This is what I saw...
...a female cardinal batting her wings against the window.
We've had this stained glass picture hanging in the window for years, and although we have always had cardinals sitting in the tree peering in through the window, they have never done this before:
And she kept doing it, over and over again...
What magnificent wings and tail she has!
We assumed she was trying to attract the cardinals hanging in the window, so we took down the picture, and DOTH put up a plain sheet of paper. But still she kept flying into the window:
So we googled "cardinal flying repeatedly into window" and learned that the female cardinal is a fierce defender of her territory, especially if it is mating season and she is nesting nearby. So she was probably attracted both by the picture and the reflection of her own self -- and became her own worst enemy!
We also learned that while she is defending her territory (which went on all day yesterday and throughout today...and even as I type this), the male will come, from time to time, and feed her -- which is exactly what he did!
(we thought they were kissing at first!)
I don't want to tell you how long I stayed nearby, taking photos -- but I got a LOT of shots!
Still struggling with this new camera, though. I am sure my shots could have been much better.
