based on species of Cynomys associate.

Some Consequences of Competition between Prairie Dogs and Beef Cattle.

The presence of prairie dogs appears to improve herbage quality, thus partially compensating the reduction in herbage avaibrble to steers, and the influence of pralrie dogs on the herbage crop did not cause a significant reduction in steer weight gains.

Current status, distribution, and conservation of the Burrowing Owl ( Speotyto cunicularia ) in midwestern and western North America

The Burrowing Owl (Speotyto cunicularia) inhabits open prairie grassland habitat in the midwestern and western US and Canada. For several years now, numbers of this species in North America have been


It is suggested that reduced predation on eggs and young, resulting from both gr ouLp defense and "selfish herd" effects, is an important advantage of Bank Swallow coloniality.
