After weeks of waiting for the right weather, my husband Bruce, always the designated driver, a new young birder in our area, Michael David, and I headed down to Sinking Valley to do our annual Winter Raptor Survey. It was a perfect day—fifteen degrees, still, and blue-skied.

We had a slow start, but finally Michael and I started seeing white spots sitting in trees. They all turned out to be red-tailed hawks. Sometimes we thought they might be something else and Bruce set up our scope. Nope! Only red-tails. This went on for most of the morning.

Since Michael was working on his county list, we noted other birds too. Robins eating staghorn sumac fruit. Twenty-six horned larks in the fields along Crawford Road so close we could almost touch them. A great blue heron sitting under a tree near the stream at the Arch Spring homestead. A pileated woodpecker clinging to a sapling near the road.

Ah! But I’ve saved the best for the last. After counting 26 red-tails and not even seeing a kestrel, we drove beneath what might be a kestrel. “Stop!” I yelled to Bruce and found I had made the same mistake as last year at the same place. A flock of mourning doves took off.

Then Michael started studying a flock of what he thought were starlings, but they turned out to be brown-headed cowbirds.

“I think I see a rusty,” he said and was out the car and down the road to study the flock more carefully. After all, my sons Steve and Mark had spotted a rusty blackbird in a flock of cowbirds during Christmas Bird Count, perhaps in this very same place.

I followed Michael at a slower pace and stood waiting for him to decide if he had found a rusty. Just as he had concluded that whatever he had seen had flown, I glanced idly across the barren, snow-covered field at a huge old tree standing by itself and saw two spots of white. I looked through my binoculars, expecting to see more red-tails and instead saw a pair of mature bald eagles, one sitting on the branch directly above the other.

Finally, raptors to get excited about! Michael wondered if they were a pair and perhaps nesting in the area. After all, this is the time of year when they begin building a nest. I certainly hope folks living in Sinking Valley keep an eye on this pair.

To cap the day, just after we saw the great blue heron, a golden eagle flew low over our car. Perhaps it was the same eagle Bruce and I had seen fly low over us while we walked on our Far Field Road several days ago.

Altogether, it was one of the more exciting Winter Raptor Surveys we have done over the years.
