House Sparrows Associated with Reduced Cliff Swallow Nesting Success

  title={House Sparrows Associated with Reduced Cliff Swallow Nesting Success},
  author={Douglas R. Leasure and Ragupathy Kannan and Douglas A. James},
Abstract We quantified the impact of nesting and roosting House Sparrows (Passer domesticus) on nesting success of Cliff Swallows (Petrochelidon pyrrhonota) in colonies in western Arkansas in 2007 and 2008. Two sections of a large swallow colony under a bridge with House Sparrows were compared in 2007 to two sections with little House Sparrow usage. Nesting success of Cliff Swallows (percent of nests yielding at least 1 chick) was 61% in sections with low House Sparrow activity, significantly… Expand

Examining how the prevalence of an arthropod-borne viral pathogen changes with host group size in a host-parasite system recently invaded by an introduced species that also serves as a host for the virus indicates that the presence of alternative hosts is another variable to consider in trying to predict how pathogen exposure is affected by host group sizes.

Instream Bacteria Influences from Bird Habitation of Bridges
The representativeness of ambient water samples collected from bridge crossings has occasionally been challenged because critics contend birds nesting on bridges elevate fecal indicator bacteriaExpand
Threats from introduced birds to native birds
There is little evidence that introduced birds are a major threat to avian diversity globally and the lack of evidence for detrimental effects of introduced birds on native avifauna highlights the need for future work in this area. Expand

Coloniality in the Cliff Swallow: The Effect of Group Size on Social Behavior
This study of vertebrate coloniality should be of interest to all who study social animals, including behavioural ecologists, population biologists, ornithologists and parasitologists, and should also appeal to evolutionary biologists and to psychologists studying decision making in animals. Expand
