Abstract:Entanglement and mortality of Palila (Loxioides bailleui), an endangered Hawaiian honeycreeper, occurred when birds were radio-tagged with transmitters equipped with a long, limp, solder-tipped antenna. Birds were found suspended in trees by their transmitter antenna on eight occasions. Although these birds eventually freed themselves or were freed by us, at least one bird died afterwards. For radio telemetry studies of small passerine species we recommend avoiding transmitters equipped with an antenna that is bulbous at the tip, >16 cm in length, limp, and shiny. /// En estudio de radiotelemetría que se llevó a cabo en Loxiodes bailleui se encontraron aves enredadas y una que murió. En ocho ocasiones se encontraron aves suspendidas en la vegetación atadas a esta por la larga antena con punta en forma de bulbo. Aunque algunas aves lograron liberarse y otras fueron liberadas por el grupo de trabajo, al menos una murió. Para el estudio de pequeños paserinos, utilizando radiotelemetría, no recomendamos el utilizar antenas brillantes de >16 cm de largo, con punta en forma de bulbo.
