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 over time is lacking. Published population trends from the North American Breeding Bird Survey program suggested that Burrowing Owl populations in the US have declined over the past 60 yr, but the declines were not considered significant until 2014. However, accurate trend estimates and the… 

Long-Term Population Fluctuations of a Burrowing Owl Population on Kirtland Air Force Base, New Mexico, USA

Abstract. Western Burrowing Owls (Athene cunicularia hypugaea; hereafter, Burrowing Owls) were once widespread residents of grasslands throughout western North America, but their range has

Genetic Variation among Island and Continental Populations of Burrowing Owl (Athene cunicularia) Subspecies in North America

Despite the extensive geographic distribution of the Western Burrowing Owl, it is found genetic differentiation between the panmictic population north of the Trans-Mexican Volcanic Belt and the resident Texcoco Lake population in central Mexico.

Burrowing owls (Athene cunicularia) often stand on a fence post or on top of a mound of dirt, bobbing their heads, looking at you with large yellow eyes, and standing tall on their long legs (color

Prey Delivery Inside an Artificial Nest Box and Burrows Used by Nesting Burrowing Owls in el Paso, Texas

Abstract. Determining the diet of species that nest underground, such as the Burrowing Owl (Athene cunicularia), is challenging. Prey information for Burrowing Owls is often limited to prey remains


The next generation of smart phones will be able to recognise each other's voices and provide real-time information about what the other is doing and what they are thinking about.



Factors Affecting Detection of Burrowing Owl Nests During Standardized Surveys

Abstract Identifying causes of declines and evaluating effects of management practices on persistence of local populations of burrowing owls (Athene cunicularia) requires accurate estimates of

Habitat feature important to burrowing owl breeding success in Saskatchewan

Burrowing Owls are unique among owls in that they nest in mammal burrows (usually ground squirrel or badger burrows in western Canada). They nest as solitary pairs or small loose colonies in open


A•STRACT.---Populations of western Burrowing Owls (Athene cunicularia hypugaea) in New Mexico were assessed using a variety of approaches: 1) multi-year studies at three specific sites; 2) a

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.

Burrow Occupancy Patterns of the Western Burrowing Owl in Southern Nevada

ABSTRACT. Understanding long-term patterns of burrow occupancy for the Western Burrowing Owl (Athene cunicularia hypugaea) is necessary for the conservation of this species, especially in arid,

Correlations Between Burrowing Owl and Black- Tailed Prairie Dog Declines: A 7-Year Analysis

Efforts are needed to ensure preservation of black-tailed prairie dog colonies for burrowing owls and other species associated with this prairie ecosystem, and to better monitor changes in burrowing owl and prairieDog populations.

Distributional Changes in the Western Burrowing Owl (Athene cunicularia hypugaea) in North America from 1967 to 2008

The western Burrowing Owl has experienced an intriguing southward shift in the northern half of its breeding range, contrary to what is predicted by most species niche models and what has been observed for many other species in North America.

Population density of the western burrowing owl (Athene cunicularia hypugaea) in Mexican prairie dog (Cynomys mexicanus) colonies in northeastern Mexico

The western burrowing owl (Athene cunicularia hypugaea) occurs throughout western North America in various habitats such as desert, short-grass prairie and shrub-steppe, among others, where the main

Burrowing Owl nest success and burrow longevity in north central Oregon

It is recommended that habitat used by livestock be evaluated for use by Burrowing Owls, that occupied areas be managed to minimize destruction of burrows by livestock, and that predator-control efforts be revised to exclude mortal- ity of badgers.

Demography of the Burrowing Owl in Badlands National Park

The burrowing owl (Athene cunicularia), was once widely distributed throughout the western United States and Canada (Bent 1938), and was considered common on the prairie dog towns of South Dakota and
