Lighting in Budgies

Light plays an important role in the health of all birds including budgies. The amount of light determines the natural clock of budgies and controls many aspects from alertness to reproductive behaviour.  Light also plays a direct role in the health of budgies.

When budgies are provided with light, their bodies produce vitamin D3.  Vitamin D3 helps the budgies absorb calcium from the food.  Hence, it is essential for budgies to have access to sunlight for 12 hours each day.

Natural lighting is ideal.  Leave a window open to allow in sunlight.  However, there are regions where the length of the day may vary with the seasons.  In these locations, it is better to have a lamp such as fluorescent lamp to provide light. 

Budgies are natives of Australia.  Hence, they are used to the tropical variations of night and day.  In tropical regions of the earth, the sunlight passes through the least atmosphere.  The light which reaches the native habitat of budgies undergoes very little filtering as it passes through the atmosphere.  Hence, any artificial light should be as close to sunlight as possible. 

This is determined by the Color rendering Index (CRI).  The colour rendering index indicates how closely an artificial light resembles natural sunlight.  Sunlight has a CRI of 100.  Hence, any artificial light should be as close to sunlight as possible.  A CRI of more than 90 would be ideal with a colour temperature close to the colour temperature of the sun which is 5500K.
