This is the second time it's happened. I have an aspen tree next to the deck and in front of my living room window. I really don't see how the reflection of the sky or bird can be on the window because it is shady behind the tree, but I was in the other room and heard a BAM , something had hit the window. I thought maybe a kid had thrown a ball. I didn't see anything at first but looked around and this little guy was sitting on the deck. He was too stunned to move but just stared at me for long time. I just went away and thought he needed time to recover. He did and flew away. A few minutes later....BAM again. Was he trying to commit suicide? He finally did recover and flew off again. It happened last year too but with a large robin. This one was a baby. Maybe it's" like father, like son". Are they both just stupid? Or do I need to fear for my life because they are trying to attack me?
