I took Rosie out into the backyard with her Harness to get some sun and take some photo’s :) Sun is great for birds feathers and health.
I found a great website with information on why Parrots should be out in the sun at least a little bit every week.
"There really is no adequate replacement for natural sunlight, but if this is not possible, you should provide your bird with a good-quality artificial light bulb that emits the ultraviolet portion of the spectrum."
"Now, think about our pet birds. Most pet birds spend all of their lives indoors, except for the occasional trip in a plexiglas carrier or covered travel cage to the vet or groomer. You might think that your pet bird receives adequate light exposure because it sits by a window and you often see it enjoying the warmth of the sun. However glass, plastic and even fine-mesh screening filters out most of the beneficial UVB rays of the sun."
Can birds get sunburned? Yes! Over-exposure to direct sunlight (the ultraviolet portions of the spectrum: UVA and UVB) can cause sunburn on the unfeathered facial skin. Feather-plucked birds can also get sunburned skin on the areas with no feather covering, although I have not seen this occurring as frequently as sunburn of the face. The feet, covered with scales, are protected from most of the effects of sunburn. Mutations that cause a bird to be of a color palette that is not the natural “wild-type” color are more susceptible to the effects of the sun’s burning rays.”
