Birds like reptiles use sunlight in every aspect of their day to day life in the wild. They use the wavelengths of light that we call UVA to view the world in a spectacular way. This helps them with mate selection and for finding food and is now thought to help with migration. This is called Tetrachromacy.
Birds also use the wavelengths of light that we call UVB to start a chemical change in the blood that enables them to produce their own Vitamin D3 “the sunshine vitamin” this then allows the absorption, storage and use of Calcium.
Hummingbirds originate from an area that has a very high UV index. They use this powerful sunlight to thrive in the wild. Their iridescent plumage is readily used in active communication and mate section. As such it is vital that the average wild index of the species is re-created in captivity. This will then allow the hen to choose the cock as she would in the wild and to go onto copulate and produce young. This upper index can now be safely re-created with Arcadia High output T5 UVB systems.
For the biggest flights the Arcadia SuperZooT5 is the number one choice of the professionals.
