Let your birding begin at Book Family Farm for the early morning Bald Eagle fly-out from their foothill roosting site. The farms' fields attract Sandhill Cranes and a variety of resident and wintering birds. Our second stop will be at the Llano Seco Viewing Platform. This is an ideal spot for viewing a large number of geese and ducks in one location. Dress for potentially cold, wet weather and wear sturdy hiking footwear.
