Feather morphological predictors of angle-dependent color changes in parrot plumage

Abstract: Among the most ornate animal traits in nature are the angle-dependent (e.g. iridescent) structural colors of many fishes, damselflies, birds, beetles, and butterflies. Though we now have a solid understanding of the mechanisms that create angle-dependent coloration in several groups, we know little about whether pigmentary colors reflect light in an angle-dependent fashion or if similar or different mechanisms govern angle-dependent reflectance from pigmentary versus structural colors. Here for the first time … Show more

“…5). However, variation in other hierarchical levels, such as feather microstructure, is increasingly being recognised as an important component of feather colour variation (Enbody, Lantz & Karubian, 2017; Eliason & Clarke, 2020; Iskandar et al ., 2016; McCoy et al ., 2018, 2021; Reed, Simpson & McGraw, 2020; Stavenga et al ., 2011, Urquia et al ., 2020). Microstructure is only beginning to be studied in a comparative context.…”

“…The (Stavenga et al 2011). Feather microstructure is responsible for variation in hue at different angles even in non-iridescent structural colors or primarily pigmentary colors (Reed et al 2020, Urquia et al 2020. In brown and black feathers, feather microstructure has been shown to explain more variation in coloration than melanin content alone (D'Alba et al 2014), highlighting the possible importance of microstructure in social signaling.…”
