FRANKFORT — To see migrating raptors this fall, check out the Hawk-Watch on Cadillac Mountain in Acadia National Park. To watch vultures (a.k.a. “buzzards” or “turkey hawks”) demonstrate their dramatic flying techniques, hike Mount Waldo by late September.

Tucked behind Route 1A-abutting Mosquito Mountain, Waldo rises 1,064 feet from the surrounding blue-berry barrens and forests. Except for its accident-prone quarry, the mountain receives little publicity, yet no better combined views of coastal and interior Waldo County exist anywhere else.

From mid-spring to late September, vultures patrol the Mount Waldo skies while seeking carrion. On a warm, sunny day — and especially as young vultures fledge — several vultures may fly in loose formation.

They ride the updrafts caused where the sun heats Waldo’s granite ledges and the spotty open terrain beneath the mountain’s slopes. The vultures soar, dip, wheel, and seemingly float above the beautiful landscape stretching from Prospect west to Swan Lake and the Dixmont Hills.

Often a vulture appears as a distant black speck against the September sky. Minutes later that speck becomes a wing-spread vulture sailing with the wind high overhead, occasionally circling to re-examine a possible food source before slipping away to con-tinue the hunt.

Although not always present when hikers ascend Mount Waldo, vultures can stage quite a show when they’re there. Vultures apparently pay close attention to the mountaintop and hunt among the towers, their guy wires, and the scraggly trees.

I have witnessed vultures, their attention transfixed on what might be dead and rotting beneath them, perform violent, last-second acrobatic maneuvers to avoid wing-severing guy wires. This 90-degree “up” and 90-degree “over” wing flip (vultures never really seem to “flap” their wings) leaves me awe-struck at how well these big birds maneuver.

Sometimes a vulture descends lower over Waldo’s open ledges and presents a striking photographic op-portunity by framing itself against a clear or cloudy sky. When a vulture does this, and especially if the bird hovers above a watching hiker, does this suggest that the vulture knows something the human does not?

When Victor or Vicky Vulture circles tightly over my balding head and gives me the twice-over, I certainly hope I’m not next on the buzzard menu.

As the adjacent forests transition from green to variegated in late September, Mount Waldo sees other vultures flitting through its skies during the fall migration. Hawks also pass over Waldo while working south along the coast. I watched one small hawk plummet over Waldo’s southwestern ledges to attack a circling vulture; neither bird paused to explain that avian dispute, which ended with the vulture wheeling away toward Searsport.

The Waldo County foliage peaks by Columbus Day weekend, and Mount Waldo’s unofficial Vulture Watch winds down about that time, too. Between now and then, pack binocu-lars, snacks, and some drinks and hike Mount Waldo on a sunny day.

Enjoy the birds and the foliage.
