178. Mercer Meadows, Lawrence Township, New Jersey

A 1,600-acre park north of Trenton where you can find raptors and owls in winter and songbirds and other migrants in spring and fall.

Hundreds of tall telephone poles once supported wire radio antennas on the 800 acres known as the Pole Farm. The facility was shuttered decades ago; now, after a grassroots campaign persuaded county government to stave off development, the farm and another 800-plus acres have been preserved.

The Pole Farm is the largest of five tracts composing Mercer Meadows, and it’s the best for birding.

I’ve been visiting for several years. I discovered the site by lucky accident while looking for raptors. A Northern Harrier skimming and hunting just a few feet above an open field prompted me to drive down a farm lane.

On subsequent visits, I was delighted to find that the park attracts not only harriers but also hawks, kestrels, Merlins, owls, and other raptors.

I’ve seen migrating warblers, Eastern Bluebirds, and other songbirds in the warmer months, but the deep-cold dead of winter is my favorite time. It’s when to see Short-eared Owls rising from treetops at sundown as they begin their twilight hunt for small mammals in the fields. In good years, I may spot several at once.
