Turtles, frogs, and birds: Students from Ha:san Leadership Academy spent a cool May morning learning about all of the animals that call the Santa Cruz River in Tumacácori National Historical Park their home. Students learned from Michael Bogan about his research on the population of Sonoran mud turtles in the Santa Cruz. In addition to helping measure the turtles, students learned about other animals in the river, including bullfrogs, giant water bugs, and birds. Using Merlin, over 20 species of birds were recorded.
