Interspecific hybridization explains rapid gorget colour divergence in Heliodoxa hummingbirds (Aves: Trochilidae) by Chad M. Eliason, Jacob C. Cooper, Shannon J. Hackett, Erica Zahnle, Tatiana Z. Pequeño Saco, Joseph Dylan Maddox, Taylor Hains, Mark E. Hauber, John M. Bates

“…Phylogenetic comparative analysis suggests that the observed gorget coloration divergence from both parentals to this individual would take 6.6–10 My to evolve at the current rate within a single hummingbird lineage. These results emphasize the mosaic nature of hybridization and suggest that hybridization may contribute to the structural colour diversity found across hummingbirds.…”
