However, in 2009, Price, Lanyon, and Omland conducted a study that shows that both males and females of many tropical orioles sing. This has been substantiated by 2016 documentation of female song in Puerto Rican orioles by Campbell et al., proving that song is not a method of communication solely possessed by males. The research theorizes that the prevalence of female song correlates to a tropical lifestyle wherein there is increased female-female competition and territory defense that necessitates such communication. Additionally, ancestral state reconstruction of the Caribbean oriole clade shows that female song is an ancestral trait.

The eggs are white with a bluish hue with light lavender-gray-brown speckles and spots. The nests are structured as a basket made from woven fibers of palm material, and are usually suspended from the underside of a palm leaf by two points. One threat to oriole nesting is parasitism by the
