Oriolus
Genetic analyses of specimens with aberrant plumage revealed hybridization between Olive-backed Oriole (O. sagittatus) and Green Oriole (O. flavocinctus) in New Guinea (Joseph et al., 2019).

Pitohui
A genetic study found evidence for introgression between Hooded Pitohui (P. dichrous) and Southern Variable Pitohui (P. uropygialis). This genetic exchange might explain the similar plumage patterns and toxicity (these birds are poisonous due to batrachotoxins in their feathers and skins) of these species (Garg et al., 2019)
