Rebekah Oomen, B.Sc. Honours, Trent University, 2009-2010 - Rebekah's honours thesis research examined the mitochondrial genetic structure of American white pelicans across North America using mtDNA sequencing. Her objective was to determine whether numerous perceived historic or contemporary obstacles to gene flow, such as the Pleistocene glaciations, the North American Continental Divide, and differences in migratory behaviour, were acting to cause genetic differentiation between different groups of pelicans.

Resulting paper:

Matthew Osmond, B.Sc. Honours, Queen’s University, 2007-2008 - Matt's honours thesis examined the role of female plumage colouration in the highly sexually dichromatic songbird, the American redstart. While much research has focussed on the role of the generally showier male plumage, Matt's research suggested that female plumage may also act as an indicator of individual quality in female American redstarts. 

Resulting paper:

Osmond, M.M.*, M.W. Reudink, R.R. Germain**, P.P. Marra, J.J. Nocera, P.T. Boag, and L.M. Ratcliffe. 2013. Carotenoid-based female plumage is correlated with age, reproductive behavior and mate color in the American redstart. Canadian Journal of Zoology 91: 589-595.


Ryan Germain, B.Sc. Honours, Queen’s University, 2005-2006 - Ryan's Honours thesis examined whether the bright orange plumage patches exhibited by male American redstarts signal the amount of care a male may provide to offspring. Ryan found that indeed, redstart plumage does predict parental investment and suggests that females may be using these plumage cues to assess the levels of parental care males may provide to offspring.
