With the sun fully out and the temperature a cool 51 degrees, I headed to the Mercer Meadows Pole Farm this morning for my first home outing since returning from Maine.

I had checked Birdcast to find that warblers are returning to Mercer County on their fall migration, and I hoped I’d chance upon a few. I stretched my neck muscles, anticipating some upward glances with my binoculars and, if lucky, my camera.
Walking the central path, I spotted a bobolink framed by grasses and heard one more farther up. Reaching the woods, I was ready for warblers.
As I turned toward the AT&T Building One site, I noticed several birders training their binoculars into the trees to the left, an area I call the “warbler wall.” Most springs and falls, that stretch of trees has been a magnet for northbound and southbound travelers.

One of the birders had spotted a Canada warbler, and with a laser pointer she circled the leaves where she believed it was visiting. Some minutes later, she announced it was at the bottom of that tree, and I was able to watch the bird fly off.
We spent about 20 minutes watching the activity in the trees, and there was plenty. At least one black-throated green warbler was zipping about, as were blue-gray gnatcatchers, Eastern pewees, a ruby-throated hummingbird and an American redstart. A Carolina chickadee came by, and a Northern flicker and hairy and downy woodpeckers put in appearances.
I didn’t realize one of the birds I shot was the redstart, a female as I would learn at home when looking at my photos.

While most of the birders moved on, I hung back with one of them and another walked in to join us. We had a nice chat about birding hotspots in New Jersey and Delaware. Suddenly, one of them spotted a red bird on a tree branch. His first thought was Northern cardinal but then blurted out, “scarlet tanager!”
Highlighted by the sun, the bird was a male with dark black wings and scarlet body. But there was a patch of yellow on its flank, signaling the change to winter plumage had begun.
It’s good to be home, and I hope all the southbound travelers make it home, too. 🦅
