As usual Andrew beat me too it! I would add one point LEDs are increasingly 
used in bird husbandry and a small byproduct is that there limited heat 
output may be just sufficient to maintain an ambient >30 degrees when 
confined to the nacelle. This is why Mynas commonly use the heat exchanger 
of air-con units. It allows the adults additional foraging time. Ciao
