Andrew Johnson never expected to be president, but just six weeks after becoming Abraham Lincoln's vice president, he was thrust into the nation's highest office. Johnson faced a nearly impossible task — to succeed America's greatest chief executive and to bind the nation's wounds after the Civil War. Annette Gordon-Reed shows how ill-suited Johnson was for this daunting task. His vision of reconciliation abandoned the millions of former slaves and antagonized congressional leaders, who tried to limit his powers and eventually impeached him.

Annette Gordon-Reed is the Pulitzer Prize-winning author of Thomas Jefferson and Sally Hemings: An American Controversy and The Hemingses of Monticello: An American Family. She is Professor of Law at Harvard Law School, Professor of History in the Faculty of Arts and Sciences at Harvard University, and the Carol K. Pforzheimer Professor at the Radcliffe Institute at Harvard University. Her latest book is Andrew Johnson, in the American Presidents Series.

In the heart of New York City's bustling metropolis, Central Park's 36-acre Ramble is a bird watcher's paradise, where more than 270 species have been spotted in a single year. With New York being located along one of North America's busiest migratory routes, the spring months are an ideal time to spot the city's avian visitors on their trip north.

Journey with wildlife artist and illustrator Alan Messer to some of the most magical places in Central Park's wooded Ramble, discovering along the way both resident and migrating birds. Walks are limited to 35 guests per tour.

During the April walks through Central Park's Ramble, we will search for resident, late winter, and early migrants, including common birds at feeders. Chickadees, nuthatches, woodpeckers, finches, and sparrows may be seen at this time.

Alan Messer is a wildlife artist and illustrator of books, field guides, and periodicals. He is a former president of the Linnaean Society of New York. Mr. Messer's illustrations are included in the exhibition, Focus on Nature XI, on view at The New York Museum, Albany, New York from April 12 through October 31, 2010.
