Song as an aggressive signal in songbirds (2009, methodology): “Finally, in studies of eastern song sparrows (Searcy et al. 2006) and swamp sparrows,Melospiza georgiana (Ballentine et al. 2008), in which subjects were presented with a taxidermic mount of a conspecific, type matching failed to predict whether a subject would subsequently attack the mount.”
Low-amplitude song predicts attack in a North American wood warbler (2010, methodology): “An attack was defined as when a focal birdmade direct contact with themount, or made a direct flight or dive to within 1 m of the mount (Ballentine et al. 2008).”
The central importance of information in studies of animal communication. (2010, background): “In hermit crabs, Pagurus bernhardus (Laidre 2009), swamp sparrows, Melospiza georgiana (Ballentine et al. 2008), and banded wrens, Pheugopedius pleurostictus (Vehrencamp et al. 2007), certain visual or vocal displays are reliable predictors of an individual’s subsequent aggressive behaviour, and…”
Soft Song in Song Sparrows: Acoustic Structure and Implications for Signal Function (2008, background): “One explanation for the use of multiple categories of soft song by the birds is that the categories differ in the level of threat that they convey, but preliminary evidence does not support this hypothesis, at least not for swamp sparrows (Ballentine et al. 2008).”
