Blue Heron Rookery on the Kentucky River

Juvenile great blue herons sat in their nest in a sycamore tree at a nesting site, also known as a rookery, along the Kentucky river palisades near Shaker Village at Pleasant Hill, Ky., on Friday, May 13, 2011. Shaker Village is offering two wildlife cruises to the blue heron rookery aboard their Dixie Belle paddleboat this spring.
