HYBRIDIZATION FROM POSSIBLE SEXUAL MIS-IMPRINTING: MOLECULAR CHARACTERIZATION OF HYBRIDIZATION BETWEEN BROWN SULA LEUCOGASTER AND BLUE-FOOTED BOOBIES S. NEBOUXII.

The article discusses the molecular characterization of hybridization between brown Sula leucogaster and blue-footed Boobies S. nebouxii. The researchers collected blood, feather or tissue samples from 30 brown and 15 blue-footed boobies from the Eastern Tropical Pacific. The findings of molecular sexing demonstrated that both putative hybrids were male.
