Abstract
La técnica de marcaje de individuos es un procedimiento fundamental en los estudios
ecológicos de aves silvestres. En los pingüinos antárticos el uso de anillos metálicos para las aletas,
contribuyó a generar conocimientos nuevos que transformaron los conceptos básicos de su biología.
Sin embargo, en los últimos años se ha comprobado que los anillos metálicos aumentan el consumo
de energía durante la natación, pueden causar heridas y aumentar significativamente la mortalidad
de los individuos marcados. En esta nota presentamos los resultados de un experimento inicial de colocación de etiquetas electrónicas en adultos nidificantes de Pygoscelis papua, las que permiten identificar inequivocamente a los individuos marcados los que no muestran alteraciones conductuales en el proceso de nidificación. Consecuentemente el uso de estos dispositivos es una alternativa factible para el desarrollo de estudios de campo en P. papua.
The use of marked individuals is a fundamental procedure in field ecological studies of birds in the wild. The use of metal flipper bands in antarctic penguins contributed to produce new data that improved the understanding of their basic biology concepts. Notwithstanding, in recent years it has been shown that metal flipper bands can increase natural mortality and energy consumption during swiming of taged birds. In this note we report the results of the experimental use of transponders to identify adult nesting Gentoo penguins. Our results indicate that the use of transponders allows unequivocal identification of marked birds, which recover from the procedures and continue incubation and do not show behavioral perturbation after effects. We conclude that the use of these devices is a viable alternative for the development of field ecology studies in Gentoo penguins.
