WATERVILLE - Bald eagles have returned to Little Pine State Park and are exhibiting incubating behavior.
Park officials say they will not know how many eggs are laid until the chicks hatch and are large enough to life their heads above the rim of the nest.
Eagles have been nesting at the park since 2004, when they successfully raised one eaglet. Every year but one since then they successfully have raised two chicks.
Bald eagles return to the same nest each year, unless the nest tree is damaged or destroyed, or the adults are harassed.
The observation site for the nest is along the main road through the park, about 50 yards upstream from the entrance to the boat launch.
Visitors should park in the lot marked by the sign "Eagle Watch Area." Tables are provided for spotting scopes and a display provides information about eagles.
The nest is in a pine tree directly across the lake, at the shoreline when the lake is at normal level. The viewing distance is just more than 800 feet.
Observers are reminded it is illegal to disturb the nest site or to harass the adults.
An educational program about eagles will be held at 12:30 p.m. April 16 at the park's Eagle Watch Area.
Binoculars and spotting scopes will be available for use during the program.
