Genetic and Molecular Basis of Feather Diversity in Birds ...

Feather Diversity among Breeds of Domesticated Birds A large repertoire of mutant phenotypes of domesticated birds has been accumulated in the past hundreds of years. In particular, chickens and pigeons display a great degree of variation in feather color, distribution and texture, body shape and size, leg length and width, and a host of other traits ( Bartels 2003 ; Chen et al. 2015 ; Domyan and Shapiro 2016 ).

Birds of a Feather: Capturing Avian Shape Models from Images ...

Animals are diverse in shape, but building a deformable shape model for a new species is not always possible due to the lack of 3D data. We present a method to capture new species using an articulated template and images of that species. In this work, we focus mainly on birds. Although birds represent almost twice the number of species as mammals, no accurate shape model is available. To ...

Feather diversification allows different species of birds to be widely distributed on earth and adapt to various ecological niches in water, land, and air (Chatterjee 2015). A great diversity of feather can also be observed within a bird species, especially in domesticated birds ( Bartels 2003 ; Chen et al. 2015 ; Boer et al. 2017 ; Domyan and ...
