“…Because our focus here was on broods, in our analyses we could only consider those broods that successfully hatched; however, in 2007 and 2008, 42 and 67 %, respectively, of nests found at SAK (n = 109 and 90 total nests) were initiated at an elevation that would become inundated before their projected hatch date (Anteau et al 2012a). Under these modified conditions, selection for nest sites near the shoreline led to increased risk of nest inundation (see also Espie et al 1996Espie et al , 1998Roche et al 2012). Our results suggest that the selection pressure for nesting at lower water elevation areas (see Anteau et al 2012b) may have been to minimize the movement distance required for broods to reach the shoreline.…”

Habitat selection and movements of Piping Plover broods suggest a tradeoff between breeding stages

In precocial birds, adults select breeding areas using cues associated with habitat characteristics that are favorable for nesting success and chick survival, but there may be tradeoffs in habitat selection between these breeding stages. Here we describe habitat selection and intra-territory movements of 53 Piping Plover (Charadrius melodus) broods (320 observations) during the 2007-2008 breeding seasons on mainland-and island-shoreline habitats at Lake Sakakawea, North Dakota, USA. We used remotely sensed habitat characteristics to separately examine habitat selection and movements at two spatiotemporal scales to account for potential confounding effects of nest-site selection on brood-rearing habitat used. The scales used were (1) the entire brood-rearing period within available brood-rearing areas and (2) 2-day observation intervals within age-specific discrete habitat selection choice sets. Analyses at both scales indicated that broods selected areas which were non-vegetated, moderately level, and nearer to the shoreline. Rate of brood movement increased with age up to 5 days, then stabilized; broods that hatched [50 m away from the shoreline moved toward the shoreline. Brood movements were greater when they were in vegetated areas, when the brood-rearing area was of greater topographic complexity, and when broods aged 6-25 days were further away from the shoreline. Using inferences from our results and those of previously published work, we postulate how a potential tradeoff in habitat selection between nesting and brood-rearing can contribute to an ecological trap in a novel habitat. This work, in the context of published works, suggests that plover breeding habitat is a complex of both nesting and brood-rearing habitats and provides a basis for making remotely sensed abundance estimates of suitable breeding habitat for Piping Plovers.

“…Ground‐nesting birds and their nests are vulnerable to a variety of threats during the breeding season, and their choices reflect complex trade‐offs (Fraser & Catlin, ). Predation often is a primary cause of nest failure (Fletcher, Aebischer, Baines, Foster, & Hoodless, ; Smith, Gilchrist, & Smith, ), and the risk of predation may change with distance to predator habitat (Espie, Brigham, & James, ) and degree of concealment (Swaisgood et al, ), which may be evidenced in avoidance or preference for vegetative cover. For birds nesting near water, inundation also can cause nest failure (Espie et al, ), and nest‐site selection may reflect a balance between predator and flood avoidance (Greenberg et al, ; Storey, Montevecchi, Andrews, & Sims, ).…”

Habitat selection and its relationship to fitness is a fundamental concept in ecology, but the mechanisms driving this connection are complex and difficult to detect. Despite the difficulties in understanding such intricate relationships, it is imperative that we study habitat selection and its relationship with fitness. We compared habitat selection of least terns (Sternula antillarum) and piping plovers (Charadrius melodus) on the Missouri River (2012–2014) to examine the consequences of those choices on nest and chick survival. We hypothesized that plovers and terns would select habitat that minimized the chance of flooding and predation of eggs, chicks, and adults, but that plovers would also select habitat that would provide foraging habitat for their chicks. We developed an integrated habitat selection model that assessed selection across multiple scales (sandbar and nest scales) and directly modeled the effect of selection on nest and chick survival. In general, the species selected habitat in keeping with our hypotheses, such that predation and flooding, in particular, may have been reduced. Sandbar selection had either a negative or no appreciable effect on nest survival for both species across years. Nest‐site selection in 2012 had a generally positive effect on nest survival and chick survival for both terns and plovers, and this trended toward a negative effect by 2014. This result suggested that early selection decisions appeared to be adaptive, but we speculate that relatively high site fidelity and habitat degradation led to reduced benefit over time. Our results highlight the complex nature of habitat selection and its relationship to fitness.

“…Previous studies have demonstrated that ground-nesting shorebirds choose nest sites in a nonrandom manner, based on factors such as substrate, vegetation cover, and conand interspecific attraction (e.g. Espie et al 1996;Cohen et al 2008). These decisions often have a significant impact on survival and reproductive success (e.g.…”
