Title A name given to the resource Ecología reproductiva del bobo café (Sula leucogaster) en Morros El Potosí, Guerrero, México Reproductive ecology of Brown Boobies (Sula leucogaster) at Morros El Potosí, Guerrero, Mexico Creator An entity primarily responsible for making the resource Juan Pablo Ceyca, Eric Mellink Description An account of the resource Entre enero y junio de 2006 se estudió la ecología reproductiva del bobo café (Sula leucogaster) en Morros El Potosí, Guerrero. Determinamos parámetros reproductivos, profundidad máxima de buceo, duración de viajes de forrajeo y porcentaje de atención al nido. Los bobos cafés anidaron durante gran parte del año y exhibieron 2 picos reproductivos: otoño y primavera. Durante este último, el éxito de eclosión fue 61%. Estimamos densidades de 1 300 nidos/ha en la ladera y de 2 000 nidos/ha en la cima de la isla. No observamos depredación, pero condiciones meteorológicas adversas causaron pérdida de huevos y muerte de pollos. Los viajes de forrajeo más largos (5.78 ± 0.21 h) y los buceos más profundos (5.52 ± 0.42 m) en Morros El Potosí que en otras colonias, sugirieron que los bobos cafés requirieron aquí un mayor esfuerzo de forrajeo, quizás por estar en aguas más calientes, con menos recursos. Los bobos cafés hembra atendieron por más tiempo los nidos con huevos o con pollos que los machos. No hubo diferencias en el tiempo de presencia de los padres en el nido entre meses, lo que, aunado a la variación en la duración de los viajes de forrajeo entre meses, sugiere que hubo fluctuaciones de corta duración en la disponibilidad de alimento durante el periodo de estudio.We studied the breeding ecology of Brown Boobies (Sula leucogaster) at Morros El Potosí, Guerrero, between January and June 2006. We determined breeding parameters, foraging habits, and patterns of parental care, and evaluated their effects upon breeding success. Brown Boobies nested during a great part of the year, and exhibited 2 breeding peaks: Fall and Spring. During the later, hatching success was 61%. We estimated 1 300 nests/ha on the slope of the island, and 2 000 nests/ha on the top. We did not record predation, but adverse meteorological conditions caused the loss of eggs and chicks. The longer foraging trips (5.78 ± 0.21 h) and deeper diving (5.52 ± 0.42 m) at Morros El Potosí than at other locations suggested that they required a larger foraging effort here, maybe due to warmer water with less resources. Female Brown Boobies spent more time than males tending nests with eggs, or chicks. There were no differences in parental care of the nest among months, which along with variations in the length of foraging trips among months suggests that there were short-term fluctuations in food availability throughout the study.
