Knemidocoptes sp. These mites burrow in the epidermis of the legs on birds, causing scales to lift and become loosened and the legs to become thickened and deformed. K. pilae is the species that commonly infest parakeets while K. mutans and K. jamaiciensis infest gallinaceous birds and canaries respectively. This case was resolved after oral administration of Ivermectin in drinking water.
