Radio-transmitters do not affect seasonal productivity of female Golden-winged Warblers

摘要: Investigating the potential effects of handling and marking techniques on study animals is important for correct interpretation research results to effect progress in data-collection methods. Few investigators have compared reproductive output radio-tagged non-radio-tagged songbirds, no one date has examined possible radio-tagging adult songbirds survival their fledglings. In 2011 2012, we several parameters two groups female Golden-winged Warblers (Vermivora chrysoptera) breeding Minnesota, including 45 females with radio-transmitters 73 did not capture, handle, or mark. We found difference between clutch sizes, hatching success, brood length incubation nestling stages, fledging number fledglings, fledglings independence. Thus, radio-tags had measurable impact productivity Warblers. Our build upon previous studies where reported by also demonstrating through post-fledging period and, therefore, entire season. RESUMEN Radio trasmisores afectan la productividad estacional en las hembras de Vermivora chrysoptera Investigar los efectos potenciales tecnicas manipulacion y marcaje estudios animales es importante para interpretar correctamente resultados investigaciones llevar a cabo avances metodos colecta datos. Pocos investigadores han comparado el rendimiento reproductivo aves paserinas con o sin radios trasmisores, nadie hasta fecha ha examinado posible efecto supervivencia juveniles marcadas trasmisores. En 2012 comparamos varios parametros reproductivos dos grupos chrysoptera reproduciendose cuales incluian radio 72 que capturamos, manipulamos marcamos. No encontramos diferencias entre tamano nidada, exito eclosion, numero polluelos, duracion del periodo incubacion salida polluelos nido su independencia. consecuencia, tienen un impacto apreciable V. chrysoptera. Nuestros aportan anteriores donde encontrados sobre tambien demuestra hay lo largo despues abandono nido, por ende durante toda temporada reproductiva.
