The source of literature I choose is The Birds of British Columbia Volume 4 by Robert Campbell et al. This source is a great starting point for my project as it has a broad scope and will help me narrow down my subject to formulate an initial hypothesis.
This is an Academic Peer Reviewed source as it academic authors, appendices, references cited and was published by the University of British Columbia.
