Reproductive Success of Burrowing Owls in Urban and Grassland Habitats in Southern New Mexico

  title={Reproductive Success of Burrowing Owls in Urban and Grassland Habitats in Southern New Mexico},
  author={Daniele Berardelli and Martha J. Desmond and Leigh W. Murray},
Abstract We examined Burrowing Owl (Athene cunicuaria) reproductive success at 144 nests in urban (n  =  80) and grassland (n  =  64) habitats in southern New Mexico in 2000 and 2001. Nest success was higher in grassland compared to urban areas (81 vs. 68%) but urban landscapes fledged more young per successful nest (3.85 vs. 3.07). Mean fledging success per nest was similar between habitats with 2.60 and 2.50 fledglings in urban and grassland habitats, respectively. Fledging success was… 

Microscale nest-site selection by the Burrowing Owl (Athene cunicularia) in the pampas of Argentina

ABSTRACT Habitat modifications have led many bird species to occupy areas with different characteristics, including human-altered landscapes. In this study, we analyzed how land use influences the

Burrowing Owl (Athene cunicularia) Habitat Associations in Agriculture Fields and along Canal Trails in Phoenix, Arizona

Abstract Burrowing Owls (Athene cunicularia) have experienced significant population declines over the last 100 years in parts of the United States and Canada. This decline may be associated with

Burrowing owl nest distribution and density in relation to urban development

The results indicate that, unlike many raptors that are negatively affected by urbanization, burrowing owls may not be adversely impacted by nesting in areas with moderate levels of urban development.

Juvenile Burrowing Owl Nighttime Space-Use In Southern New Mexico

Abstract In some areas, Burrowing Owls (Athene cunicularia) occur in human-altered, urbanized environments. However, their use of these anthropogenic land-cover types during nighttime is not well

Juvenile burrowing owl movement and survival in a human‐altered landscape

Burrowing owls (Athene cunicularia) are increasingly moving into human-altered landscapes, yet it is not well-understood how these environments affect movements and survival. We studied postfledging

Burrowing Owl (Athene cunicularia) nest phenology influenced by drought on nonbreeding grounds

ABSTRACT Migratory birds are demonstrating changes in phenology linked to climate change. Understanding these changes requires connecting events that occur over the multiple regions occupied during

Evaluating cropland in the Canadian prairies as an ecological trap for the endangered Burrowing Owl Athene cunicularia

Anthropogenic development may influence the choices animals make and their resulting reproductive success and survival. If such choices are maladaptive, the impact of anthropogenic change can be

Habitat Selection by Burrowing Owls Athene cunicularia in the Pampas of Argentina: A Multiple-Scale Assessment

Abstract. Human-induced habitat changes have been typically linked to negative effects on native species, but an increasing number of studies show that many species are unaffected by these changes

Differing nest-defence behaviour in urban and rural populations of breeding Burrowing Owls

The role of behaviour is highlighted in explaining the ability of Burrowing Owls to live in a range of habitats, including successfully breeding in urban areas, and the importance of breeding stage on behavioural traits is emphasised.

Influence of urbanization on the distribution and defense strategies of the Burrowing Owl Athene cunicularia in the city of Uberlândia, southeastern Brazil

Urbanization causes drastic changes in habitat and species behavior. In birds, these changes influenced the extinction of some species. The Burrowing Owl Athene cunicularia (Molina, 1782) (Aves:



Comparative demography of Burrowing Owls in agricultural and urban landscapes in southeastern Washington

Anecdotal evidence suggests that Burrowing Owls have declined in the state of Washington. We examined the status of these owls in agricultural and urban habitats to better understand the underlying


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.

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.

Movements, activity patterns, and habitat use of burrowing owls in Saskatchewan

The breeding ecology of burrowing owls (Athene cunicularia) in central Saskatchewan was studied during 1982-83 and home range, activity patterns, and habitat used for foraging for 6 radiotagged adult male owls were determined.

Density and reproduction of burrowing owls along an urban development gradient

The results, combined with those of previous researchers, suggest that burrowing owls on the study area henefited from high prey densities around homes, but that increased human-caused nest failures and declines a the number of young fledged at successful nests in heavily developed areas offset the advantages of abundant prey.

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.

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.

A Comparison of Available Prey and Diet of Florida Burrowing Owls in Urban and Rural Environments: A First Study

Abstract. The distribution of the Florida Burrowing Owl (Athene cunicularia floridana) has expanded from primarily rural areas in south-central Florida to include urban/suburban areas to the north,


Results, and auxiliary diet information, suggest rodents were infrequent in the diet of Burrowing Owls in the Imperial Valley and may help explain their lower reproductive success relative to other areas of California.

Do land-use patterns influence nest-site selection by burrowing owls (Athene cunicularia hypugaea) in northeastern Colorado?

It is difficult to generalize about the effects of landscape fragmentation on burrowing owls because any effects are probably a complex function of local habi- tat structure, landscape structure, and local prey and predator availability.
