Arthropod ectoparasites such as botflies in the genus Philornis can have a highly detrimental effect on survival of nestlings of many bird species in the Neotropics (Dudaniec and Kleindorfer 2006) including small Falconiformes (Delannoy and Cruz 1991).
Twenty-nine of 35 nestlings that could be inspected (n = 15 nests) were infested with subcutaneous botflies (Philornis sp.
15-20 mins), or when all chicks died mainly as a result of parasitism by botflies (Philornis seguyi; Segura and Reboreda 2011).
Supposedly the cowbird chicks would pick parasitic botflies off the rightful nestlings.
