Texas state ornithologist Cliff Shackelford answers all your bird questions on his "Bird Calls" radio show. One of Rick Torres' passions is leading families on night hikes at Ray Roberts Lake State Park. Exploring the depths of Texas' artificial reefs, documenting species of fish and coral, and monitoring the health of our reefs are all in a day's work for members of the TPWD Artificial Reef Program.
