Abstract
Interspecies interactions are strong drivers of natural selection, but their combined effects in nature are poorly understood. Here I investigate the breeding ecology of wild populations of Carolina Wrens and Prothonotary Warblers – species breeding in sympatry and occupying similar ecological niches but with contrasting life-histories. Wrens are, for example, noisy and aggressive when defending their nests and territories from potential threats and are far less likely than warblers to experience brood parasitism but more likely to experience nest depredation, especially when the density of nesting pairs increases. I hypothesize that the migratory warblers derive a fitness benefit from nesting closer to wrens through a reduction in nest depredation and parasitism. This thesis investigates (i) how these species are interacting with each other in space and time in the context of brood parasitism and nest depredation, and (ii) the potential contribution of habitat fragmentation in shaping these interactions.
