GORHAM, N.H. (AP) — Early risers are celebrating International Migratory Bird Day with a guided walk in the White Mountain National Forest.

Forest biologist Lesley Rowse is leading a two-hour walk Saturday morning starting from Gorham. The program is meant to educate the public about the variety of birds, including warblers and thrush, that return each year to breed in the forest. Rowse says the location is an area that is usually bursting with the sounds of singing birds.
