Pseudo-eggs of brown sula leucogaster andblue-footed s. nebouxii boobies in the gulf of california, mexico

Brown Booby (Sula leucogaster) Science Article 4 abstract Pseudo-eggs, foreign round objects, notably eggs of other speciesor pebbles, are common in some ground-nesting species, and havebeen reported especially in larids (Sugden 1947, Twomey 1948,Coulter 1980, Conover 1985). As many as 10% of Ring-billedGull Larus delawarensis nests in Washington, USA includedpseudo-eggs (Conover 1985). The nests of […]

Distribution of nests of the brown booby (sulaleucogaster) in relation to the inclination ofterrain

Brown Booby (Sula leucogaster) Science Article 5 abstract species of the Sulidae family, which comprisesgannets and boobies (Carboneras 1992).Brown Boobies are pan-tropical birds thatnest on a wide variety of habitats (Dorward1962a, 1962b; Skutch 1976, Nelson 1978).Brown Boobies nest on much steeper terrainthan most boobies and gannets (Nelson 1978,Carboneras 1992); for this reason, it seemsthat this […]

Weights, hematology, and serum chemistry of free-ranging brown boobies (sula leucogaster) in johnston atoll, central pacific

Brown Booby (Sula leucogaster) Science Article 13 abstract Hematologie and serum chemistry values are reported for 105 brown boobies (Sula leucogaster) from Johnston Atoll, Central Pacific. 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.

Phylogeography of Sula: the role of physical barriers to gene flowin the diversification of tropical seabirds

Brown Booby (Sula leucogaster) Science Article 11 abstract We examined mitochondrial cytochrome b sequence variation in masked Sula dactylatra,red-footed S. sula, and brown S. leucogaster boobies sampled from islands inthe central and eastern Pacific Ocean and in the Caribbean Sea. Each species showeda different phylogeographic pattern. Whereas haplotypes in masked and red-footedboobies were shared across […]

Dna fingerprinting and parentage in masked (sula dactylatra) and brown (s. leucogaster) boobies

Brown Booby (Sula leucogaster) Science Article 10 abstract Masked Booby (Sula dactylatra) and Brown Booby (S. leucogaster) are pantropical seabirds. These species are socially monogamous. Thus, males and females have a high investment in parental care. In this work, field observations and DNA fingerprinting were applied to investigate the breeding system of both species. Two […]
