fat robin in summer?
saw this very fluffed up robin the other day and was wondering why they're so round? I tried looking it up and kept finding things saying they'll puff up when it's cold to conserve their warmth, but it was pretty hot out that day. Does it work the same way to cool off? there were some other robins around in the yard (normal size and unpoofed) and this one took off not long after I took pictures, so I don't think it was injured. Just curious about it!!
