“…na família sulidae, as publicações baseadas em observações ecológicas apontaram para a ocorrência de CeP e bigamia (osório-Beristain & drummond 1998, Castillo-Guerrero et al 2005, enquanto que os estudos genéticos evidenciaram monogamia (Baumgarten et al 2001, anderson & Borg 2006). a ocorrência de monogamia nesta família é interessante, pois espécies dessa família apresentam níveis altos de cuidado parental, tanto na fase de incubação quanto durante o crescimento dos filhotes (Martins & Dias Filho 2003). o cuidado parental é um caráter geralmente presente nas aves monogâmicas, mas não pode ser considerado como explicação universal para a evolução da monogamia porque nem toda espécie monogâmica apresenta cuidado parental (dunbar 1995).…”

RESUMOUma revisão sobre sistemas de acasalamento e aspectos gerais da biologia reprodutiva em aves aquáticas neotropicais foi desenvolvida para avaliar o conjunto de publicações na literatura e nortear estudos futuros nesse grupo. Foram analisados 34 artigos científicos, classificados em dois temas principais: "sistemas de acasalamento" (10) e "biologia reprodutiva" (24). sistemas de acasalamento foram estudados em nove espécies de aves neotropicais, pertencentes a quatro famílias: anatidae, diomedeidae, sulidae e threskiornithidae. em 56% das espécies foram reportadas cópulas e/ou fertilização extra-par, em 22% monogamia, em 11% bigamia e em 11% parasitismo de ninho. dados gerais de biologia reprodutiva foram levantados em 30 espécies neotropicais, sendo 20 de aves marinhas e 10 de aves lacustres. os três enfoques mais comuns encontrados nesses estudos foram cronologia reprodutiva (73% das espécies), tamanho das ninhadas em número de ovos (80%) e sucesso reprodutivo avaliado pelo número de ovos eclodidos (73%). apenas uma espécie da família sulidae (Sula leucogaster) e uma da threskiornithidae (Eudocimus ruber) foram estudadas sob os dois enfoques. Uma análise conjunta dos dados levantados revelou que as aves marinhas e os Ciconiiformes têm sido extensivamente estudados quanto às características reprodutivas gerais, porém seus sistemas de acasalamento não foram ainda bem investigados. Palavras-chave: acasalamento, aves aquáticas, comportamento reprodutivo, neotropical. ABSTRACTMATING SYSTEMS AND REPRODUCTIVE BIOLOGY OF NEOTROPICAL WATERBIRDS. the present paper reviews the published information on the mating systems and reproductive biology of Neotropical waterbirds. Thirty-four scientific articles were included, which were divided into two main themes: "mating systems" (10 articles) and "reproductive biology" (24 articles). extra-pair copulation and/ or fertilization were reported to occur in 60% of the neotropical species investigated, while monogamy was reported in 22%, bigamy in 11% and nest parasitism in 11%. General aspects of reproductive biology of 30 species were more extensively reviewed, of which 20 were seabirds and 10 were lacustrine species. aspects most frequently described were reproductive chronology (73% of species), clutch size (80%) and reproductive success defined by the number of hatched eggs (73%). Only one species in Sulidae (Sula leucogaster) and one in threskiornithidae (Eudocimus rubber) were studied for both, mating system and reproduction. a global analysis of the available data revealed that seabirds and Ciconiiformes birds were most intensively studied in terms of reproductive biology, while their mating systems remain largely uninvestigated.

“…En los bobos cafés de Morros El Potosí, las hembras incubaron durante más tiempo que los machos, similar a lo reportado para las islas de la costa brasileña (Martins y Dias, 2003) e Isla San Jorge, en 2004(Suazo-Guillén, 2004. En cuanto al cuidado de nidos con pollos, los bobos patas azules de Isla Isabel mostraron pocas diferencias entre sexos en el tiempo dedicado al cuidado y protección de los pollos (Guerra y Drummond, 1995), igual que la misma especie anidando en Isla El Rancho (J.A.…”

Resumen. 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 fl uctuaciones de corta duración en la disponibilidad de alimento durante el periodo de estudio. Palabras clave: éxito reproductivo, buceo, viajes de forrajeo, cuidado parental.

“…Behavioral observations were initiated during the later stages of the species' breeding period, which typically starts in March and April (Schulz-Neto 2004). The approximate ages of individual Red-footed Booby fledglings were estimated based on the known patterns of plumage development in the species, according to Martins & Dias (2003). We observed 15 nests, in the canopy of trees close by about seven meters from the ground and an average distance of 10 m from the observer.…”

WHEN THE FLEDGLINGS RED-FOOTED BOOBIES (Sula sula) ACQUIRE FLIGHT CAPACITY

The high cost of parental care may sometimes result in a conflict of interest between parents and offspring. To achieve the benefits of producing viable offspring and/or additional breeding opportunities, tropical seabirds must be able to afford the costs of searching for food in an oligotrophic environment. In order to verify the behavioral variation of Red-footed Boobies (Sula sula) during the late phase of its development, over a 12 week period was recorded the behavior of 15 fledglings. The behavioral records were made with the instantaneous focal animal method in windows of 15 minutes and records every minute. Records of feeding, agonism and frigates attacks were recorded ad libitum during the days of observation. No differences in the frequency of activities displayed by offspring at advanced stages of fledgling development, or in the frequency of parental presence during the transitional period to full capacity for flight were detected. On the other hand, it was observed that fledglings synchronized their presence at the nest with that of the adults even after achieving full flight capacity and that during periods of absence neighboring offspring were likely to occupy vacant nests. We speculate that with this behavior they apparently are trying to acquire, opportunistically, extra food resources from other, not directly related adults. However, we did not observe any fledgling being fed by a non-related adult. We also recorded the expression of aggressive behaviors of a fledgling towards a neighboring fledgling on the nest. These observations suggest the presence of a behavioral strategy in this species that is motivated by the continuously high demand for sustenance as the frequency of parental provisioning declines during the more advanced stages of offspring development. Although we did not verify changes in the fledglings' behavioral repertoire, the occurrence of agonistic behavior among them suggests that they must try alternative strategies to get food while not quite ready to live independently.
