Some birds also get confused by glass, although they do seem better able to consider an alternative (e.g. an open door) when one presents itself. My dataset is the small number that sometimes get into my shed when the door is open.
Tangential glass/bird related story time. I occasionally see small birds pecking at their reflection in glass. I once saw a Long-Tailed Tit pecking at my shed window and watched it for a few seconds. And then it went one way, and the reflection went the other! That's when I realised that there was a bird on the inside as well. Cue rescue mission (opening the shed door).
