tbh I think a lot of people don’t understand animal behaviour well in general, but they’re more likely to have come into contact/spent time with mammals like cats or dogs than birds, so it’s a whole new territory
i was surprised when i spent some time with captive birds though how often observers would see a bird on me (usually, frankly, making a menace of themselves while investigating) and seriously suggest i whack or shove it
another unfortunate one I’ve seen is people accidentally injuring/killing birds when trying to help them (injured wild birds, injured domestic birds, etc) because they grab them wrong or often, way too roughly
bird bones actually tend to be stronger than mammal bones due to density (also they have to support flight muscles), but on the flip side, mammal bones tend to break relatively cleanly, whereas birds have hollow/semi-hollow bones, which tend to shatter and splinter (leading to more complicated recoveries or in a lot of cases, unable to be fixed)
people also don’t realise that birds have air sacs in their body because they have air circulating (vs humans, where we have the good old in-and-out system), which again, is additional fine tissue to rupture if you’re handling them too roughly
