Influencing habitat selection and use through conspecific attraction and supplementary feeding
… natural food sources at the release sites. Conspecific song playback as an attractant for many bird species can be used as public information about high habitat value and additionally lure birds to good food sources and nest sites. Artificial feeding stations were set up at 18 locations in …

Testing proximate causes and ultimate explanations of social cue use for habitat selection by songbirds
… whether Yellow Warblers discriminate between conspecific song categories social cues with different information about habitat quality. Second-category song broadcast attracted more Yellow Warblers to breeding habitat than first-category song did, highlighting that yellow warblers prefer to use …

Life History Divergence & Tidal Salt Marsh Adaptations of the Coastal Plain Swamp Sparrow
… selection on plumage badges, and the role of conspecific attraction in nest placement. The environmental differences of the tidal salt marsh have played strong roles in the local adaptation and divergence of coastal plain swamp sparrows from their freshwater ancestors. Many of these divergent …

Connections between individual dispersal behavior and the multi-scale distribution of a saproxylic beetle
… influenced by log size and the presence of conspecifics, although aggregation associated with conspecific attraction did not occur because emigration balanced immigration. Additionally, population growth rate showed negative density dependence in post-settlement experiments. Finally, I …

Incidence, mechanisms, and consequences of adaptive habitat selection by the dickcissel (Spiza americana)
… fitness. Other mechanisms (e.g., site fidelity, conspecific attraction, food availability, predator abundance) may thus play a stronger role in facilitating adaptive habitat selection. At the same time, I found strong evidence that vegetation altered by human activity shapes dickcissel habitat …

The nocturnal behaviors of yellow-breasted chats
Yellow-breasted Chats (Icteria virens) are a Neotropical migratory bird species that breeds in shrubland habitat in Illinois. Chats are a diurnally active species but males are known to sing often at night. This behavior suggests that chats may engage in other behaviors related to breeding at …

Manipulating social information to promote frugivory by birds on a Hawaiian island
… rates to focal plants were influenced by conspecific and/or heterospecific vocalizations. We conducted 80 playback experiments at native and introduced fruiting plants, and compared responses to silent control periods. Four times as many frugivores were detected and 10 times more frugivory …
