Over and over she/he would fly directly from branch into window with a loud thud. You would think after the tenth or say eleventh time he might give up and realize that there was indeed an invisible barrier between him and our family room...but no. This continued throughout the day and quickly went from amusing to annoying. Repeated attempts to shoo and explain, 'hey bird, you're flying into a window...somebody is going to get hurt and i'm not driving to the emergency room (end statement used interchangeably between bird and kids) did not deter this spring robin's persistence.
Here's our little friend giving the window the evil eye as in the end the glass came out victorious. Hopefully today this silly birdie has gone on to do more mainstream bird things so I can get out there and Windex one bird smudged-up window.
