The chapters are definitely getting longer and more thorough. This chapter covered natural and sexual selection, speciation, hybridization, divergence of bird populations, and adaptive radiations of birds. Without going into the nitty-gritty details of the entire section, here are a few highlights that caught my attention:

While the information in the book is really useful and relevant to the bird biology course, sometimes I feel like I am gaining more value in simply learning about new species that I have never seen or heard about. For example, in the section regarding sexual selection, this photo of a nighthawk from the savannas of central Africa caught my attention:
