Lehigh Valley bird sightings for September 29

Bake Oven Knob in Lehigh County is the place to be at this time of year. Thousands of raptors have begun their annual migration south, and they use the ridge of the Blue Mountain as their guide. The topography of the ridge makes it easy to see the birds as they soar close to the mountain.
