That's a clickbait title, the article implies that a lot of kitchen fumes are toxic to birds and that can include fumes released when a skillet is left on the stove with nothing in it. It could me that teflon is worse than everything else, but there is not enough information to reach this conclusion. Would a plastic handle melting and burning on the stove be better? Chili fumes of strengths that make humans cough and eyes water? I don't yet see evidence that if one gets rid of teflon, it's Ok to cook around birds without same precautions.
