Behavior/Health Concerns:  Although the Rock pebbler is not prone to illness or disease, they can get intestinal worms or fungal infections if they are not kept inside or in an outdoor aviary with a clean, cement floor free of dirt due to their natural instincts to eat on the ground. A variety of fresh fruits and vegetables will please these pet birds. Male rock pebblers have a mostly yellow body with olive plumage around the crown and neck. The male bird’s wings are also mostly yellow. A broad red band is located on the inner wing converts of males and the band is bluish-black on the outer wing coverts. Female rock pebbles are a more olive color and their red bands are duller. Female rock pebblers have a blue-green tail with pink tip on the underside. While the male and female rock Pebblers have color distinctions, western-born males are a duller yellow color, making it more difficult to decipher between the sexes.
