“…While winter home range values for inland curlews have been documented (Sesser 2013, Kerstupp et al 2015 and fall approximately within the range that we report here, this study is the first to report home range size for coastal, non-breeding curlews. Curlews wintering in inland areas utilized much larger home ranges and showed more movement throughout the non-breeding season, presumably tracking patchy resources on agricultural lands, whereas coastal-wintering birds were apparently able to meet energetic requirements in relatively small home ranges.…”

“…The outlined conservation actions fall into four groups: 1) population monitoring and assessment; 2) habitat assessment and management; 3) research; and 4) education and outreach. Since the publication of the plan, curlew research has filled existing gaps in each of these categories, especially with regards to assessing nesting success and breeding habitat in areas where information was lacking (Hartman and Oring 2009, Gregory et al 2011, tracking migratory routes (Page et al 2014), mapping wintering range and habitat (Sesser 2013, Page et al 2014, Kerstupp et al 2015 and studying wintering ecology (Navedo et al 2012, Shurford et al 2013, Kerstupp et al 2015. Our research addressed several of the identified knowledge gaps, but also added components beyond the scope of the plan.…”

“…Inland areas have been modified from historical habitats, but irrigated agricultural fields may provide a functional equivalent for lost wetland habitats (Elphick 2000), and a wealth of research indicates these substitute habitats play an important role for wintering curlews (Dugger and Dugger 2002, Shuford et al 2013, Sesser 2013, Kerstupp et al 2015. For example, in the southeastern Chihauhuan desert, Kerstupp et al (2015) found tagged curlews in agriculture and fallow fields 50% of the time, and in the Central Valley, curlews were highly associated with irrigated alfalfa and irrigated pasture (Shuford et al 2013, Sesser 2013.…”

“…As such, nonbreeding season research to date has incorporated the use of satellite transmitters to track curlews (Sesser 2013, Page et al 2014, Kerstupp et al 2015, on-the-ground monitoring of abundance and distribution (Colwell and Landrum 1993, Colwell 2000, Mathis et al 2006, Shuford et al 2013, or close-range observation for diet studies (Leeman et al 2001, Saalfeld et al 2010. Despite recent major advances in the knowledge of migratory connectivity of curlews from Page et.…”

Building the Full Annual Cycle Picture for Long-Billed Curlews: Correlates of Nest Success in the Breeding Grounds and Spatial Distribution and Site Fidelity in the Wintering Grounds

The following individuals read and discussed the thesis submitted by student Stephanie E. Coates, and they evaluated her presentation and response to questions during the final oral examination. They found that the student passed the final oral examination. and lower percent cover of grasses, bare ground, and shrubs than available sites. Nestsites were six times more likely to have a cowpie within 50 cm than random sites. Higher probability of nest success was associated with higher curlew density in the nesting area, increasing percent cover of conspicuous objects such as cowpies within approximately two meters of the nest, and -surprisingly -higher densities of American Crows and Black-billed Magpies in the breeding area. In a separate analysis with a subset of nests (n = 100), we found nests had higher probability of success when they were farther from roads and perches. Given the central role of working lands to breeding curlews in much of the Intermountain West, an understanding of limitations to nesting success in these diverse landscapes is necessary to guide adaptive management strategies in increasingly human-modified habitats. Similarly, foundational understanding of winter spatial ecology is essential for understanding population declines which may be related to linkages viii between breeding and non-breeding seasons. Overall, these findings provide valuable information for full annual cycle conservation and will be particularly constructive for conservation planning once range-wide migratory connectivity is mapped.
