          Abstract

          Resumen: Tanto factores bióticos como abióticos se han resaltado como negativos para el éxito de la anidación en las aves, destacando entre ellos la depredación, fenómenos naturales y enfermedades emergentes. Sin embargo, las aves también suelen ser muy susceptibles a los endo- y ectoparásitos. Los dípteros son los parásitos más comunes, y se encuentran las familias Calliphoridae, Muscidae y Piophilidae. El género Philornis (Muscidae) está estrechamente relacionado con las aves, causando un impacto negativo en las nidadas y en el desarrollo de los pichones. En colibríes se ha reportado la presencia de Philornis en Glaucis hirsuta, Thalurania glaucopis y Eupetomena macroura. En nuestro estudio reportamos la presencia de Philornis bellus en pollos de Amazilia rutila, Cynanthus latirostris y Chlorostilbon auriceps en una selva baja. Cynanthus latirostris presentó el mayor número de larvas y A. rutila presentó menor número. Aunque se ha afirmado que un número mayor de 7 larvas resulta letal, para hacer tal aseveración es necesario hacer estudios experimentales, así como considerar un monitoreo sistemático en mayor número de nidos para determinar el efecto a nivel poblacional de estos parásitos.

          Abstract: Both biotic and abiotic factors have been highlighted as negative for nesting success in birds, including predation, natural phenomena and emerging diseases. However, birds are also susceptible to endo- and ectoparasites. Diptera are the most common parasites, being families as Calliphoridae, Muscidae and Piophilidae the more reported as bird parasites. The genus Philornis (Muscidae) is closely related to birds, causing a negative impact on nestlings and their development. In hummingbirds the presence of Philornis has been reported in nestlings of Glaucis hirsuta, Thalurania glaucopis and Eupetomena macroura. In this study, we recorded the presence of Philornis bellus in nestlings of Amazilia rutila, Cynanthus latirostris, and Chlorostilbon auriceps in a tropical dry forest. Cynanthus latirostris presented the highest larvae number and A. rutila the lowest. Although it has been affirmed that more than 7 larvae are lethal for birds, it is necessary to conduct experimental studies and to consider a systematic monitoring of nests to determine the population-level effects of these parasites.
