I was going through my drafts and I found this post from early July and thought some might still enjoy it.
This summer we had an unusual visitor to our kitchen window, a yellow finch (identified by our nephew who knows a lot about birds or at least a lot more than I do). The interesting thing is this bird kept coming back for about 2 weeks.
The reason he kept coming back is (at least we think) he was looking for his buddy's.
Who had some designs beyond playing.
My wife and I joked that we think he recognized the screen and window offered him protection. He would usually not fly onto the window sill unless the cats were present. He almost seemed to taunt them, we can definitely confirm that he did cause some frustration.
We hope he comes back next summer (and our cats hope we open a window, so he can come in and play :-).
