Exposure to Heavy Metals in American Robins: Impacts and Implications
American robins are a common bird in a variety of habitat types across North America, such that they have the potential to serve as excellent bioindicators of environmental contamination in a variety of settings. We build on previous work to develop analytical techniques such as ICP-MS and XRF for …

Reproductive Decisions in American Robins (Turdus Migratorius): Relationships Among Paternity Allocation, Parental Care, Plumage Variation, and Mate Choice
… songbird. Reproductive success in American robins was strongly influenced by the number of nesting attempts made in a single breeding season and the likelihood of making multiple nesting attempts was associated with initial nesting success and the timing of breeding onset. EPP was common, …

Impacts of host biology on the urban eco-epidemiology of West Nile virus
… American robin (Turdus migratorius, hereafter robins), and results in decreased individual risk of West Nile virus exposure for social individuals compared to non-social birds. Using sentinel birds, I determined that birds which did not participate in communal roosts had higher risk of exposure …

The value of animal behaviour as a bio-indicator of restoration quality
… support a resident population of red-capped robins Petroica goodenovii, which was the focal species of this study. The robins are typically groundforaging insectivores that generally have been found to respond negatively to anthropocentric land use changes. The suitability of the Island’s …

Incubation temperature impacts growth, physiology and survival in nestlings of an open-cup nesting passerine
… key aspects of nestling development in American robins (Turdus migratorius). Specifically, I sought to address whether incubation temperature influences (1) hatching success, (2) nestling growth rate and three key morphological characteristics, (3) development of the …

Female Ornamentation in the American Robin
… care and variable female ornamentation. Female robins display conspicuous red breast plumage, bright yellow bills, and achromatic ornamentation. Female ornamentation is similar to males, but is subdued to varying degrees across individuals. Female colouration could function as a useful criterion …

The Role of Urban Climate and Land Cover in Phenology, Nest Success, and Habitat Use
… impacted nest survival rates of American Robins (Turdus migratorius), Mourning Dove (Zenaida macroura), and Black-headed Grosbeaks (Pheucticus melanocephalus). Nest survival increased at warmer than normal temperatures and to a lesser extent at colder than normal temperatures. Canopy cover …
