EDIT: Ive removed some of this post as some statements were inaccurate.
If I told my aunt about candles being dangerous she would laugh in my face and call me stupid, she's had a cockatiel for 16 years and she doesnt know much about birds at all. She cares for it, loves it, plays with it and it has massive amounts of out of cage time, all day in fact, but she got it so long ago that people werent educated in how to care for birds.
She is absolutely oblivious to such things as candles, teflon-cookware etc, wood types, plants etc, and the bird is fine. I am not by any means saying that this is a good a approach, I actually believe the contrary, that you should always educate yourself, and do the best you can to eliminate dangers BUT, this discussion got me thinking a little bit; maybe we're overdoing it sometimes?
(And I know that some of you will say that its better to be on the safe side, and I do agree with you

).
Ive NEVER heard of any other pet owners being so paranoid as we as bird people are, be it dog, cat, rodents or whatever. Do we really need to be so overly protective?
(I am still going to, but lets think about it shall we?)
I believe that you should educate yourself, learn the dangers and avoid them, but unless there is nothing that suggest there is a danger, should we really refrain from our ordinary habits?
I am on rambling here...but my main point isnt that you should light candles, I hope you all got that, but rather that we should try and evaluate if our behaviour as bird people is justified, do we really have to worry as much as we do? I strongly believe in educating ourselvs though!
And on the candle note, EDIT: they are dangerous to birds!
