To determine how taxonomic, environmental, and developmental traits relate to the prevalence of blood parasite infections in bird species.
Assessed hematozoan infection prevalence across avian families, subfamilies, habitats, and geographic zones comparing temperate and tropical species.
Analyzed associations between parasite prevalence and developmental variables—including incubation period length, body size, and postnatal growth rate—in nonraptorial altricial landbirds.
Hematozoan prevalence was inversely related to incubation period duration in nonraptorial altricial landbirds, while exhibiting little relationship to body size or postnatal development rate.
Parasite prevalence varied significantly at the family and subfamily levels rather than the genus level, with temperate species demonstrating higher infection incidence than tropical counterparts in the same families.

Implication

Comparative analysis reveals an inverse relationship between incubation period and hematozoan prevalence in landbirds, suggesting embryonic immune system maturation affects parasite resistance.
