Xi'an's Og

A moderately interesting article in the NYT on why birds crash into (my) windows and the limited efficiency of bird stickers, esp. those glued from the inside. Just like insects, who have difficulties understanding the concept of glass (!), birds fly into glass windows because they do not realise they are there. What I find surprising in the case of my own house is that they (fairly rarely) crash into windows of rooms with no perspective, i.e. with a wall behind the window. Birds never enter when these windows are open, for instance. One possible explanation is that under some lighting the window is reflecting the outside for the flying bird rather than the inside of the house. Supporting this explanation is the observation that the crashes I noticed occur around the same time in late Fall, when sun is quite low. (And no connection other than coincidence with yesterday’s post on Thunderbird!)
