Effects of Back-Mounted Radio Packages on Breeding Wood Ducks (Efecto de Radiotransmisores Montados en la Espalda, en la Reproducción de Aix sponsa)
The effects of back-mounted radio transmitters on reproductive effort and return rates of pre-nesting pairs and incubating female Wood Ducks (Aix sponsa) were investigated. Twenty of 22 pre-nesting pairs remained together after capture and radio-marking, but only two females from radio-marked pairs...

description | The effects of back-mounted radio transmitters on reproductive effort and return rates of pre-nesting pairs and incubating female Wood Ducks (Aix sponsa) were investigated. Twenty of 22 pre-nesting pairs remained together after capture and radio-marking, but only two females from radio-marked pairs attempted to incubate, and none were captured in nest boxes during the subsequent 2-3 breeding seasons. Nest success, duckling survival and return rates did not differ significantly between a sample of females radio-marked during incubation and those leg-banded only, but statistical power was low (0.11-0.32). Detrimental effects of back-mounted radio transmitters may preclude their use in studies of pre-nesting Wood Duck pairs, but back-mounted transmitters appear to have minimal effects on incubating and brood-rearing females. /// Se estudió el efecto de radiotransmisores montados en la espalda en el esfuerzo reproductivo y tasa de regreso de parejas por anidar y hembras incubando de Aix sponsa. Un total de 22 parejas de patos que estaban por anidar permanecieron unidos luego de ser capturados y equipados con radiotransmisores, pero sólo dos hembras intentaron incubar, y ninguna fue capturada en cajas de anidamiento durante las 2-3 épocas de anidamiento subsiguientes. El éxito de anidamiento, supervivencia de los patitos y la tasa de regreso no se diferenció significativamente entre una muestra de hembras con radios, marcadas durante la incubación, y hembras que tan sólo fueron anilladas durante el mismo período (aunque el poder estadístico fue bajo [0.11-0.32]). Los radiotransmisores montados en las espaldas parecen tener un efecto mínimo en hembras que incuban o que crían patitos. No obstante, parecen tener un efecto detrimental en parejas por anidar. |
