Sexual dichromatism of the blue-throated starfrontlet, coeligena helianthea, hummingbird plumage

HIGHLIGHTS

• who: Juliana Sosa from the Biophysics, Institute Physics, University Colombia have published the article: Sexual dichromatism of the Blue-throated Starfrontlet, Coeligena helianthea, hummingbird plumage, in the Journal: (JOURNAL)
• what: We studied the optical basis of the sexual dichromatism of Coeligena helianthea, a model species for studying phenotypic differentiation in reproductive isolation, and we related the reflectance spectra of the feathers with the spectral sensitivities that had previously been reported for birds.
• how: The authors calculated the barbule reflectance spectra with a transfer matrix procedure as before in the study of the feathers . . .
