In this study, we explored the relationship between haemosporidian infection, parasite load, heterophil:lymphocyte ratio, body condition, and vocal behavior in Rufous-naped Wrens. Our results showed no evidence of an association between vocal behavior and infection status, heterophil:lymphocyte ratio, or body condition. However, we found that infection status was associated with a higher song rate and there was a strong positive correlation between infection status and parasite load in males and females belonging to the same reproductive pair.
We explored the relationship between haemosporidian infection (infected vs. uninfected), parasite load, heterophil:lymphocyte ratio, body condition and vocal behaviour of the Rufous-naped Wren Campylorhynchus rufinucha. Our results, albeit based on a small sample size, showed no evidence of an association between vocal behaviour and infection status, heterophil:lymphocyte ratio or body condition. Infections did not vary between localities. Our results showed, however, that infection status was associated with a higher song rate, and that in males and females belonging to the same reproductive pair there was a strong positive correlation in terms of infection status and parasite load.
