dc.description.abstract | Abstract- Aspects of the breeding biology of the Yellow Warbler (Dendroica petechia) and Shiny Cowbird (Molothrus bonariensis) parasitism were studied in Boquerón, Puerto Rico from 2001 to 2002. Fifty-seven percent (n = 12) of warbler nests were parasitized. Survival of parasitized nests was lower than non-parasitized nests. Thirty-four percent of nests (n = 21) survived until fledging of cowbird or warbler chicks, with predation the major cause of nest failure (88%). Nineteen nests fledged warbler young and two nests fledged cowbird young, but no nest fledged warbler and cowbird young simultaneously. The Yellow Warbler presented three responses toward parasitism: acceptance and incubation, egg burial, and nest desertion. No warbler young fledged from nests that accepted parasitism. Nests with buried cowbird eggs fledged an average of 2.00 ± 1.41 warbler chicks. This study shows that the Yellow Warbler in Puerto Rico expressed anti-parasite strategies three decades after first contact with the Shiny Cowbird. | en_US |
dc.description.abstract | Resumen- Se estudiaron aspectos de la biología reproductiva del Canario de Mangle (Dendroica petechia) y del parasitismo del Tordo Lustroso (Molothrus bonariensis) en Boquerón, Puerto Rico, desde 2001 hasta 2002. Cincuenta y siete porciento (n = 12) de los nidos de canario fueron parasitados. La supervivencia de los nidos parasitados fue menor que la de los nidos no parasitados. Treinta y cuatro porciento (n = 21) de los nidos sobrevivió hasta que volaron pichones de tordo o canario, siendo la depredación la principal causa de pérdidas de nidos (88%). Juveniles de canario volaron de 19 nidos y juveniles de tordo volaron de dos nidos, pero de ningún nido volaron juveniles de canario y de tordo simultáneamente. El Canario de Mangle presentó tres respuestas al parasitismo: aceptación e incubación, enterramiento de huevos y abandono del nido. Ningún juvenil de canario voló de nidos que aceptaron el parasitismo. Los nidos con huevos de tordo enterrados volaron un promedio de 2.00 ± 1.41 juveniles de canario. Este estudio muestra que el Canario de Mangle en Puerto Rico expresó estrategias antiparásitas luego de tres décadas del primer contacto con el Tordo Lustroso. | en_US |
