“…Owls tend to display territorial behaviour during breeding season by responding vocally to warn intruders (Haug & Didiuk 1993;Mori et al 2014;Moulton et al 2004) and protect their nest (Mori et al 2014;Moulton et al 2004). Such greater vocal response can also be observed during early breeding season which is likely due to territorial and/or nest establishment and defence (Boal & Bibles 2001;Mori et al 2014;Moulton et al 2004). Therefore, broadcasting conspecific calls during the breeding season could provoke individuals to be more aggressive in responding vocally.…”

“…For many owl species, males actively display vocal activities to defend their territory (Currie et al 2004;Moulton et al 2004;Takagi et al 2007b) and attract mates (Boal & Bibles 2001;Jacobsen et al 2013). Owls tend to be more vocally responsive during the breeding season (Haug & Didiuk 1993;Moulton et al 2004) but such behaviour decreases throughout the nesting season (Boal & Bibles 2001).…”

“…Owls tend to be more vocally responsive during the breeding season (Haug & Didiuk 1993;Moulton et al 2004) but such behaviour decreases throughout the nesting season (Boal & Bibles 2001). Males may cease singing almost immediately after pairing in courtship (Konig & Weick 2008) while females may become less vocally responsive during the incubation period (Haug & Didiuk 1993;Takagi et al 2007a).…”

“…Density overestimation may occur when: Individuals lured by call playback moved to a different location (Moulton et al 2004;Wiens et al 2011) and thus counted more than once (Borges et al 2004;Hannah 2009) and/or; An owl species may have different vocal responses to playback and this can influence the actual count (Borges et al 2004;Wiens et al 2011). On the other hand, underestimation of density may occur when certain individuals did not react to call playback (Hannah 2009;Haug & Didiuk 1993;Takagi et al 2007a).…”

“…Sparse and low vegetation, such as that in grasslands and steppes, characterizes burrowing owl habitat (Haug et al 1993), but owls can be abundant in agricultural areas (Conway et al 2006;Moulton et al 2006;Restani et al 2008). Adult owls frequently nest in loose colonies (Lantz et al 2007), but they also defend the space around their nests from conspecifics (Moulton et al 2004). Northern burrowing owl populations are generally obligate migrants, whereas those to the south are year-round residents.…”

Western burrowing owls (Athene cunicularia hypugaea) are ground-dwelling owls distributed throughout western North America. Because of population declines, this species is considered endangered in Canada, and burrowing owls are listed as a species of conservation concern in states of the western USA. Korfanta et al. (2002) previously presented primers for seven microsatellite loci in burrowing owls. Parentage and relatedness studies require a larger number of markers for accuracy and precision. Here, we developed and characterized 18 additional microsatellite DNA loci, and we tested these loci in 23 individuals. The number of alleles per locus ranged from 2 to 11; two loci deviated from Hardy-Weinberg equilibrium following Bonferroni correction; we did not detect linkage disequilibrium following Bonferroni correction; and the probability of exclusion for parent pairs using all loci was [0.9999. We envision these loci will facilitate detailed analyses of the genetic mating system of burrowing owls, which is poorly understood.

Survival and fidelity of translocated and resident burrowing owls in Arizona

et al. 2022

Given the rapid pace of urbanization, mitigation translocations are increasingly being used to reduce human-wildlife conflicts, especially to move animals out of the path of land development. Burrowing owls (Athene cunicularia) are commonly subjected to translocations because of their association with flat, open lands that are attractive to development. But outcomes of burrowing owl translocations and the effects they have on their demographic parameters are seldom documented. From 2017-2019, we tracked the fates of 42 resident (non-translocated) burrowing owls and 43 translocated owls using very high frequency radio-telemetry across 4 release sites in southcentral Arizona, USA. Translocations were conducted by Wild At Heart (WAH), a non-profit raptor rehabilitation program, and owls were moved from areas withplanned development activities to release sites that contained artificial burrows. Each year, WAH held translocated owls in groups of 6-10 owls with varying male to female ratios in aviaries prior to taking the owls to release sites where the owls stayed in soft-release tents for an acclimation period of 30 days before release. Resident owls were located at or near the 4 release sites. We used the joint live encounter and dead recovery model to evaluate differences in survival and fidelity probabilities between resident (non-translocated) and translocated burrowing owls and to assess factors that influenced these probabilities including sex, year, site, captivity duration, and the number of males in release cohorts for translocated owls. Annual survival was consistently lower for translocated
