Kirtland’s Warbler Tour

by Carl Strang

Last Thursday and Friday I drove into the northern part of Michigan’s Lower Peninsula. I had two goals, the first of which I’ll detail tomorrow. My secondary goal was to take the Kirtland’s warbler tour. This is a seasonal education opportunity offered by the U.S. Fish & Wildlife Service and Michigan Audubon (nearly done for this year). The tours begin with a video introduction at the Ramada in Grayling, and then the guide leads participants in a car caravan to the tour site. We drove to an area where the current crop of jack pines was mainly 3-5 feet tall.

The pines are on a harvest rotation, with large areas clear-cut and replanted, so that there always are large areas covered with the small pines the warblers favor.

Kirtland’s warbler is a federally endangered species, but the population trend is upward and the range is expanding thanks to the intense management efforts. Now some are breeding in Wisconsin and Ontario as well as both peninsulas of Michigan. The rarity of the species draws birders to the area, and about 15 of us were on the Friday morning tour.

Allison, our guide, was knowledgeable, and there were plenty of competent birders in the group to assist with the spotting.

The area appears to be structurally and botanically fairly simple. The pines were dominant in the area, with scattered oaks and cherries the other large woody plants.

Jack pine has short needles and small, curved cones.

Between the pines were a few shrubs, mainly huckleberries or blueberries, as well as sweetfern, one of my favorites.

The wonderful odor of sweetfern leaves I associate with wild places. Sadly it does not occur in DuPage County, as it is a sandy soil species.

Among the herbaceous plants were scattered hairy puccoons.

This is another sandy soil plant.

The puccoons frequently threw off some of the more anxious birders whose search image was tuned to the color yellow. Kirtland’s warbler males were singing loudly at all times, but for a while they stayed out of sight. In the meantime we enjoyed a surprising diversity of birds for such a simple ecosystem: four sparrows (field, vesper, clay-colored, Lincoln’s), 3 warblers (Kirtland’s, Nashville, palm), nighthawk, upland sandpiper, brown thrasher, towhee, Brewer’s blackbird, and rose-breasted grosbeak were notable ones. Eventually a male Kirtland’s warbler perched and sang on an exposed branch.

This is an expanded view of the dot on my photo that represented the warbler. We had good spotting scope views.

The tour was highly satisfying. However, it did not allow me to further my primary goal, which was to find Roesel’s katydids in the Lower Peninsula. More on that tomorrow.

    Good luck with the katydids. If I let it, I think sweetfern would takeover all the unwooded areas on my property. It’s nice to have lots of it.
