Neornithes is the scientific term under which all the bird species are grouped, one of their main shared features is that their skin is covered with feathers, which subsequently form wings. Neornithes ventures into the realm of animal-sourced materials as it employs industrially dyed hen feathers presented in 13 different hues. De la Mora implements a distinctly rigorous methodology: he selects a reduced area of each feather, cuts it, and pastes it onto a paper which has been painted in either a matching color or contrasting one. As a result, the feather’s color interacts with its background as with the colors of the pattern devised by the artist. By proposing a new form of creating art with these organic elements, Gabriel de la Mora merges his interest in art history, in perceptual experimentation, and scientific research.
