“…The oldest recorded free‐living individual of this species lived to an age of 41 years (Marchant & Higgins 1993). These limited data suggest that southern temperate Charadrius species are considerably longer‐lived than their northern temperate counterparts, whose annual adult survival estimates range between 51 and 79% (Table 2), with the oldest known individual living to an age of 15 years (Page et al . 1995).…”

“…We found most nests by observing courting and incubating adults. Nest age was determined by observing dates of clutch completion, back‐dating 31 days from the date of hatch (Page et al. 1995), or floating completed clutches (Alberico 1995).…”

Predation is an important cause of nest failure for many birds and has shaped the life‐history characteristics of many species, especially ground‐nesting shorebirds. We examined nesting success, causes of clutch failure and nest survival in relation to variation in substrate characteristics in a colour‐marked population of Western Snowy Plovers Charadrius alexandrinus nivosus breeding on riverine gravel bars in coastal northern California. Plovers experienced higher nesting success on gravel bars than on nearby beaches, which were characterized by more homogeneous, sandy substrates. On gravel bars, Plovers nested in habitats characterized by large, heterogeneous substrates, with more egg‐sized stones, compared with random sites. Egg crypsis, as indexed by time required of a naïve observer to detect a nest, increased with number of egg‐sized substrates. Nest survival correlated negatively with heterogeneity of substrates and positively with the number of egg‐sized stones. Consistently high nesting success of Plovers on gravel bars indicates that this high‐quality habitat deserves special management considerations given the species’ threatened status.

“…Ravens also have been implicated in suppressing reproduction in other species of conservation concern, preying on newly hatched desert tortoises (Gopherus agassizii; Boarman 1992) and consuming clutches or young of marbled murrelets (Brachyramphus marmoratus; Singer et al 1991), least terns (Sterna antililarum; Avery et al 1995), and western snowy plovers (Charadrius alexandrinus nivosus; Page et al 2009). Nest predation can reduce prey populations substantially (Garrott et al 1993, Schneider 2001.…”

Landscape characteristics and livestock presence influence common ravens: relevance to greater sage‐grouse conservation

et al. 2016

Common raven (Corvus corax; hereafter, raven) population abundance in the sagebrush steppe of the American West has increased threefold during the previous four decades, largely as a result of unintended resource subsidies from human land‐use practices. This is concerning because ravens frequently depredate nests of species of conservation concern, such as greater sage‐grouse (Centrocercus urophasianus; hereafter, sage‐grouse). Grazing by livestock in sagebrush ecosystems is common practice on most public lands, but associations between livestock and ravens are poorly understood. The primary objective of this study was to identify the effects of livestock on raven occurrence while accounting for landscape characteristics within human‐altered sagebrush steppe habitat, particularly in areas occupied by breeding sage‐grouse. Using data from southeastern Idaho collected during spring and summer across 3 yr, we modeled raven occurrence as a function of the presence of livestock while accounting for multiple landscape covariates, including land cover features, topographical features, and proximity to sage‐grouse lek sites (breeding grounds), as well as site‐level anthropogenic features. While accounting for landscape characteristics, we found that the odds of raven occurrence increased 45.8% in areas where livestock were present. In addition, ravens selected areas near sage‐grouse leks, with the odds of occurrence decreasing 8.9% for every 1‐km distance, increase away from the lek. We did not find an association between livestock use and distance to lek. We also found that ravens selected sites with relatively lower elevation containing increased amounts of cropland, wet meadow, and urbanization. Limiting raven access to key anthropogenic subsidies and spatially segregating livestock from sage‐grouse breeding areas would likely reduce exposure of predatory ravens to sage‐grouse nests and chicks.
