Research day 3: The week of Wood Thrush in a nutshell

For Friday mornings I took the truck out and headed north along the Susquehanna to the more picturesque town of Harding along 92. I stopped when I could where there was forest and did playback for Wood Thrush. I did this for two hours and that totals about 10 hours of Wood Thrush searching for the week. I totally struck out yesterday. Stopped to pee (as I do more often then days) and found the graffiti below. It says "BIROS SUCK" and I read it as "BIRDS SUCK".
