description It has been proposed that nestling manipulation by researchers or bird ringers may precipitate fledging. premature fledging of broods may have deleterious effects on fledgling survival due to their limited flying ability during their first days out of the nest, during which drastic falls in offspring survival have been observed. thus it is important to ascertain whether early fledging may be an unwelcome outcome of standard ringing and measurement procedures. this was tested by field experiment during two breeding seasons on a Spanish population of nest-box breeding pied flycatchers Ficedula hypoleuca. three levels of disturbance were randomly assigned to nests: 1) maximum disturbance, where nestlings were ringed at seven days old and measured and weighed at 13 days old, and nest-boxes were opened daily to ascertain nestling presence from day 15 until the whole brood fledged; 2) medium disturbance, with similar handling and measurement procedures but without nest-box checks after day 15, and 3) minor disturbance, where nestlings were ringed on day seven but were not handled after that age and no nest-box checks were conducted after day 15. whole-brood fledging age, (at 18 days on average), for the two reduced disturbance treatments was ascertained through daily observation of parental activity near the nest-box, with subsequent checks of nest-boxes when no activity was detected. No effect of disturbance on fledging age was found, controlling for year. the only factors clearly linked to early fledging were hatching date (late broods fledged at earlier ages) and the presence of ectoparasitic mites Dermanyssu gallinae (infested broods fledged earlier). No significant harmful effects of standard nestling manipulation or nest-check procedures were thus detected.—Moreno, J. (2025).

Ardeola, 72: 329-337.la manipulación de pollos en el nido por investigadores o anilladores puede precipitar el abandono del mismo. El abandono prematuro del nido podría tener efectos deletéreos sobre la supervivencia de los volantones debido a reducidas capacidades de vuelo durante los primeros días fuera del nido, cuando se ha observado importante mortalidad. Es relevante establecer si un adelanto en el abandono del nido es un resultado esperable de procedimientos habituales de medición y marcaje de pollos nidícolas. En este estudio, realicé un experimento de campo durante dos años en una población española de papamoscas cerrojillo Ficedula hypoleuca que cría en nidales. Se asignaron al azar tres niveles de molestias en el nido: 1) molestia máxima, en que se anillaron los pollos con 7 días y se midieron y pesaron con 13 días, controlándose la presencia de pollos en el nido a partir del día 15 mediante apertura del nidal; 2) molestia media, con la misma manipulación que en el caso anterior, pero sin controles mediante apertura del nidal, y 3) molestia menor, en que se anillaron los pollos el día 7 pero no se midieron el día 13 ni se realizaron controles a partir del día 15. la edad de abandono de toda la nidada para los dos tratamientos de menor molestia (promedio 18 días) fue determinada mediante observación diaria a distancia de la actividad parental junto al nidal, con controles inmediatos del mismo cuando no se detectaba actividad. No se encontró ningún efecto del tratamiento experimental sobre la edad de abandono controlando por año. los únicos factores claramente relacionados con abandono temprano fueron la fecha de eclosión (nidadas tardías abandonan a edades más tempranas) y la presencia en el nido de ácaros Dermanyssu gallinae (nidadas infestadas abandonan antes). En conclusión, no se detectaron efectos significativos de procedimientos estándar de manipulación de pollos o control de nidos.—Moreno, J. (2025). la manipulación estándar de pollos por investigadores no afecta a la edad de abandono del nido: un experimento de campo en papamoscas cerrojillo Ficedula hypoleuca.
