Today a group of us had a guided tour of Crex Meadows near Grantsburg, Wisconsin.  We saw many birds but the trumpeter swans are the easiest for me to photograph.  We also saw song sparrow, chipping sparrow, field sparrow, kestrel, robins, morning doves, mallards, buffleheads, coots, Northern shovelers, blue winged teal, Northern harrier, a rough legged hawk doing acrobatics in the sky, sandhill cranes, Canadian geese, yellow rumped warblers, bald eagles, and blue birds.  It was a great day to stand outside and look for birds!  The same rug company that used the cord grass to make rugs out at Carlos Avery Wildlife Management Area also owned the property that is now Crex Meadows.  We don't use cord grass for our rugs anymore.  Now we use petroleum products to make our rugs. I guess a few are made out of wool but I wish we used more sustainable materials for our rugs instead of petroleum products.
