Bird Feather Science

Autor: Author, Karanjekar, Rucha S & Pravin N Charde

'The basic structure of feather is described in this book. And a new logic of feather science is applied to study the feathers. This book reveals the application of a new and innovative concept called ptilochronology to study the sexual behavior of b

A longitudinal analysis of the growth rate and mass of tail feathers in a great tit population: ontogeny, genetic effects and relationship between both traits

Autor: Iván de la Hera, Michael S. Reichert, Gabrielle L. Davidson, John L. Quinn

Publikováno v: Journal of Avian Biology, Vol 2022, Iss 5, Pp n/a-n/a (2022)

Feathers have a diversity of functions in birds and are costly to produce, so their growth rate and mass can be reliable indicators of nutritional condition at the time of production. Despite the potential for feather metrics to advance our understan

Feather steroid hormone concentrations in relation to age, sex, and molting time in a long‐distance migratory passerine

Autor: Marie Adámková, Zuzana Bílková, Oldřich Tomášek, Zdeněk Šimek, Tomáš Albrecht

Publikováno v: Ecology and Evolution, Vol 9, Iss 16, Pp 9018-9026 (2019)

Abstract In birds, concentrations of testosterone (T) and corticosterone (Cort) are closely connected with many morphological, behavioral, and other physiological traits, including reproduction, metabolism, immunity, and fitness. The direction of the
