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 among localities. Our results showed, however, that infection status was associated with a higher song rate, and that males and females belonging to the same reproductive pair had a strong positive correlation in infection status and parasite load.
