Philornis parasitism: impact on nestlings and risk factors involved

Carlos Biagolini-Jr. & Regina H. Macedo
Parasitic botfly larvae (Philornis ssp., Diptera: Muscidae) are found in nests of several bird taxa, although prevalence and nestling tolerance vary considerably among species. Here we describe patterns of botfly infestation in blue-black grassquit (Volatinia jacarina) nestlings. We identified the most typically affected nestling body parts and assessed parasite prevalence, impact on nestling survival, changes in nestling body shape and mass index. Additionally, we tested whether climatic conditions, nest morphology and habitat characteristics are associated...
