- Certhiola. In these pretty little American creepers the sexes are alike, and they build a domed nest.
- Mynahs (Sturnidæ). These showy Eastern starlings have the sexes exactly alike. They build in holes of trees.
- Calornis (Sturnidæ). These brilliant metallic starlings have no sexual differences. They build a pensile covered nest.
