Abraham Lincoln's son, Robert Todd Lincoln, had the home built in 1908; at the time he was running the Pullman Railcar Company. The last of Abraham's daughters died here in 1978, and the estate was eventually taken over by the Friends of Hildene. In addition to the restored home and outbuildings, there is a fully restored Pullman luxury sleeper car under its own shelter, and a working goat farm on the property.
While this wasn't an ideal location for birding, there was a reasonable variety seen and heard on the property. There are several miles of trails to explore, but that will come another time.
Checklist for Hildene at Manchester:
The grounds and gardens (above) go right up to the cliff face (above, at right; at left), and provide spectacular views. there was always a refreshing breeze too.
