It was a bright, sunshine-filled Sunday afternoon when I pulled into the parking lot of Morton Wildlife Refuge in Noyac with my daughter, Angela, from San Francisco. The parking lot was jammed packed with vehicles. I found the only open spot — half in the woods, half out. With my camera and bag of black sunflower seeds at the ready, Angela and I proceeded into the reserve and followed the east trail, the one that takes you to the pond, the large tulip trees, and the state-endangered swamp cottonwoods.
