Parrot suitable light source,
The first requirement is illuminance, the second is the spectrum, one is indispensable,
Lack of either, if there is less interaction between bird companions or owners, may lead to behaviors that we do not like to see such as self-harm, screaming or aggression.
Why?
Because there are three kinds of photoreceptor cells in birds, more sensory cells than humans that perceive ultraviolet rays, so birds have fully applied ultraviolet rays in evolution and developed some specific functions
Confidence: Bird feathers can reflect a more brilliant metallic color under ultraviolet rays,
Foraging: For example, birds of prey can see ultraviolet reflections from rodent urine excretion
Pairing, courtship and reproduction: For example, when a tiger parrot is in heat, the color spots on the cheeks of the two cheeks show a brilliant color that can only be reflected by ultraviolet rays
So light is definitely a necessary factor for the psychological construction and physiological needs of birds, most wild birds receive full-day sunlight for at least three hours in the native area, while water birds, shore birds or birds of prey are more than five hours, so in addition to the full spectrum should be added moderate ultraviolet UVA and UVB, UVB irradiation of the skin will convert vitamin D2 into vitamin D3 that allows the body to absorb calcium, and UVA is the key to real feathers and colorful birds to have self-confidence, and then pair courtship and reproduction
If the increase of UVB indoors is to allow the skin to absorb vitamin D, it is not necessary, one of which is that vital D is not lacking in a rich variety of foods, and may be excessive for parrots (because most parrots hide in leafy forests)
The second UVB in the country is difficult to find a suitable light source for birds, reptile lights are too high UVB index, some jungle birds are not suitable for but vision, skin, etc. may be damaged, in foreign countries have long had this case of excessive use of UVB, such as the Amazon
Third UVB overdose is dangerous,
If you really want to set up a daylight light source indoors, you can use UVA, UVA so that birds can have a rich color environment, not only in food, but also in the feathers there are physical colors that humans can not see in the UVA light source to show color, birds in this environment not only have a greater interest in natural vegetables and fruits, but also the environment, companions of the exploration and curiosity, but also show their natural nature (such as feathers instead of tails), and will not bite hair or self-harm
So I use it indoors
Philips TLD 36w/08 UVA BLB Black Tube*1+
2.LED 6000k 2300 lm *4 (illuminance 10000 lux or more) as a virtual light source for daylight, and they like to stand on the perch in front of the light to groom each other, bathe and eat
And to match people's schedules
In the early morning, only LED*1 (illuminance 2300 lumens) 1.5 hours,
LED *3 (6900 lumens) + UVA (36w) 3.0 hours (full daylight time is recommended not to exceed 3 hours),
After the afternoon, the indoor light source is extinguished and the natural light is maintained obliquely
Until the evening, the dim indoor light with a color temperature of 3000 is used to facilitate the rest of the family and the bird treasure
Let's look at the IRR range and UV effect presented by the UVA BLB black lamp alone (night test)
The irradiation range covers the entire aviary
