Back again this year

All last summer and into the fall there was a little yellow finch that tried over and over to get through my glass windows from outside. It was uncanny. It would peck on my window panes, fluttering its wings, for minutes at a time before flying away and returning again soon. The fact that I was sitting here at my computer not much more than two feet away from it didn't seem to deter its mission. Now I see it is back again. Could it be the same one or is this a trait of yellow finches?
