What is it about spring that makes birds become idiots. Every year we have at least one that falls in love with the reflection of itself in the window. This guy has spent the last few hours pecking at the window and trying to show off for its own reflection. If he is like birds from other years he will be here for days, trying to talk himself into mating.
Once in a while he lands for a few minutes, just to stare longingly into his own reflection. I have always heard that clean windows make it easier for them to see their own reflections....and I do my best to not get mine clean just for the birds....yeah that's it.
