Plain-English summary
Three canaries were found to have severe feather loss on their legs, back, neck, and head, along with thickened skin on their feet. Unfortunately, due to their poor health, they were euthanized for further examination. Tests revealed a fungal infection caused by Mucor ramosissimus, which was damaging their feathers and skin. This case is significant as it is the first known instance of this fungus causing skin problems and feather loss in canaries or any birds.

Abstract
Three canaries showing feather loss on legs, dorsum, neck, and head, and hyperkeratosis on the feet were sacrificed because of their poor corporal condition and submitted to the Unit of Histology and Anatomic Pathology at the Veterinary School of Las Palmas de Gran Canaria. Histologically, skin revealed pronounced epidermal and follicular infundibular hyperplasia associated with orthokeratotic hyperkeratosis. Numerous fungal spores were observed on the stratum corneum of the epidermis and within feather follicles, associated with destruction of the feathers. This fungus was identified as Mucor ramosissimus. To the best of authors' knowledge, this is the first report of dermatitis and feather loss associated with Mucor ramosissimus, not only in canaries but also in birds.
