Autumn Avian Delights

Green Hills Preserve | Sat, October 14, 2017, 9:00am - 11:30am

Each autumn, hawks, sparrows, and songbirds flock across forests and fields, following age-old instincts to fly south for the winter. Join our morning bird walk to look for migratory and resident birds, including Field Sparrow, American Kestrel, Eastern Bluebird, and more. We’ll explore trails and enjoy the inspiring landscape of the 201-acre Green Hills preserve in Berks County.

Natural Lands partners with Baird Ornithological Club for this avian outing.

Green Hills Preserve is a bucolic mixture of gently rolling farm fields, woodlands, and wetlands. A tributary to Allegheny Creek, a state-designated “Cold Water Fishery” stream, bisects the preserve.

The Preserve is situated within the Schuylkill Highlands, a region at the nexus of two landscapes that have been prioritized for protection: the Highlands (as defined by the US Congress) and the Schuylkill River watershed. The area’s importance derives from the need to protect water quality, conserve habitat, and develop recreational opportunities in a region set for considerable growth over the next 20 years.

Located not far from an old stone springhouse—and fed by the cool, clear springs there—stands a towering red maple. This massive specimen has a trunk circumference of 188 inches (about five feet in diameter!) and is about 75 feet tall with a crown spread of 95 feet. In 2014, this giant was added to the official list of Pennsylvania Big Trees.

What to wear:
  • Dress for the season and wear sturdy, closed-toe shoes
  • Long pants and long-sleeved shirt, to protect you from poison ivy and brambles
  • Bug spray and hat are suggested
What to bring:
  • Refillable water bottle
  • Binoculars (and camera), if you have them
  • Please leave your four-legged friends at home.

Birders of all experience levels are welcome. Wear sturdy shoes and seasonal layers. Bring binoculars if you have them; a few will be available to borrow.

Meet Natural Lands staff member Debbie Beer in the parking lot at Green Hills. We’ll walk 1-2 miles at leisurely pace.
