Tuesday, March 12, 2012 SW of Trenton, Gibson Co. I had my first Barn Swallow of the season just down the road from my house on Tuesday afternoon. This is my first Barn Swallow of the season. I now have 4 male Purple Martins at the nesting colony in my yard. Chipping Sparrrows have also returned to the yard after a 3 month absence and have started gathering nesting materials. Good birding, Mark Greene Trenton, TN Gibson County
