Summary: 

In this paper the authors tackle the question of which host variables (phylogenetic, seasonal, or host-pathogen-specific) affect parasite prevalence  and specialization in various species of bird.  

Overview:

This study used an impressive number of individuals from over a nine year period to address an interesting question that can have implications not only in ecology but also in human health and how it will interact with climate change. However, some of the participants found the narrative a bit confusing and thought a clearer description of the objectives in the introduction would be helpful. Additional clarification was also requested in the methods. In particular, the molecular methods were not clear particularly on how new lineages were determined with the PCR approach and how the authors dealt with co-infections.
