The Parrot Pro Lamp With Stand to assist your Pet Birds and Parrots Health and Well-being through providing essential Vitamin D3. ntroducing the Parrot PRO-LAMP with Stand. If your home does not generate enough sunlight then this will be a great help for your Pet Bird/s. A lack of Vitamin D3 and calcium can cause feather plucking, bad behaviour in birds and reptiles. Vitamin D3 is the only vitamin that normally requires a specific type of light (ultraviolet light, which comes from the sun) to convert it into its active form. When birds in the wild ingest Vitamin D in their food, the sun’s ultraviolet fraction converts it into a fundamental component of good health. Without this exposure to sunlight Vitamin D deficiency problems can develop in birds.
