Right I had a light in the office room which was shaped like a bowl on a tall stick - there was the light element in the center of the bowl. It gave great light but I always worried about a bird accidentially landing on or in the bowl and getting burnt, so I changed it out for a much safer light.
As much as we might think "oh the keet will never land there", there is always the chance that the keet will get scared by something and flop in a direction by accident, so it's best just not to have dangerous things around
Yup candles can be VERY dangerous because a keet is in essence a ball of feathers. Just one tiny touch of flame would cause their entire body to go up in flames, that would be bad.
