“…Predominately open areas (\15 % vegetation coverage) at SAK and at other breeding areas likely provide sufficient cover from predators, yet a more detailed study of predation pressure and brood survival could provide more insight into how broods use habitat features to elude predation. The movement of broods from nesting habitat to different brood-rearing habitat has been documented in a number of precocial species (e.g., Miller 1979;Talent et al 1982;Gauthier 1987;Pehrsson and Nyström 1988;Blomqvist and Johansson 1995;Loegering and Fraser 1995;Dreitz 2009;Wilson and Colwell 2010). It is thought that this movement is motivated by differing habitat needs of nesting and brood rearing (Blomqvist and Johansson 1995).…”

“…A clear example of this is upland nesting waterfowl that move their broods from grasslands to wetlands. However, differences in nesting habitat and brood-rearing habitat may be more subtle in some species, and these movements may improve brood survival (Talent et al 1982;Kosztolányi et al 2007;Lengyel 2007;Wilson and Colwell 2010). Movement comes at a cost-primarily in the form of energy expenditures and increased predation risk directly related to the movement and secondarily by increased stress of traveling through marginal, unfamiliar habitat where food resources and the danger evasion strategies needed are less well known (Rotella and Ratti 1992;Pearse et al 2004).…”

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

et al. 2015

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.

“…Next, we averaged data across the years in which an individual bred to obtain an index of corvid and human activity. We used 500 m to summarize these data because this is the scale at which observers conducted point counts ; plover chicks move an average of 500 m from their nests during the first 3 days after hatch (Wilson and Colwell 2010). Therefore, we used this as an estimate of the amount of human and corvid activity that broods encountered when they are most vulnerable (Colwell et al 2007).…”

“…Indeed, ontogenetic studies in the field present formidable technical challenges because shorebirds are highly mobile and many species inhabit open habitats. Newly hatched chicks can travel over long distances (up to a kilometer daily) while being led by their parents to feeding areas (e.g., Miller 1985;Wilson and Colwell 2010). At fledging, when flight becomes possible, home range size increases substantially as independent juveniles visit several feeding areas daily to build up energy in preparation for autumn migration (Adret 1984;Miller 1985).…”

During the breeding season, Pied Avocets, Recurvirostra avosetta, produce five morphologically distinct syllables-chuck, chirp, whistle, coo and snarlwhich form the basis of the species' adult vocal repertoire. Chuck, chirp and whistle each contribute to several call types distinguished by the temporal arrangement of the syllables that make them up, whereas coo and snarl are monosyllabic calls. Here, I document the ontogeny of these five syllables up to 11 months of age in birds reared from the egg. Sonagraphic analysis, together with the behavioral context in which the calls were uttered, suggests that both chuck and chirp syllables develop gradually from prenatal vocalizations, whereas snarl and coo syllables emerged de novo at 8 and 12 weeks of age, respectively, with the coo developing earlier in males than in females. Interestingly, the captive birds failed to develop the whistle, raising the possibility that social interactions with adults may be necessary for its production. After the breaking of the voice, which occurs at 9 months of age, syllable morphology closely resembled that of adults in the wild. This study enabled me to elaborate a synthetic tree of call development in Pied Avocets, which suggests working hypotheses to account for the unfolding of the species' call repertoire.
