“…Chestnut-collared Longspurs generally breed in drier, shortgrass to shortmixed-grass prairie, while Sprague's Pipits and Baird's Sparrows range across the breadth of mixed-grass prairie grassland types (Knopf 1996). Our assemblage of breeding songbirds, in addition to plant community composition and structure (Dieni and Jones 2003), classify our study area as xeric short-mixed-grass prairie (Knopf 1996, Askins et al 2007). Breeding Bird Survey data indicate long-term declines in rangewide populations for all our focal bird species (Sauer et al 2008).…”

“…Search techniques (% successful) included behavioral observations (3%) (Martin and Geupel 1993), opportunistic foot flushes (36%), and rope dragging (61%) (Davis 2003, Dieni andJones 2003). Nests were marked for relocation by placing a discrete strip of plastic flagging on the ground ,2.5 m on either side of the nest.…”

“…Total numbers of species and nesting species, and bird and nest densities among parks of different size classes were examined with a multivariate analysis of variance (MANOVA) using Pillai's trace value V, followed by a post-hoc analysis using Tukey's Honest Significant Difference (HSD) test (Zar 2010). A discriminant function analysis was applied to determine the most explanatory characteristics among species' nesting characters (Hair et al 1992;Dieni and Jones 2003).…”

Effects of area size, heterogeneity, isolation, and disturbances on urban park avifauna in a highly populated tropical city

We assessed bird diversity and nesting activity in 54 urban parks in the core of a highly populated East-Asian tropical city to investigate the effects of area, isolation, habitat heterogeneity, and human disturbances on avifauna. Tree density and heterogeneity were lower while isolation was greater in small than in large or medium-sized parks. Yet, park features were often interrelated, with isolation variables negatively correlated to each other, heterogeneity positively correlated to area, and habitat variables mostly positively correlated with one another but variously to disturbances; whereas pedestrian densities wee positively correlated with green area proportions (ISO3) but negatively with the distances to large green areas (ISO2). Park size played a primary role by positively affecting species richness and numbers of nesting species, thus contributing to higher total and nesting species heterogeneity, and determining the occurrence of a greatest number of species. Pedestrian density, canopy cover, and ground heterogeneity played secondary roles, whereas isolation appeared less influential at the community level. Omnivores, granivores, and aerial insectivores appeared more abundant but were dominated by several common species. Nesting was restricted to even fewer species. While species varied in the occupancy responses to these factors, tree heterogeneity positively affected the nesting of Zosterops japonicus and cavity-nesting birds, and predator density negatively affected those of Lonchura punctulata and Streptopelia doves. Improved urban land use planning and park management incorporating these effects should be implemented to enhance breeding and avoid compositional homogenization for long-term sustainability of urban avian diversity.

“…Previous studies have demonstrated that prairie songbirds actively select for nest site vegetation that is taller and denser than is generally available (Sutter 1997;Dieni and Jones 2003;Davis 2005). One hypothesis to explain this pattern is that birds are attempting to reduce the risk of nest predation by selecting for nest sites with greater cover, limiting the availability of visual, auditory, and olfactory cues that predators use to locate nests (Martin 1993).…”
