I don’t know how it started – I heard it, but didn’t see it.
There was a harsh thud against the window. If you are used to it (I have heard it enough) you know that a bird has struck the glass. Generally hard enough to stun or kill. Break their necks. When he was a child, my father saw a bird hit a window so hard that it smashed the glass and ended inside the room. It was dead.
So I got out of my chair and pulled the blinds open and took a look. By the sidewalk was a blackbird, dead enough looking for me to assume it was dead. As it proved to be. But, also on the scene were five or six blackbirds, calling and fluttering and diving and raising right hell .I thought it an unusual commotion even for the death of one of their own,
And then I looked up into the fir tree on the corner of the property. A third of the way from the ground was a crow. A very cautious crow. A crow twisting its head every which way it could.
Now, I did not see what made the blackbird crash into the window. It is reasonable to assume the crow was somehow the cause. Blackbirds chase crows, and dive bomb them, and worry them, and harry them, and do so with the help of other blackbirds. Crows like to raid their nests and eat their eggs or their young. A crow is a big bird compared to a blackbird. Strength in numbers.
So, I suspect the dead blackbird made an in flight miscalculation while chasing the crow. It got too close. Then, as it tried to get out of range, it crashed into the window. I was quick to look out the window, and the crow was already in the tree. It may have lunged at the blackbird, or spread its wings. or aimed its beak. The blackbird moved too quickly in its attempt to get out of the way.
But the crow was not out of the woods yet. It wasn’t going to take to the sky and attempt an escape. A half dozen blackbirds could inflict injury on the crow. It was going to stay put.
I had the unusual experience of being nearly level with the crow. I watched it. I watched its head. I watched its eyes. Birds have active, cautious, suspicious eyes. Their eyes are large in relation to their heads. Their eyes are jammed into their eye sockets, so they are generally unmovable. Consequently, when they want to move their eyes, they have to move their head.
So, this crow was moving its head a lot.
Five or six blackbirds kept hovering and diving. Even two blue jays joined in the ruckus, screeching in the background at all the commotion.
This went on about five minutes, then the other birds departed. A couple of minutes later, the crow lifted from the branch. It had murder in its eyes.
