Spatially modulated structural colour in bird feathers by Andrew J. Parnell, Adam L. Washington, Oleksandr O. Mykhaylyk, Christopher J. Hill, Antonino Bianco, Stephanie L. Burg, Andrew J. C. Dennison, Mary Snape, Ashley J. Cadby, Andrew Smith, Sylvain Prevost, David M. Whittaker, Richard A. L. Jones, J. Patrick. A. Fairclough, Andrew R. Parker

“…Abstract Eurasian Jay (Garrulus glandarius) feathers display periodic variations in the reflected colour from white through light blue, dark blue and black. We find the structures responsible for the colour are continuous in their size and spatially controlled by the degree of spinodal phase separation in the corresponding region of the feather barb. …”
