The miners brought canaries down to tell when they'd hit a pocket of natural gas didn't they? I wouldn't say that because that was an indicator here it is absolutely an indicator here as well. Different gas means different results. It may be poisonus to the bird but harmless to a human.
Then again, it could be extremely toxic and you should GET OUT OF THE HOUSE RIGHT NOW
