Hematocrit, estimated total plasma solids, total and differential white cell counts, serum glucose, calcium, phosphorus, uric acid, total protein, albumin, globulin, aspartate aminotransferase, and creatinine phosphokinase were analyzed. Hematologic and serum chemis...
متن کاملHybridization from Possible Sexual Mis-imprinting: Molecular Characterization of Hybridization between Brown Sula Leucogaster and Blue-footed Boobies S. Nebouxii
Approximately 9.2% of avian taxa are known to hybridize, a larger proportion than most vertebrate groups. However, rates of hybridization vary widely across avian orders: ducks and geese (Anseriformes) hybridize widely and frequently, while hybridization between swift species (Apodiformes) has never been recorded (Grant & Grant 1992). Seabirds, excluding the whiteheaded gull complex (Charadriif...
متن کاملMale preference for female foot colour in the socially monogamous blue-footed booby, Sula nebouxii
Female ornaments are expected to evolve through sexual selection when male parental investment is high. Blue-footed boobies are socially monogamous seabirds with a long period of biparental care. Males and females have colourful feet that are displayed ostentatiously during courtship, both before and after pairing, and extrapair copulations are frequent. We manipulated the foot colour of paired...

متن کاملDevelopment of flight performance in the brown booby.
How do birds acquire flight skills after fledging? This issue is important, as it is closely related to variation in the duration of offspring care, the causes of which remain unknown. In this study, we raised hatchling brown boobies, Sula leucogaster, and attached an acceleration data logger to each bird at fledging to record its movements. This allowed us to quantify precisely the time spent ...
